Dorsal (left of vertical, dotted line) and ventral (right of vertical, dotted line) streams constitute separate but interconnected pathways through occipital, parietal and temporal extrastriate visual cortex (rectangular boundaries). Vertical position indicates the hierarchical relationship between areas. Interconnections between streams can be found at essentially every level of the hierarchy. For simplicity, not all areas have been included and only those cross-stream connections mentioned in the text have been drawn. Dorsal and ventral processing streams subserve different behavioural goals, with the dorsal stream aimed at the visual control of skilled actions and the ventral stream aimed at object recognition. The very same sensory cues, such as motion, disparity and shape are processed along both processing streams, but within each stream distinct computations are performed on these same cues in order to support different behavioural goals.
