The process of disorderly deleveraging which had started in 2007 intensified from end-February, with asset markets becoming increasingly illiquid and valuations plunging to levels implying severe stress. However, markets subsequently rebounded in the wake of repeated central bank action and the Federal Reserve-facilitated takeover of a large US investment bank. In sharp contrast to these favourable developments, interbank money markets failed to recover, as liquidity demand remained elevated.Mid-March was a turning point for many asset classes. Amid signs of short covering, credit spreads rallied back to their mid-January values before fluctuating around these levels throughout May. Market liquidity improved, allowing for better price differentiation across instruments. The stabilisation of financial markets and the emergence of a somewhat less pessimistic economic outlook also contributed to a turnaround in equity markets. In this environment, government bond yields bottomed out and subsequently rose considerably. A reduction in the demand for safe government securities contributed to this, as did growing perceptions among investors that the impact from the financial turmoil on real economic activity might turn out to be less severe than had been anticipated. Emerging market assets, in turn, performed broadly in line with assets in the industrialised economies, as the balance of risk shifted from concerns about economic growth to those about inflation.Credit market turmoil gives way to fragile recoveryFollowing two weeks of increasingly unstable conditions in early March, credit markets were buoyed by a cautious return of risk tolerance, with spreads recovering from the very wide levels reached during the first quarter of 2008. Sentiment turned in mid-March, following repeated interventions by the Federal Reserve to improve market functioning and to help avert the collapse of a major US investment bank. As these actions alleviated earlier concerns about risks to the financial system, previously dysfunctional markets resumed trading and prices rallied across a variety of risky assets.2BIS Quarterly Review, June 2008Between end-February and end-May, the US five-year CDX high-yield index spread tightened by about 144 basis points to 573, while corresponding investment grade spreads fell by 63 basis points to 102. European and Japanese spreads broadly mirrored the performance of the major US indices, declining by between 25 and 153 basis points overall. Between 10 and 17 March, all five major indices had been pushed out to or near the widest levels seen since their inception. They then rallied back and seemed to stabilise around their mid-January values, remaining significantly above the levels prevailing before the start of the market turmoil in mid-2007 (Graph 1).business lines, tightening repo haircuts caused a number of hedge funds and other leveraged investors to unwind existing positions. As a result, concerns underlying exposures are almost entirely protected by federal guarantees, as summer of 2007 (Graph 3, right-hand panel).BIS Quarterly Review, June 20083Fears about collapsing financial markets reached a peak in the week March, triggering repeated policy actions by the US authorities. investment grade credit default swap (CDS) indices underperforming lower-quality benchmarks (Graph 4, left-hand and centre panels). Spreads were temporarily arrested when, on 11 March, the Federal Reserve announced an expansion of its securities lending activities targeting the large US dealer banks (see section on money markets and Table 1 below). European CDS indices tightened by more than 10 basis points on the news, while the two key basis points down, respectively (Graph 1). allowing it to make secured advance payments to the troubled investment These developments appeared to herald a turning point in the market, funds target down to 2.25%. Earnings announcements by major investment banks on 18 and 19 March that were better than anticipated provided further support, with investors increasingly adopting the view that various central bank initiatives aimed at reliquifying previously dysfunctional markets were gradually gaining traction. Consistent with perceptions of a considerable reduction in systemic risk, spreads, and particularly those for financial sector and other investment grade firms, tightened from the peaks reached in early March(Graph 4). Movements were partially driven by the unwinding of speculative short positions, as suggested by changes in pricing differentials across products with similar exposures, according to the ease with which such positions can be opened or closed. For example, spreads on CDS contracts referencing the major credit indices moved more strongly than those on the same indices’ constituent names (Graph 1, centre and right-hand panels). Similarly, CDS markets outperformed those for comparable cash bonds, as market participants adjusted their synthetic trades.risks (Graph 1, centre and right-hand panels). Similarly, implied volatilities from CDS index options eased into the second quarter, indicating a somewhat reduced uncertainty about shorter-run credit spread movements (Graph 3, centre and right-hand panels).losses based on ABX prices (see box). This was despite the lack of a recovery for the index series with lower original ratings, whose prices continued to4 BIS Quarterly Review, June 2008BIS Quarterly Review, June 20085suggest expectations of complete writedowns of all underlying bonds by mid-2009 (Graph 2, centre panel). At these low levels, and with none of the ABX indices having experienced any principal writedowns so far, investors appeared to be pricing in the possibility of legislation writing down mortgage principal. Against this background, issuance of private-label mortgage-backed securities remained depressed, with volume growth coming mainly from US agency-Supported by optimism about banks’ recapitalisation efforts, spreads pace of capital replenishment. Following news of a rights issue on 31 March, CDS spreads referencing debt issued by Lehman Brothers tightened. UBS announced large first quarter losses and a fully underwritten capital increase on 1 April, and other institutions followed over the rest of the month. Globally, banks managed to raise more than $100 billion of new capital in April alone, stemming the deterioration in capital ratios. Financial CDS spreads, the monoline segment excluded, outperformed corresponding equity prices in the process (Graph 4, right-hand panel), reflecting diminishing concerns about imminent financial sector risk as well as the dilutory effects of equity financing. Markets retraced