Functional Areas of the Cerebral Cortex Cortex divided into regions based on function (Brodmann) Somatosensory Area (postcentral gyrus) Somatosensory Association Area Shape, texture, relative orientations of body segments, etc. Memory storage for comparison of sensory information Primary Motor Area (precentral gyrus) Voluntary contraction of specific muscles or muscle groups Coding of force and direction of movement Important for generation of skilled and accurate movements Premotor and Supplementary Motor Areas “Memory banks” for learned activities Communicate w/ Primary Motor Area to generate learned, complex, sequential activities Contraction of specific muscles in a specific sequence Writing, walking, etc.
