THE earliest stages of cortical visual processing in areas VI and V2 of the macaque monkey contain internal subdivisions ('blobs' and 'interblobs' in layer 4B in VI; thin, thick and interstripes in V2) that are selectively interconnected and contain neurons with distinctive visual response properties1-10. Here we use anatomical pathway tracing to demonstrate that higher visual areas, V 4 and the ventral posterior inferotemporal cortex, each contain anatom-ical subdivisions that have distinct input and output projections. These findings, in conjunction with others11-15, suggest that modul-arity and multistream processing within individual cortical areas are widespread features of neocortical organization.
