Question 3

What is the sensory homunculus?

Accepted Answer

The sensory homunculus is a representation of the maplike coding of touch sensations in primary somatosensory cortex. Adjacent regions of the skin are processed by adjacent regions of cortex, resulting in somatotopic mapping. Some regions of the skin (such as the lips, hands, and face) occupy larger regions of cortex than other regions (such as the forearms, back, and upper legs), meaning that the somatosensory map of the body in cortex is distorted. These distortions are often visualized by creating a sensory homunculus that depicts the human body in the same proportions as the amount of cortex they occupy.