some of these gains in early May, partially driven by strong supply flows from corporate issuers that included, at $9 billion, the largest US dollar deal by a non-US borrower in seven years. Volumes were dominated by6 BIS Quarterly Review, June 2008Pitfalls in using the ABX. Estimated mark to market losses and actual writedowns made by banks and other investors can differ for a variety of reasons. Analysts, depending on their objective, thus have to be mindful of potential sources of bias. At least three such sources can be identified, of which two are specific to the ABX index:•Accounting treatment. Subprime MBS are held by a variety of investors and for different purposes. While large amounts of outstanding subprime MBS are known to reside inbanks’ trading books, banks and other investors may also hold these securities tomaturity. This can result in different accounting treatments, which would tend to deflateactual writedowns and impairment charges relative to estimates of mark to market losseson the basis of market indices, such as the ABX. The size of this effect, however, isdifficult to determine. Further complexities are added once securities cease to be tradedin active markets, implying the use of valuation techniques, which may differ acrossinvestors, in establishing fair value.5•Market coverage. ABX prices may not be representative of the total subprime universe, due to limited index coverage of the overall market. Original balance across all four serieshas averaged about $31 billion. This compares to average monthly MBS issuance ofsome $36 billion over the 10 quarters up to mid-2007, ie almost a month’s worth ofsubprime MBS supply per index series. Similarly, with 2004–07 vintage subprime MBSvolumes estimated at around $600 billion in outstanding amounts, each series representssome 5% of the overall universe on average. At the same time, ABX deal composition isknown to be quite similar in terms of collateral attributes (such as FICO scores and loan-to-value ratios) to the overall market (by vintage).6 Therefore, despite somewhat limitedcoverage, this particular source of bias may not be large.•Deal-level coverage. Similarly, ABX prices may not be representative because each index series covers only part of the capital structure of the 20 deals included in the index(see Graph A, right-hand panel, for an illustration).7 In particular, tranches referenced bythe AAA indices are not the most senior pieces in the capital structure, but those with thelongest duration (expected average life) – the so-called “last cash flow bonds”. Theseclaims will receive any cash flow allocations sequentially after all other AAA trancheshave been paid; and tend to switch to pro rata pay only when the highest mezzaninebond has been written down. It follows that AAA ABX index prices are going to reflectdurations that are longer, and effective subordinations that are lower, than those of theremaining AAA subprime MBS universe. As a result, using newly available data for MBStranches with shorter durations, the $119 billion of losses implied by the ABX AAA indicesas of end-May would be some 62% larger than those implied under more realisticassumptions.8_________________________________1 See, for example, International Monetary Fund, Global Financial Stability Report, April 2008, pp 46–52, and Box 1 in Bank of England, Financial Stability Report, April 2008.2 Supplementary indices, called ABX HE PENAAA, were introduced in May 2008 to provide additional pricing information for all four existing vintages.3 An alternative approach, likely to lead to very different results, would estimate future default-related cash flow shortfalls on the basis of deal-level or aggregate data for subprime securities. To obtain these estimates, such methodologies rely on information about collateral performance and require the analyst to make assumptions about structural relationships and model parameters. Typical subprime loss projections, for example, use delinquency data and assumptions about factors such as delinquency-to-default transitions, default timing, and losses-given-default. See Box 1 in the Overview section of the December 2007 BIS Quarterly Review for an example on the basis of an approach devised by UBS. 4Mark to market losses (relative to par) are calculated assuming that unrated tranches are written down completely; ABX prices for the BBB– indices are used to mark BB collateral; rated tranches from the 2004 vintage are assumed unimpaired; outstanding amounts remain static.5 For details, see Global Public Policy Committee, Determining fair value of financial instruments under IFRS in current market conditions, December 2007.6 See, for example, UBS, Mortgage Strategist, 17 October 2006. 7 Incomplete coverage at the deal level further reduces effective market coverage: typical subprime MBS structures have some 15 tranches per deal, of which only five were originally included in the ABX indices. As a result, each series references less than 15% of the underlying deal volume at issuance.8 Duration effects at the AAA level are bound to be significant for overall loss estimates as the AAA classes account for the lion’s share of MBS capital structures. Using prices for the newly instituted PENAAA indices, which reference “second to last” AAA bonds, to calculate AAA mark to market losses generates an estimate of $73 billion. This, in turn, translates into an overall valuation loss of $205 billion (ie some 18% below the unadjusted estimate of $250 billion).capitalisation had recovered, while remaining weaker than before the crisis. At the same time, still-elevated implied volatilities suggested ongoing investor uncertainty over the future trajectory of credit markets. With the credit cycle continuing to deteriorate and related losses on exposures outside the residential mortgage sector looming, it was thus unclear whether liquidity supply and risk tolerance had recovered to an extent that would help maintain this improved environment on a sustained basis.Bond yields recover as markets stabiliseFrom its low point on 17 March, the 10-year US Treasury bond yield rose by 75 basis points to reach 4.05% at the end of May. During this period, 10-year yields in the euro area and Japan climbed by around 70 and 50 basis points, respectively, to 4.40% and 1.75% (Graph 5, left-hand panel). In US and euro area bond markets, the increase in yields was particularly pronounced for short maturities, with two-year yields rising by 130 basis points in the United States and by almost 120 basis points in the euro area (Graph 5, centre panel). Two-year yields went up in Japan too, but by a more modest 35 basis