of oculomotor behaviors, similar to that which the rostral and caudal motor regions have to learned behavioral sequences of hand movements. 78 Finally, the motor cingulate cortex also sends an overlapping projection to the sensorimotor region of the striatum.71,79 Taken together, the motor and premotor areas (and the frontal eye fields) mediate different aspects of motor behavior, including planning, learning, and execution, which are in turn reflected both anatomically and physiologically in the central and lateral caudate nucleus and in the central, dorsal, and lateral putamen, respectively. The pattern of neuronal discharge in these striatal regions that accompanies these behaviors has been proposed to underlie procedural learning.7,80
