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.
在9只麻醉并瘫痪的猕猴（食蟹猴）中，从V1、V2和V5（MT）区域的总共94个细胞记录了对移动的明暗条纹的反应。使用空间滞后方法2，计算每个细胞的反应潜伏期。我们分别获得了V1、V2和V5区域细胞的中位潜伏期为85、96和94毫秒。与V1相比，V2和V5细胞较高的中位潜伏期与信息处理的后期阶段相符，并且可以从互连的解剖结构中预测到。此外，在所有3个区域中都存在明显的第二群高潜伏期细胞，但在V5的第4层中最为丰富。这些细胞可能代表来自其他区域的外部反馈或正在进行的处理。在所有3个区域各自范围的高端和低端，潜伏期都有广泛的重叠，这表明纹状皮层和纹外皮层之间存在相当程度的平行相互作用。
