• The precentral gyrus (+anterior portion of paracentral lobule) is somatomotor area, which control contralateral movements
• The postcentral gyrus (+posterior portion of paracentral lobule) is somatosensory area, which receives impulses from contralateral somatic sensory organs.
Connections of the striatum
Major interconnections of the basal ganglia
Functions of Basal Nuclei
• Influence muscular activity
– Subconscious control of skeletal muscle tone and coordinates learned movement patterns
