Definition

A subdivision of the primate visual system located in the extrastriate cortex in an area sometimes referred to as the parietooccipital area. It plays an important role in directional motion perception in primates.

Current Knowledge

The dorsomedial area (V6) is an extrastriatal area located near the interhemispheric fissure and includes parts of the medial cortex, including the parietooccipital fissure. It is considered to be a node in the dorsal visual pathway. Its functional role in vision is well described in new world monkeys, though its role in man is still not entirely clear. V6 receives input from primary visual cortical areas and contains white matter pathways that are highly myelinated, providing for fast transmission of visual information.

V6 neurons are particularly responsive to the orientation of visual contours and direction of the movement of visual patterns. Topographically, these neurons provide a representation of the entire visual...
