We have compared responses of cat visual cortical cells of area 17 to continuously illuminated moving slits and to moving slits illuminated stroboscopically at different rates (70-2 Hz) using quantitative multihistogram techniques. At strobe rates over 30 Hz response characteristics of cortical cells are almost identical under both conditions, except for a lower response level under stroboscopic illumination. As strobe rates decrease below 30 Hz, direction selectivity and velocity tuning are severely impaired and some cells start responding to the individual strobe flashes rather than to the motion of the slit.
我们使用定量多直方图技术，比较了猫17区视觉皮层细胞对持续照亮的移动狭缝以及以不同频率（70 - 2赫兹）频闪照亮的移动狭缝的反应。在频闪频率超过30赫兹时，两种条件下皮层细胞的反应特性几乎相同，只是在频闪照明下反应水平较低。当频闪频率降至30赫兹以下时，方向选择性和速度调谐会严重受损，一些细胞开始对单个频闪闪光而非狭缝的运动做出反应。
