Abstract

Robust signals of corneal derivation were recorded from the pigeon (a foveate model) in response to alternating gratings. When a rotating windmill-like display was superimposed upon the visual field, there was rate-dependent inhibition of the response to the gratings. Inhibition diminished linearly with grating contrasts (11-40%) and nonlinearly above 50%. The responses to diffuse-light stimuli showed no rate dependence but a predictable, steady reduction at all windmill rates. Rate-dependent inhibition has been reported only in the inner-retinal cells of other animals where intracellular recordings have been made.

摘要

在鸽子(一种具有中央凹的模型)中记录到了对交替光栅的强烈角膜起源信号。当一个类似旋转风车的显示叠加在视野上时,对光栅的反应存在速率依赖性抑制。抑制作用随着光栅对比度(11%-40%)呈线性减弱,在50%以上则呈非线性减弱。对漫射光刺激的反应没有速率依赖性,但在所有风车速率下都有可预测的稳定减弱。速率依赖性抑制仅在其他已进行细胞内记录的动物的视网膜内层细胞中被报道过。
