The somatosensory cortex is a part of your brain that receives and interprets sensory data from all throughout your body. Somaesthetic location and corporeal sensory area are two more names for the somatosensory cortex. Let’s take a closer look at the sensory cortex.

This portion of the brain is responsible for receiving sensory information from the body and processing it so that necessary activities can be initiated. To deal with a certain issue, such activities are required. It gathers sensations of touch, pain, and vibration from all parts of the body.

We will undoubtedly investigate the somatosensory cortex in depth in this post. We’ll look at its physical features, as well as its location and blood supply. We’ll go over how the somatosensory cortex is important for processing sensory information in depth.


Sensory Cortex Anatomy


To know the somatosensory cortex’s composition, we must first recognize that it is divided into two valuable components:


The primary sensory cortex, also known as the somatosensory cortex, is located in the frontal lobe of the brain (S1).


Cortex or second somatosensory location (S2).


Location of the Sensory Cortex


The forebrain contains the somatosensory cortex. The parietal lobe contains it.


The postcentral gyrus on the lateral side and the posterior section of the paracentral gyrus on the medial surface of the analytical hemisphere house the primary somatosensory region (S1).


The notable arm or leg of the posterior section of the lateral crack contains the secondary somatosensory site (S2) (a crevice in the cerebral hemispheres that divides the frontal and parietal wattles from the temporal lobe).


Fibrous projections


Somatosensory Cortex Primary (S1).


Forecast fibres are obtained from the thalamus’s forward posterior lateral and forward posterior median cores by the primary somatosensory region. These cores also receive fibers from the contralateral half of the body in the form of the median, trigeminal, and spine lemnisci.


At the somesthetic association point, the fibres from the first somatosensory cortex terminate.


Somatosensory Cortex No. 2 (S2).


The extra somatosensory region receives bilateral fibers from all across the body. However, the neural connections of this component are poorly understood. The majority of the threads in the extra area are assumed to originate from the primary somatosensory site.


Somatosensory Cortex Blood Supply


The medial cerebral artery provides vascular flow to many major somatosensory locations (S1) and secondary somatosensory areas (S2). The cerebral hemispheres’ lateral surfaces are then supplied by this artery.


The part of the major somatosensory site on the cerebral hemisphere’s medial surface. It is also supplied with the help of the anterior analytical artery.


The internal carotid artery includes both of these arteries.


The somatosensory cortex’s blood eventually empties into the premium sagittal sinus.




The somatosensory area is divided into two halves, as previously stated. The primary somatosensory location and the secondary somatosensory location are the two somatosensory locations. This department’s determining factor is that it is unique. As a result, distinct spatial orientations of numerous bodily parts are seen in both zones. This perspective has been debated in the context of Body Representation.

The Main Somatosensory Location (S1) is quite localized. The second section (S2), on the other hand, has awful localisation. As a result, the additional area’s (S2) functions are not recognized. As a result, we’ll focus on the components of the important somatosensory area (S1).


Sensation Localization


This is most likely the somatosensory cortex’s most important feature. It is also responsible for the distinct localization of diverse sensations that occur throughout the body. For example, the somatosensory cortex, specifically region S1, is responsible for pain, touch, tingling, temperature level, and other senses.




The somatosensory cortex is a section of the brain that collects and analyzes sensory information from all around the body. It is split into two sections:


Somatosensory location of importance (S1).


The second somatosensory site (S2).


The somatosensory cortex is located in the wattle of the parietal lobe.


The postcentral gyrus and the paracentral gyrus both contain the primary somatosensory region (S1).


In the vicinity of the lateral fracture lies the secondary somatosensory area (S2).


The contralateral half of the body provides input to the primary somatosensory region (S1). As a result, the entire body is represented as an inverted homunculus, complete with lips and head. Furthermore, they can be found in the lowermost half, as well as the uppermost medial part, which includes the foot, legs, and rectal area.
