Quick Facts
The postcentral gyrus (aka posterior central gyrus, or ascending parietal gyrus) is located posterior to the central sulcus and is part of the parietal lobe. This part of the parietal cortex is responsible for mapping the sense of touch from the human body. The cortical map itself is a spacial representation of the human body, and is referred to as a sensory homunculus.
