WebOne of the brain areas most involved in controlling these voluntary movements is the motor cortex. The motor cortex is located in the rear portion of the frontal lobe, just before the central sulcus (furrow) that separates the frontal lobe from the parietal lobe. The motor cortex is divided into two main areas, Area 4 and Area 6. WebBoth receive basal ganglia output but differ in primary projection patterns. Pf sends large excitatory projections directly to the striatum (the main input area of the basal ganglia), while VAL projects back to the cortex. Despite their critical place in the movement system, little is known about their changing roles in motor learning.
