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 |
