The somatosensory cortex is located on the postcentral gyrus in the parietal lobe behind the primary motor cortex. It is involved in somatic sensation, visual stimuli, and movement planning, with different body regions represented across the cortex. The primary somatosensory cortex processes basic sensation while the secondary somatosensory cortex serves as an association area involved in higher functions like memory, spatial processing, and consciousness.

2. LocationThe Primary Somatosensory Cortex is located on the PostcentralGyrus. It is the anterior part of the Parietal Lobe and lies behind the Primary Motor Cortex of the Frontal Lobe.

3. FunctionInvolved in somatic sensation, visual stimuli, and movement planning.Similar to the motor cortex, regions of the somatosensory cortex reflect regions of the body.

4. Those regions that require precise sensation occupy larger areas of the cortex.SubstructuresPosterior to the Primary Somatosensory Cortex lies the Secondary Somatosensory Cortex. This region of the Parietal lobe seems to be serve as an association area for sensory input.It is involved with episodic memory, visuospatial processing, reflections upon self, and aspects of consciousness.
