WebPrimary Visual Cortex (V1) The visual cortex is subdivided into a number of separate and distinct regions called visual cortical areas. Later in the semester we will discuss how these different cortical areas are identified and what their functions are. For now, we will concentrate only on the primary visual cortex (also called V1, shown in blue). WebThe cerebral cortex is common to all mammals. While different regions of the cerebral cortex specialize in processing disparate signals, e.g. sensory coding, motor output, decision making, it is striking that the fundamental structure of the cortex is conserved across these regions.
