Response of 70 neurons in area 17 of the visual cortex to optimal stimuli of different intensity in the receptive field under conditions of photopic adaptation were analyzed in unanesthetized cats. The reaction threshold, differential sensitivity, optimal intensity and the width of the brightness range were estimated. No intensity detectors were found in this area. 70% of neurons studied had inhibitory distortion in the range of their intensity functions. The neurons differed in their threshold reactions by 5-6 orders, in dynamic range--by 3-4 orders, and in differential sensitivity--by 2-3 orders. The visual cortex neurons with receptive fields in central and periphery parts of the visual field had different intensity functions.
在未麻醉的猫身上，分析了视觉皮层17区的70个神经元在明适应条件下对感受野中不同强度最佳刺激的反应。估计了反应阈值、微分敏感性、最佳强度和亮度范围宽度。在该区域未发现强度探测器。所研究的神经元中有70%在其强度函数范围内存在抑制性畸变。这些神经元的阈值反应相差5 - 6个数量级，动态范围相差3 - 4个数量级，微分敏感性相差2 - 3个数量级。在视野中央和周边部分具有感受野的视觉皮层神经元具有不同的强度函数。