points. In addition to reduced safe haven demand for government securities, the rise in short-term yields reflected a reassessment among investors of the need for monetary easing, following the stabilisation of financial markets.In the first two weeks of March, as the financial turmoil deepened and forward rates dropping (Graph 6, right-hand panel). While flight to safety and other effects relating to the volatility in financial markets may have influenced consistent with the observed fall at the short end of the forward break-evencurve. At the same time, these same concerns led investors to increasinglyexpect the Federal Reserve to maintain a more accommodative policy stancethan normal in an effort to contain the fallout on economic growth. Insofar asthis was seen as likely to lead to higher prices down the road, it could explainthe rise in distant forward break-even rates at the time.As the situation in financial markets stabilised after the rescue of BearStearns in mid-March, and perceptions of the economic outlook improvedsomewhat, the US forward break-even curve shifted in the opposite directionand flattened considerably. To a large extent, this shift in the forward curve islikely to have reflected a reversal of the same influences that had been at playin the first two weeks of March: the dampening effect on prices coming from theturmoil was perceived to be weaker after mid-March, while the Federal Reservewas seen to be less likely to deliver further sharp rate cuts. Moreover, upwardprice pressures appeared to intensify in the short to medium term, with foodprices rising continuously and oil prices reaching new all-time highs during thisperiod (Graph 5, right-hand panel), pushing near-term forward break-evenrates further upwards.real yields reflected a combination of expectations of higher average realinterest rates in coming years and a reversal of flight to safety pressures. Theformer component, in turn, was due to perceptions among investors that thereal economic fallout from the financial turmoil was likely to be less severe thanhad previously been anticipated. This was despite indications of deterioratingconsumer confidence amid tighter bank lending standards and continuedweakness in US housing markets. The revival in investor confidence seemedinstead to follow from the stabilisation in markets and from a number ofrelatively upbeat macroeconomic announcements. These included better thangovernment securities.In line with perceptions that the stabilisation of markets had reduced therisks to economic growth somewhat, prices of short-term interest rateindicating expectations of a period of stable rates, followed by rising rates inthe first half of 2009 (Graph 7, left-hand panel). In the euro area, EONIA swapprices at the beginning of March had signalled expectations of sizeable ECBrate cuts, but by end-May prices had shifted to reflect expectations of graduallyincreasing policy rates (Graph 7, centre panel). Meanwhile in Japan,expectations of mildly falling policy rates in March had by May been revised toindicate rising rates (Graph 7, right-hand panel).A turning point for equity prices?to end-2007 levels, gained almost 10% between 17 March and end-May. Equity markets in Europe and Japan, which had seen losses in excess of 20% between the turn of the year and 17 March, subsequently also displayed a strong recovery, with the EURO STOXX gaining 11% and the Nikkei 225 rising Reflecting the improved situation in financial markets during this period, by almost 20% and 34%, respectively. These gains occurred despiteannouncements by several banks of record losses during the first quarter amidcontinued credit-related write-offs. Investors obviously took solace from the factthat losses – although big – were no worse than expected, and that a numberof banks had been successful in their recapitalisation efforts (see credit marketsection above).surprises remained well above that of negative surprises, provided somesupport for equity prices. In addition, as fears failed to materialise that economic growth might slow dramatically in the first few months of the year,investors increasingly began to see equity valuations as attractive following thesharp price declines in late 2007 and early 2008. markets recovered after a sharp dip in March (Graph 8, right-hand panel).Emerging market investors discount growth risksequities fell up to mid-March, before rebounding in the wake of the change inmarket sentiment following the Bear Stearns rescue in the United States.Between end-February and end-May, the MSCI emerging market indexgained about 4% in local currency terms, and was up more than 14% from thelows established in mid-March. Latin American markets, which had seen ahigh trading volumes in commodity derivatives (see the Highlights section inthis issue) and speculative demand as a source of part of that strength, otherspointed to low supply elasticities and expectations of sustained rates ofindustrialisation throughout the emerging markets. With the region being amajor net commodities importer and natural disaster contributing to weakerequity prices in China, Asian markets were broadly flat over the period.Emerging Europe, in turn, remained exposed to the risk of a reversal in privatecapital flows, owing to large current account deficits and associated financingneeds in a number of countries. Nevertheless, strong gains in Russia and thebetter than expected growth performance of major European economies in thefirst quarter seemed to aid equity markets in May.Emerging market credit spreads, as measured by the EMBIG index,accounting for most of the spread tightening, the EMBIG remained almost flatin return terms, gaining about 1.1% between end-February and end-May(Graph 9, left-hand panel). Large stocks of foreign reserves and favourablemacroeconomic performance in key emerging market economies continued toprovide support, aiding the market recovery. Spread dispersion remained high,pointing to ongoing price differentiation according to credit quality (Graph 10,centre panel). At the same time, with inflation running well above target in anumber of major emerging market economies, policy credibility appeared tobecome more of a concern, putting pressure on local bond markets. Risinginflation expectations, combined with increasing US Treasury yields andrelatively resilient markets during the earlier stages of the recent marketturmoil, may thus have contributed to a somewhat more muted performancefrom emerging market bonds relative to other asset markets over the periodsince mid-March.Tensions in interbank markets remain highas high at the end of May as three months earlier, across