Answer 1

A homunculus is a distorted representation of the human body within the somatosensory cortex, highlighting areas like the hands, face, and tongue as having the largest cortical representation.

Step-by-step explanation:

The unusual drawing of the somatosensory cortex that illustrates how much of the cortex is devoted to various body parts is called a homunculus. The term homunculus comes from Latin, meaning "little man," and portrays the disproportionate amount of somatosensory cortex dedicated to different body parts. According to the sensory homunculus, the locations on the body that have the largest region representing them in the somatosensory cortex are the hands, face, and tongue.
