28 Μαρ 2024 · 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.
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.
24 Ιουλ 2023 · The postcentral gyrus is on the lateral surface of the parietal lobes between the central sulcus and postcentral sulcus. The postcentral gyrus contains the primary somatosensory cortex, a significant brain region responsible for proprioception.
The postcentral gyrus is a region in the brain that is responsible for processing general somatic sensation. It is divided into four areas and has been found to be involved in processing vestibular information, particularly in the areas known as area2v and area3a.
The primary motor and sensory cortices occupy the pericentral region of the brain, which consists of 2 parallel gyri: the precentral gyrus (preCG) and postcentral gyrus (postCG), which are separated by the central sulcus (CS) (Fig. 1).
30 Οκτ 2023 · Primary somatosensory cortex (or Postcentral gyrus) – this is numbered rostral to caudal as 3,1,2. This region is associated with several senses, such as the ones for: This are is also known as the primary motor cortex (or Precentral gyrus) (may possibly include part of Area 6).
The postcentral gyrus is immediately posterior to the central sulcus, behind and parallel to the motor strip. It corresponds to the primary somatosensory cortex (BA 3, 1 and 2).
