Abstract: The response to moving light and dark slits was recorded from a total of 94 cells in V1, V2, and V5 (MT) in 9 anesthetized and paralyzed macaque monkeys (M. fascicularis). Using the spatial lag method2, response latencies were calculated for each cell. We obtained median latencies of 85, 96, and 94 ms for cells in areas V1, V2, and V5, respectively. The higher median latencies of V2 and V5 cells compared to V1 are commensurate with later stages of information processing, and are predictable from the anatomy of the interconnections. In addition, a distinct, second population of high-latency cells is present in all 3 regions, but is most abundant in lamina 4 of V5. These may represent either external feedback from other regions or ongoing processing. Extensive overlap of latencies in all 3 regions at both the high and low ends of their respective ranges indicates a considerable degree of parallel interaction between striate and extrastriate cortex.
