Ventral Stream

The ventral stream is the area of the cerebral cortex which runs from the occipital lobe to the temporal lobe. The ventral stream is connected to the medial temporal lobe, which stores long-term memories, the limbic system, and the dorsal stream, which deals with object locations and motion. It is responsible for visual perception and object recognition. The ventral stream receives its main input from the parvocellular layer of the lateral geniculate nucleus of the thalamus. These neurons project to V1 sublayers 4Cß, 4A, 3B and 2/3a successively.