most horizons and inall three major markets (Graph 10). This appeared to imply expectations thatinterbank strains were likely to remain severe well into the future.After a relatively smooth turn of the year, interbank market tensions hadappeared to ease somewhat until early March 2008, and Libor-OIS spreadshad shown some signs of stabilising. However, as the financial turmoilsuddenly deepened in the second week of March, following an acceleration inmargin calls and rapid unwinding of trades (see the credit section above),interbank market pressures quickly increased. With market rumoursproliferating about imminent liquidity problems in one or more large investmentbanks, banks became increasingly wary of lending to others. At the same time,their own demand for funds jumped as they sought to avoid being perceived ashaving a shortage of liquidity.Selected central bank liquidity measures during the period under review7 March The Federal Reserve increases the size of its Term Auction Facility (TAF) to $100 billion andextends the maturity of its repos to up to one month.11 March The Federal Reserve introduces the Term Securities Lending Facility (TSLF), which allowsprimary dealers to borrow up to $200 billion of Treasury securities against collateral. Theexisting dollar swap arrangements between the Federal Reserve and the ECB and the SNB areincreased from a total of $24 billion to $36 billion.16 March The Federal Reserve introduces the Primary Dealer Credit Facility (PDCF), which providesovernight funding for primary dealers in exchange for collateral. The Federal Reserve alsolowers the spread between the discount rate and the federal funds rate from 50 to 25 basispoints, and lengthens the maximum maturity from 30 to 90 days.28 March The ECB announces that the maturity of its longer-term refinancing operations (LTROs) wouldbe extended from up to three months to a maximum of six months.21 April The Bank of England introduces the Special Liquidity Scheme, under which banks can swapilliquid assets for Treasury bills.2 May The Federal Reserve boosts the size of its TAF programme to $150 billion, and announces abroadening of the collateral eligible for the TSLF auctions. The dollar swap arrangements withthe ECB and the SNB are increased further, from $36 billion to $62 billion.Source: Central bank press releases. Table 1The near collapse and subsequent takeover of Bear Stearns onMarch highlighted the risks that banks face in such situations. On the would not be allowed to fail, and this helped restore order in other markets. On the other hand, the speed with which Bear Stearns’ access to market liquidity had collapsed underscored the vulnerability of other banks in this regard, which kept Libor-OIS spreads high even as CDS spreads on banks and brokerages Throughout the period, central banks maintained and even stepped up activity from central banks seemed to have limited immediate impact oninterbank rates. To some extent, this may have reflected the fact that while thesums involved in central bank liquidity schemes were large in absolute terms,they were still rather limited compared to banks’ assessment of their overallliquidity needs against the background of a sharp decline in traditional sourcesof funding. One significant source of short-term funding for banks in the pasthas been money market mutual funds. Such funds have seen substantialinflows since the outbreak of the financial turmoil (Graph 11, left-hand panel),reflecting a noticeable reduction in investors’ appetite for risk. However, thisloss of risk appetite also resulted in money market funds shifting theirinvestments increasingly into treasury bills and other safe short-term securities,hence depriving banks of a key funding source (Graph 11, centre panel). Thissuggests that determining how persistent the interbank tensions will be maydepend significantly, among other things, on how long the risk appetite ofmoney market fund managers, and investors more broadly, will continue to bedepressed.。

Evidence of the voice-related cortical potential:An electroencephalographic studyJessica Galgano and Karen Froud ⁎Department of Biobehavioral Sciences,Teachers College,Columbia University,USA Received 1October 2007;revised 4March 2008;accepted 12March 2008Available online 21March 2008The Bereitschaftspotential (BP)is a slow negative-going cortical potential associated with preparation for volitional movement.Studies since the 1960s have provided evidence for a BP preceding speech-related volitional motor acts.However,the BP associated specifically with voice initiation (i.e.a volitional motor act involving bilateral true vocal fold adduction)has not to date been systematically investigated.The current investigation utilizes a novel experimental design to address methodological confounds typically found in studies of movement-related cortical potentials,to demonstrate the existence and localization of generators for the voice-related cortical potential (VRCP).Using high-density EEG,we recorded scalp potentials in preparation for voice onset and for exhalation in a stimulus-induced voluntary movement task.Results showed a slow,increasingly negative cortical potential in the time window of up to 2500ms prior to the mean onset of phonation.This VRCP peaked at a greater amplitude and shorter latency than the BP associated with exhalation alone.VRCP sources were localized to the anterior rostral regions of the medial frontal gyrus (Supplementary Motor Area (SMA))and in bilateral laryngeal motor areas before and immediately following the mean initiation of phonation.Additional sources were localized to the bilateral cerebellum and occipital lobe in the time window following the mean onset of phonation.We speculate that these results provide additional support for fine somatotopic organization of the SMA.Further examination of the spatiotemporal change of the VRCP yielded source models which indicated involvement of the laryngeal motor cortices and cerebellum,likely responsible for the initiation and continuation of phonation.