This neuroscience video explains the structure and function of the primary somatosensory cortex, located in the postcentral gyrus of the cerebral cortex. The resource describes how the somatosensory cortex processes touch, proprioception, pain, and temperature information, and explores the roles of areas 3a, 3b, 1, and 2 as well as somatotopic organization within the brain.
