This chapter focuses on the role of the motor cortex in locomotor coordination. The motor cortex does not play any significant role in the production of the basic locomotor pattern in the cat. This was demonstrated by the fact that the mesencephalic cat is capable of ‘simple’ locomotion which is of walking and running in a straight line on a flat surface. This situation strongly contrasts to that in man and other primates, where even ‘simple’ locomotion is very severely disrupted by motor cortex lesions. Neurons of the motor cortex giving rise to the pyramidal tract and projecting to the contralateral fore limb controller can be found in area 4 of the cortex, in its forelimb zone. The motor cortex does not play any significant role in the control of ‘simple’ locomotion generated by the automatic control system, but nevertheless plays a decisive role in the control of visually induced gait modifications.
