Abstract

On average, cells in areas 17, 18 or 19 of normal and stroboscopically reared cats respond with equal maximum firing rates to a narrow bar of light whether moving at the optimal velocity in the preferred direction of movement of flashed at the optimal position within the receptive field. Firing rates in the non-preferred direction of movement are much lower, however, suggesting that direction selectivity is mostly based on inhibition.

摘要

平均而言，正常饲养和频闪饲养的猫的17区、18区或19区的细胞，无论光线窄条是在感受野内的最佳位置闪烁，还是沿最佳速度在运动的偏好方向上移动，其最大放电率都相同。然而，在非偏好运动方向上的放电率要低得多，这表明方向选择性主要基于抑制作用。