©2008Elsevier Inc.All rights reserved.IntroductionThe event-preceding brain component associated with prepara-tion for volitional movement,referred to as the Bereitschaftspo-tential (BP),has been described in detail over many years of research (Kornhuber and Deecke,1965;Deecke et al.,1969,1976).Several studies have attempted to identify and isolate the BP related specifically to preparation for speech.For example,Brooker and Donald (1980)put a significant amount of consideration into matching the time constants of instrumentation,and included EMG recordings of several muscles that are active during speech.Wohlert (1993)and Wohlert and Larson (1991)investigated the BP preceding speech and nonspeech movements of various levels of complexity.Both experiments controlled for respiratory artifact by having subjects hold their breath prior to task initiation.In addition,electro-ocular and EMG activity were monitored,and (in the 1993study)a pneumatic respiration transducer was utilized to monitor breathing patterns.Additionally,EMG activity from the orbicularis oris muscle was used to trigger and average segments.More recent advances in electroencephalo-graphic and electromyographic techniques have made it possible for examinations of this nature to more accurately identify BPs associated with vocalization and oral movements.These advances have also permitted investigations aiming to specify the cortical and subcortical pathways involved in volitional control of exhalation,which is required for voice production.Kuna et al.(1988)found thyroarytenoid muscle activity during exhalation,suggesting that cortical control of volitional respiration may be related,in part,to the requirement for precise management of vocal fold position during respiration.Although a significant amount is understood about the BP,it has been difficult to extract these components from EEG recordings,since the BP is typically a slow change in amplitude with a wide bilateral distribution (Brooker and Donald,1980;Deecke et al.,1986;Ertl and Schafer,1967;Grabow and Elliott,1974;McAdam and Whitaker,1971;Morrell and Huntington,1971;Schafer,1967),representing shifts of only a few microvolts.Thus,accurate triggering by the exact onset of movement is extremely important.Studies attempting to identify the BP associated with the volitional motor act of laryngeal or vocal fold movement (which we will refer to as the V oice-Related Cortical Potential,or VRCP)have encountered other obstacles too:in particular,difficulties withco-/locate/ynimg NeuroImage 41(2008)1313–1323Corresponding author.Department of Biobehavioral

fold movement onset,and methodological confounds between voice, speech and language(Brooker and Donald,1980;Deecke et al., 1986;Ertl and Schafer,1967;Grabow and Elliott,1974;McAdam and Whitaker,1971;Morrell and Huntington,1971;Schafer,1967). In addition,respiratory artifact or R-wave contamination of the BP preceding speech has proven a major difficulty,particularly in early studies(Deecke et al.,1986).Larger-amplitude artifacts due to head-,eye-,lip-,mouth movements and respiration must also be eliminated before signal averaging(Grözinger et al.,1980).Earlier studies investigating voice-related brain activations typically confounded the distinctions between voice,speech and language.Voice refers to the sound produced by action of the vocal organs,in particular the larynx and its associated musculature. Speech is concerned with articulation,and the movement of organs responsible for the production of the sounds of language—in particular,those of the oral tract,including the lips,tongue and nguage refers to the complex set of cognitive operations involved in producing and understanding the systematic processes which underpin communication.Therefore,studies which have at-tempted to isolate voice or speech-related activity by the use of word production instead have described activation relating to a combina-tion of these cognitive and motor operations(for example,Grözinger et al.(1975)used word utterances amongst their tasks designed to elicit speech-related activations;Ikeda and Shibasaki(1995)used single words as well as nonspeech-related movements like lingual protrusion;McAdam and Whitaker(1971)used unspecified three-syllable words to elicit ostensibly speech-related activity).Con-versely,in a magnetoencephalography(MEG)study,Gunji et al. (2000)examined the vocalization-related cortical fields(VRCF) associated with repeated production of the vowel[u].Microphones placed close to the mouth were used to capture the sound waveform from the vocalization;the onset of the waveform provided the trigger for segmenting and averaging epochs.This design carefully attempts to identify vocalization-related fields;however,operationalizing a procedure which is able to most closely capture the onset of voicing is particularly difficult.Difficulty stems,in part,from the limited number of compatible neuroimaging techniques and instruments able to capture these phenomena.The present study contributes to understanding of the timing and distribution of the VRCP by addressing two major sources of methodological confound:the blurring of distinctions between voice, speech and language;and the accurate identification of movement onset for triggering and epoch segmentation.Furthermore,we use high-density EEG recordings,providing an increased level of detail in terms of the scalp topography,and additionally enabling the application of source modeling techniques to ensure accurate identification of the VRCP.Our results provide novel insight into voice generation by addressing the following research question: Can the true VRCP,associated only with laryngeal activity,be isolated from related movement potentials,by utilizing the right combination of control and experimental tasks?We predicted that a stimulus-induced voluntary movement paradigm would yield significant differences in the characteristics of the Readiness Potentials associated with(a)initiation of phonation and(b)respiration.To be specific,we predicted the existence of an isolable voice-related cortical potential associated only with prepara-tion for initiation of phonation and greater amplitude of the VRCP vs. the respiration-related cortical potential.We also predicted that VRCP sources would be localized to the Supplementary Motor Area, primary motor cortices,and sensori-motor regions.Elucidation of the neural mechanisms of normal voice is a crucial step towards understanding the role of functional reorganization in cortical and subcortical networks associated with voice production, both for changes in the normal aging voice,and in pathological populations.This approach to determining the neural correlates of voice initiation could provide a foundation for creating neurophy-siologic models of normal and disordered voice,ultimately informing our understanding of the effects of surgical,medicinal and/or behavioral interventions in voice-disordered populations. The findings could ultimately provide us with new basic science information regarding the relative benefit of different treatment approaches in the clinical management of neurogenic voice disorders.In addition,the larger significance of this work is related to the fact that voice disorders are currently