Question

Electrophysiological cell-recording studies have indicated that the _______ may be especially important in the control of internally guided motor sequences, whereas the _______ may be especially important in the control of externally guided motor sequences. A. supplementary motor cortex; premotor cortex B. premotor cortex; supplementary motor cortex C. cerebellum; basal ganglia D. basal ganglia; cerebellum

Answer 1

Answer:

A. supplementary motor cortex; premotor cortex

Explanation:

The supplementary motor cortex, also known as the supplementary motor area (SMA), is an area of the cerebral cortex located anterior to the premotor cortex. This area (SMA) is involved in the execution of complex and rapid sequential movements (e.g., typing). Moreover, the premotor cortex is an area of the motor cortex located between the primary motor cortex and the prefrontal cortex. This area (premotor cortex) is activated during motor tasks including, among others, spatial and sensory guidance of movement.
