Postcentral gyrus

Recommended video: Lateral views of the brain [19:38]
Structures seen on the lateral view of the brain.

The postcentral gyrus forms the primary somatosensory cortex (Brodmann's areas 3,1,2). It is located on the parietal lobe, immediately posterior to the central sulcus and anterior to the postcentral sulcus. 

The postcentral gyrus receives and integrates sensory information relating to touch, pain, temperature, vibration, proprioception and movement. Each postcentral gyrus contains a topographical map of the body parts from the contralateral half of the body, known as the sensory homunculus. Blood supply to the postcentral gyrus is via the anterior and middle cerebral arteries.

Terminology English: Postcentral gyrus
Latin: Gyrus postcentralis
Definition Gyrus of the parietal lobe that is the site of the primary somatosensory cortex
Location Parietal lobe, between the central and postcentral sulci