recognized as the most common cause of communication difficulty across the lifespan,with a lifetime prevalence of almost30%(Roy et al.,2005). Materials and methodsA stimulus-induced voluntary movement paradigm in which trials of different types were presented in subject-specific rando-mized orders was utilized.This method addressed the documented problem of the classic BP paradigm which involves self-paced movements separated by short breaks:the person is already conscious of and preparing for a particular movement and there is a known repetition rate of the movements(Libet et al.,1982,1983). This can lead to automatic movements,which change the presentation of the VRCP.In our procedure,it is not possible for the participant to predict ahead of time which task they have to perform,which allows for a spontaneous movement.The movements were chosen to avoid another methodological confound,between voice,speech and language tasks.Requiring subjects to produce linguistically complex units,such as sounds or words(e.g.Ikeda and Shibasaki,1995;Wohlert and Larson,1991; Wohlert,1993)led to some debate concerning whether BPs for speech might be lateralized to the dominant hemisphere for language.This problem is avoided in the current study,and the problem of movement artifacts involved in speech and speech-like movements such as lip-pursing or vowel-production(Gunji et al., 2000;Wohlert and Larson,1991;Wohlert,1993),in particular of back,tense,rounded vowels(such as the[u]used in Gunji et al's experiments),by utilizing a task which involves voicing only,and has no related speech or language overlay.The actions of breathing out through the nose,and gentle-onset humming of the bilabial nasal [m]without labial pressing,are equivalent actions in terms of involvement of the articulatory tract,the only difference being the initiation of vocal fold movement in the humming condition.By having participants breathe or hum following a period of breath-holding,the possibility of R-wave contamination is also reduced (Deecke et al.,1986).Onset of phonation is established by mea-suring vocal fold closure using electroglottography(EGG),and a telethermometer attached to a trans-nasal temperature probe was used for the earliest possible identification of exhalation onset. Subjects24healthy subjects(21females and3males)with an age range of21–35years of age(mean age=26years)participated in the study.All subjects were informed of the purpose of the study and1314J.Galgano,K.Froud/NeuroImage41(2008)1313–1323gave informed consent to participate,following procedures ap-proved by the local Institutional Review Board.All participants took part in a training phase,which was identical to the experi-mental procedure and served to train participants on the expected response to each screen.Each step of the procedure was discussed and explained as it was occurring,and there was ample opportunity for feedback to be provided to ensure accurate task performance.EEG/ERP experimental set-up and proceduresEEG data acquisitionScalp voltages were collected with a 128channel Geodesic Sensor Net (Tucker,1993)connected to a high-input impedance amplifier (Net Amps200,Electrical Geodesics Inc.,Eugene,OR).Amplified analog voltages (.1–100Hz bandpass)were digitized at 250Hz.Individual sensors were adjusted until impedances were less than 30–50k Ω,and all electrodes were referenced to the vertex (Cz)during recording.The net included channels above and below the eyes,and at the outer canthi,for identification of EOG.The EEG,EOG,stimulus triggered responses,EGG and telethermometer data were acquired simultaneously and later processed offline.Recording of respirationA nasal telethermometer (YSI Model 43single-channel)with a small sensor (YSI Precision 4400Series probe,style 4491A)was placed 2–4cm inside one nostril transnasally and used to measure the temperature of inhaled and exhaled air.Readings from the telethermometer were digitally recorded by interfacing the teletherm-ometer with one outrider channel input to the EEG net amplifier connection,for co-registration of the time course of respiration with the continuous EEG.Recording of voice onsetA Kay Telemetric Computerized Speech Lab,Model 4500(housing a Computerized Speech Lab Main Program Model 6103Electroglottography)with 2electrodes placed bilaterally on the thyroid cartilage,adjacent to the thyroid notch,was used to measurevocal fold closure and opening.The EGG trace was acquired in the Computerized Speech Lab (CSL)proprietary software and co registered offline with EEG and telethermometer recordings,in order to determine error trial locations and confirm onset of vocal fold adduction and controlled exhalation.V oice sounds were also recorded by microphone on a sound track acquired on the CSL computer,sampling at 44.1kHz.A response button box permitted participant regulation of the start of each trial.At each button press,an audible “beep ”was generated by the system which provided an additional point of co-registration between the EGG system and the time of trial onset.In addition,pressing the button permitted the subject to move to the next trial set from a screen that allowed physical adjustment into a more comfortable position if needed in between tasks (to reduce movement artifact).Instructions and experimental taskThe experimental task required subjects to hold their breath for 4s,followed by breathing out or humming through the nose.The action carried out was determined by presentation of a “Go ”screen after the breath-holding interval;the “Go ”screen randomly presented either a “Breathe ”or “Hum ”instruction.To avoid using language-based stimuli in this experiment,the instructions to breath or hum were represented instead by letter symbols:a large 0for breathing,and a large M for humming.There were eighty trials altogether (forty voice and forty breathe).Experimental stimuli were presented using Eprime stimulus presentation software (Psychology Software Tools,Pittsburgh,PA).Subjects were visually monitored via a closed circuit visual surveillance system,to ensure compliance with experimental conditions.Each trial (breathe or hum)was followed by a black screen,which indicated to participants that they could take a break before the next trial,swallow,blink and make themselves comfortable (this was intended to reduce movement artifacts during trials).Participants used button presses to indicate when they were ready to continue on to the next trial (Fig.1).Data analysisRecorded EEG was digitally low-pass filtered at 30Hz.Trials were discarded from analyses if they contained incorrectresponses,Fig.1.The following experimental control module display shows