ABSTRACT
Information in the dorsal stream leaves the visual cortex and goes to the parietal cortex. There is also a projection to areas of the frontal cortex that control movement. The different dichotomy is the distinction between what an object is and where in space that objects the different types of information are processed by two distinct pathways in the visual system. The anatomy of the ventral stream starts with the parvocellular cells of the lateral geniculate nucleus. These project to areas 2 and 3 of visual area V1. From here, information is sent to the blobs and inters blobs of this area. Information about form then goes to area V2 and on to area V4. Information about color goes to area V3 and then to area V4. From area V4, information is sent to the temporal cortex, presumably to allow the information to be integrated with other information processing.
