Electrical activity of a population of visually responsive cells located in the vicinity of a single functionally defined neuron was recorded in the area 18 of the cat's cerebral cortex with a single tungsten microelectrode. The correlograms calculated from the mass activity record showed an existence of a rhythmic neuronal firing with an average interval near to 3 ms. When the system was activated by a visual stimulus, a line at an optimal angle moving in an optimal direction, the rhythmic activity became regular, acquiring an oscillatory sinusoidal character. This rhythmic pattern cannot be easily recognized when the activity of a single neuron is recorded. It is possible that such rhythmic activity involving large numbers of neurons contributes to the recognition of the velocity and position of the visual stimulus.
用单个钨微电极在猫大脑皮层18区记录了位于单个功能定义神经元附近的一群视觉反应细胞的电活动。根据群体活动记录计算出的相关图显示存在有节奏的神经元放电，平均间隔接近3毫秒。当系统由视觉刺激激活时，即一条以最佳角度沿最佳方向移动的线，这种有节奏的活动变得规则，呈现出振荡的正弦特征。当记录单个神经元的活动时，这种有节奏的模式不容易被识别。可能是这种涉及大量神经元的有节奏活动有助于识别视觉刺激的速度和位置。