the timeline of stimulus presentation during the experiment.Initially,a red screen instructed the subject to hold their breath with a closed mouth (4s).This was followed by a green screen which displayed either an “M ”or “0”,prompting the subject to hum or breathe out,respectively.Following each trial,a black screen instructed the subjects to make themselves comfortable to minimize movement artifact before moving onto the next trial.When subjects were ready,a button press triggered an audio beep which allowed for co-registration of instrumentation being utilized.1315J.Galgano,K.Froud /NeuroImage 41(2008)1313–1323eye movements (EOG over 70µV),or more than 20%of the channels were bad (average amplitude over 100µV).This resulted in rejection of less than 5%of trials for any individual.EEG was rereferenced offline to the average potential over the scalp (Picton et al.,2000).EEG epochs were segmented from −3000to +500ms from onset of voicing or exhalation,and averaged within subjects.Data were baseline-corrected to a 100ms period from the start of the segment,to provide additional control for drift or other low amplitude artifact.For identification of ERPs and for further statistical analyses,two regions of interest (ROIs)were selected:the Supplementary Motor Area (SMA)ROI,and the Primary Motor Region (M1)ROI.The 7SMA sensors were centered around FCz,where SMA activations have previously been reported (e.g.Deecke et al.,1986).The M1ROI consisted of 25sensors,centered anterior to the central sulcus and located around the 10–20system electrodes F7,F3,Fz,F4,F8,A1,T3,C3,Cz,C4,T4,A2(listed left-to-right,anterior-to-posterior),where Motor-Related Potentials have been previously identified (Jahanshahi et al.,1995).See Fig.2.Statistical analysesData from averaged segments were exported to standard statistical software packages (Microsoft Excel and SPSS),permit-ting further analysis of the ERP data.Repeated measures Analysis of Variance (ANOV A)was used to evaluate interactions and main effects in a 2(Condition:voicing vs.breathing)×2(region:SMA vs.M1)×3(time window:pre-stimulus,stimulus to voice onset,and post-voice onset)comparison.The dependent variable was grand-averaged voltages across relevant sensor arrays,determined following data preprocessing.The ANOV A was followed by planned comparisons,and all statistical analyses employed the Greenhouse –Geisser epsilon as needed to deal with violations of assumptions of sphericity.Point-to-point differences in mean amplitude between the 2conditions (humming vs.breathing)were evaluated for statistical significance,using separate repeated measures t -tests performed on mean amplitude measures within a 4ms sliding analysis window.Bonferroni corrections were employed to control for type 1error arising from multiplecomparisons.Fig.2.This sensor layout displays the 128-channel Geodesic Sensor Net utilized in the current experiment.Legend:Black=SMA montage;Grey=M1montage;Black+Grey=Channels entered into Grand Average.1316J.Galgano,K.Froud /NeuroImage 41(2008)1313–1323VRCP.Time-locking of the segmented EEG to the onset of true vocal fold adduction as recorded from the electroglottograph enabled identification of the standard BP topography,with a peak at the time of the movement onset,followed by a positive reafferent potential.The topography of the VRCP was examined using true vocal fold (TVF)adduction onset obtained from the EGG recording,and is subject-specific.Individual averaged files were placed into group grand-averages.The VRCP was identified in individual averaged data and in group grand-averages,based on the distribution and latency of ponent duration and mean amplitude for each subject(and for grand-averaged data)in each experimental condition were calculated.Three pre-movement components of the VRCP were measured, i.e.early(−1500to−1000ms prior to movement onset),late(about −500ms prior to movement onset),and peak VRCP(coincides with or occurs approximately50ms prior to movement onset)(Deecke et al.,1969,1976,1984;Barret et al.,1986).To determine the onset of each VRCP component,mean amplitude traces from individual and grand-averaged voice trials were examined independently by scientists with BP experience(Jahanshahi et al.,1995;Fuller et al., 1999).The mean latency of the early VRCP(rise of the slope from the baseline),the late VRCP(point of change in slope),and the peak VRCP(most negative point at or prior to vocal fold closure)were measured.The slope of the early VRCP was calculated(in microvolts per second)between the point of onset of the early VRCP and the onset of the late VRCP.The slope of the late component was calculated from the point of onset of the late VRCP to the onset of the peak VRCP.A2(region:SMA vs.M1)×2(time window:early VRCP te VRCP/late VRCP vs.peak VRCP)repeated measures ANOV A,followed up with planned comparisons,was used to examine interactions and main effects.BESA.In order to model the spatiotemporal properties of the VRCP sources,we used Brain Electrical Source Analysis(BESA: Scherg and Berg,1991).Source modeling procedures were applied to the voice produc-tion condition only(not to the exhalation condition).This is because a telethermometer was used to record changes in temperature associated with inhalation and exhalation;however,these associated changes do not reliably correlate with the true onset of exhalation or thyroarytenoid muscle activity associated with exhalation,as evidenced by the wide variety of measures reported in the literature for determination of respiration onset(e.g.Macefield and Gandevia (1991)used EMG measured over scalene and lateral abdominal muscles;Pause et al.(1999)used a thermistor placed at the nostril to determine onset of respiration based on changes to air temperature; Gross et al.(2003)determined onset of respiration to be associated with highest cyclic subglottal pressure;and other methods have also been reported).Source localization approaches are therefore not appropriate for the exhalation condition;consequently,we con-ducted comparisons between potentials associated with exhalation and voice using statistical analyses of differences in amplitude only. Source localization procedures were conducted on the voice pro-duction condition,because in that condition we were able to identify the initiation of voicing,using electroglottography.BESA attempts to separate and image the principal components of the recorded waveform as well as localizing multiple equivalent current dipoles(ECDs).Any equivalent current dipole was fit to the data over a specified time window,and the goodness of fit was expressed as a percentage of the variance.Our procedure for developing the ECD model was closely based on procedures detailed in Gunji et al.