Where is the Postcentral gyrus located and what is its function?

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.

Just so, where is the Precentral gyrus located and what is its function?

The precentral gyrus is the anatomical location of the primary motor cortex, which is responsible for controlling voluntary motor movement on the body's contralateral side. The primary motor cortex is topographically organized and creates a somatotropic map.

Also Know, where are the Precentral and Postcentral gyri located? Structure. The precentral gyrus lies in front of the postcentral gyrus - mostly on the lateral (convex) side of each cerebral hemisphere - from which it is separated by the central sulcus. Its anterior border is represented by the precentral sulcus, while inferiorly it borders to the lateral sulcus (Sylvian fissure).

Also know, what happens if the Postcentral gyrus is damaged?

Damage to the postcentral gyrus of the parietal lobe, the dorsal columns, or the dorsal root ganglion may produce a loss of proprioception, astereognosis, loss of vibratory sense, and loss of two-point discrimination in the trunk or extremities.

What is another name for Postcentral gyrus?

Acronym: PoG. The term postcentral gyrus refers to the convolution of cerebral cortex immediately caudal to the central sulcus, which separates it from the precentral gyrus in humans ( Carpenter-1983 ) and macaques ( Martin-2000 ). Defined by dissection, it is located at the rostral extreme of the parietal lobe.
