Three-dimensional visualization of the cerebral cortex based on scanned human data. The cerebral cortex, the outermost portion of the brain, can be divided into regions depending on function. Depicted here is the primary somatosensory cortex, which is dedicated to perceiving the general sense of touch and receiving signals related to pressure and temperature from receptors in the skin. This region also receives signals and processes information from specialized skeletal muscle receptors called proprioceptors. Proprioceptors sense muscle movements and positioning of the body.