(2000),as follows.First,we selected an interval for analyzing the data in terms of a spatiotemporal dipole model.Following Gunji et al.,we selected the interval of−150ms to+100ms,because this interval covered the approximate period from the onset of the instruction screen to preparation to move the vocal folds,through to onset of phonation and the start of auditory feedback.Gunji et al.further recommend a dipole modeling approach limited to this time interval in order to focus on brain activations just before and after vocalization,rather than attempting to model the complex and persistent sources associated with Readiness Potentials.We therefore seeded sources and fit them for orientation and location in the time window from −150ms to0ms(the averaged time of the start of phonation).The time window from0to+100ms was examined separately.Sources seeded in both time windows are described below.ResultsIndividual data were grand-averaged and component identifica-tion was based on distribution,topography,and latency of activations (individual subjects and grand-averaged data).AVRCP was identified in all subjects,maximized over fronto-central electrodes(overlying the SMA).For grand-averaged data,all electrodes overlying the SMA showed a large VRCP in the specified time window(see Fig.3). Voicing vs.Controlled Exhalation ConditionsThe ANOV A revealed that the triple Condition×Region×Time interaction was significant(F(1,124)=2488.463,p b.0001),as were both two-way interactions(Condition×Region,F(1,124)=68.428, p b.0001;Condition×Time,F(1,124)=1808.242,p b.0001; Region×Time,F(1,124)=6651.504,p b.0001).Planned compar-isons revealed that the mean amplitudes of the VRCP were significantly more negative than the BP associated with the controlled exhalation condition,and SMA amplitudes were significantly more negative than M1.The significant interaction between Condition and Region for all subjects was found to be due to the fact that,although SMA sensors were always significantly more negative than M1 sensors(t(1939.233)=26.272,p b.0001),there was a greater difference in the measured negativities in V oice trials compared to Breathe trials(see Fig.4).Further examination of the main effect of Time revealed that,as time progressed,mean amplitudes became significantly more negative(i.e.VRCPs became significantly more negative from the pre-stimulus time window to the time of voice onset and beyond). Investigations of the Condition by Time interaction revealed sig-nificant progressive increases in the measured negativities from early to late time windows for the V oice condition.However, subjects showed a greater degree of negativity in the pre-and post-screen time windows for the breathe condition only(see Fig.5).For the Controlled Exhalation/Breathing Condition,the SMA BPs from stimulus to exhalation were significantly more negative than in the pre-stimulus interval.The M1region,however,showed no significant increase in negativity until the later time windows.In other words,over the SMA sensors the movement-related negativity increased in the period leading to exhalation,as well as later;over the M1sensors,however,readings did not become significantly more negative until after movement.Investigations of the Region×Time interaction for the voicing trials showed a significant increase in the negativity over both the SMA and M11317J.Galgano,K.Froud/NeuroImage41(2008)1313–1323regions between the pre-stimulus interval and the time to voice onset.Mean amplitudes continued to become significantly more negative across time intervals post-voice onset for both regions.This is summarized in Table 1and shown in Fig.5below.To summarize,several significant findings were revealed.The voicing condition was significantly more negative than the exhalation condition,activation over SMA sensors was significantly more negative than over M1sensors,and negativities significantly increased over the three time windows for the voice condition only.VRCP slope changesThe 2×3repeated measures ANOV A examining changes in the VRCP slope (microvolts per second)revealed a significant main effect of time,with the earlier time window being associated with ashallower slope than the later time window in both Regions.No other main effects or interactions were significant.Source localization using BESAUsing BESA,we fit dipoles to the grand-averaged data from 23subjects'responses to the V oice condition.We accepted an ECD model as a good fit when the residual variance dropped to 25%or below (standard for fitting to data from individuals is 10%RV).We began by seeding pairs of dipole sources to the left and right laryngeal motor areas,and in the middle frontal gyri,known to be associated with oro-facial movement planning in humans (Chainay et al.,2004)and the origination of human motor readiness potentials (Pedersen et al.,1998),respectively.A final pair of dipoleswasFig.3.The above waveform demonstrates grand-averages of 24subjects.In the voice condition,a peak negativity of the VRCP (SMA:−10.0086,V;M1:−5.2983,V)was found at bilateral TVF adduction,evidenced by onset movement shown in the Lx (EGG)waveform.A standard BP topography in M1is revealed.The late VRCP in M1shows a steeper slope,positive deflection preceding movement onset,and longer latency when compared to SMA.In the breathe condition,peaks showed longer latencies over both M1and SMA sensors,and reduced amplitude over SMA.Steps in the stimulus presentation/analysis procedure are superimposed:the breath-holding screen starts at −4000ms,and the “Go ”screen (instruction to hum through the nose)appears after 4s of breath-holding and is shown for a further 4s period.Initiation of phonation (recorded by EGG)was established for each individual trial within each subject.The interval between the onset of the “Go ”screen and phonation is where the specific VRCP could be identified.1318J.Galgano,K.Froud /NeuroImage 41(2008)1313–1323。

Leaning against the wind ow, Harry coul d see Hogwarts coming nearer, its many lighted wind ows blurred and shimmering behind the thick curtain of rain. Lightning flashed across the sky as their carriage came to a halt before the great oak front doors, which stood at the top of a flight of stone steps. Peopl e who had occupied the carriages in front were already hurrying up the stone steps into the castle; Harry, Ron, Hermione and Nevill e jumped d own from their carriage and dashed up the steps too, l ooking up only when they were safely insid e the cavernous, torch-lit Entrance Hall, with its magnificent marbl e staircase.马车穿过两边带翅膀野猪雕塑的大门，顺着宽敞的车道行驶，由于狂风大作，马车剧烈地摇晃着。
