Question

Quizplus · Accepted Answer

This statement is true. The hands and the face have a high degree of representation on both the somatosensory cortex and the primary motor cortex, which means that a large portion of these brain areas are dedicated to processing sensory input and controlling movements from these body parts. This is known as cortical homunculus, where body parts are represented in proportion to their sensitivity and complexity of movement.
