Postcentral gyrus

In neuroanatomy, the postcentral gyrus is a prominent gyrus in the lateral 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.

Structure
The lateral postcentral gyrus is bounded by: • medial longitudinal fissure medially (to the middle) • central sulcus rostrally (in front) • postcentral sulcus caudally (in back) • lateral sulcus inferiorly (underneath) The postcentral gyrus includes Brodmann areas 1, 2, and 3. Brodmann area 1 occupies the apex of the postcentral gyrus. ==See also==
