Somatosensory cortex

The secondary somatosensory area (S2) is present in Somatosensory cortex is one region of the brain that is truly in touch with the outside world, both figuratively and literally. Information about things that are touched, and what body part is touching them is represented within a structural framework that is somewhat the same across species. The somatosensory cortex is a part of the cerebral cortex and is located in the middle of the brain. This image shows the somatosensory cortex, highlighted in red in the brain.

The somatosensory cortex is a part of the sensory nervous system which helps with the localization of the sensations, as well as the perception of pressure on our skin and body – it’s the part of the brain responsible for the fact that we’re able to distinguish between a 2016-10-19 somatosensory cortex lies in the parietal cortex immediately behind the central sulcus.

This cortex is in charge of processing all bodily sensations. The somatosensory cortex is located within an area of the brain called the postcentral gyrus, a structure that forms a band around the middle of the cerebral cortex, encompassing both hemispheres. The Somatosensory Cortex is an area of the brain, located in the parietal lobe, that processes sensory input from the skin, muscles, and joints. This area detects and interprets information on touch, temperature, pain, and pressure and allows us to perceive the size, shape, and texture of an object via touch. In addition, the somatosensory cortex is responsible for helping us monitor the position of our own body in space.

It lies posterior to the central sulcus.
