Despite the Fact That the Musculature Represented in the Motor

Essay

Despite the fact that the musculature represented in the motor cortex (Fig. 26.17.B) shows the eyes, movement of the eyes are is not controlled by the motor cortex (but rather, by cranial nerves III, IV and VI). Explain the difference, then, between tracking a fast-moving object vs. one that is moving slowly. In both cases, assume that the object is close enough so that the head must move to keep the object on the retina.
