p032fig01.21 At least three parallel visual cortical streams respond to visual inputs that reach the retina.  Two parvocellular streams process visual surfaces (blob stream) and visual boundaries (interblob stream).  The magnocellular stream processes visual motion.<BR>||  [Retina, LGNs, V[1,2,3,4], MT] to [What- inferotemporal areas, Where- parietal areas]: visual parallel streams [2x blob, 1x bound]
