The visual cortex of the brain is the part of the cerebral cortex responsible for processing visual information. This article addresses the ventral/dorsal model of the visual cortex.Another model for the perceptual/conceptual neuropsychological model of the visual cortex was studied by Raftopolous. The ventral stream begins with V1, goes through visual area V2, then through visual area V4, and to the inferior temporal cortex (IP cortex). 2  The ventral stream, sometimes called the What Pathway, is associated with form recognition and object representation. 3  It is also associated with storage of long-term memory.
