Dorsal Stream

The dorsal stream is the cerebral cortex area which begins in the occipital lobe, where the primary visual cortex is located, and ends in the parietal lobe. The dorsal stream processes spatial information as it is involved in spatial awareness, recognizing where objects are in space, and guidance of actions. The dorsal stream is essential for the perception and interpretation of spatial relationships, accurate body image, and the learning of tasks involving coordination of the body in space. It is interconnected with the parallel ventral stream which runs downward from V1 into the temporal lobe.
