Long bursts of stimulation applied to the primary motor cortex elicit
A) simple movements of one joint.
B) simple contractions of one muscle.
C) complex natural-looking response sequences.
D) reflexes.
E) either A or B

Question

Quizplus · Accepted Answer

Long bursts of stimulation applied to the primary motor cortex can elicit complex natural-looking response sequences, such as reaching or grasping movements. This is because the primary motor cortex is involved in the planning and execution of complex movements, not just simple ones. Therefore, choice A and B are not sufficient answers. Reflexes are typically simple and automatic responses, so choice D is also not a good answer. Choice E is partially correct, but choice C is a more complete answer.
