Areas 3, 1 & 2 – Primary Somatosensory Cortex

The lateral postcentral gyrus is a prominent structure in the parietal lobe of the human brain. It is the location of the primary somatosensory cortex, the main sensory receptive area for the sense of touch. Like other sensory areas, there is a map of sensory space in this location, called the sensory homunculus.
