FIGURE 9-18 Charting the Visual Streams The dorsal stream, which controls visual action (top), begins in region V1 and flows through V2 to the other occipital areas and finally to the parietal cortex, ending in area PG. The ventral stream, which controls object recognition (bottom), begins in region V1 and flows through V2 to the other occipital areas and finally to the temporal cortex, ending in area TE. Information from the blobs and interblobs in V1 flows to the thick, thin, and pale zones of V2 and then to regions V3 and V4 to form the ventral stream. Information in the thick and pale zones goes to regions V3A and V5 to form the dorsal stream.
