Extracellular recordings were carried out in the visual cortex of behaving monkeys trained on a fixation/detection task, during which a target light was displayed stationary or suddenly moving on a tangent translucent screen. The responses of visual cortical cells to fast moving stimuli during steady fixation and those obtained during rapid eye movements (saccades) which moved their receptive field across a stationary stimulus, were studied. Areas V1 and V2 were explored. When tested with rapidly moving stimuli (500 deg/sec) during steady fixation, neurons in each area behaved in almost the same way. About one fourth of them were activated, the remainder showing either no response (little more than a half of them) or a reduction of the spontaneous firing rate. In both areas, some of the neurons activated during steady fixation did not respond or responded very weakly during eye motion at saccadic velocity (500 +/- 50 deg/sec). Neurons of this type, which we refer to as 'real motion' cells, could somehow contribute to the maintenance of visual stability during the execution of large eye movements.
在接受注视/检测任务训练的行为猴子的视觉皮层中进行了细胞外记录，在此任务期间，目标光在一个相切的半透明屏幕上静止显示或突然移动。研究了视觉皮层细胞在稳定注视期间对快速移动刺激的反应，以及在快速眼动（扫视）期间将其感受野移过静止刺激时所获得的反应。对V1和V2区域进行了探索。当在稳定注视期间用快速移动刺激（500度/秒）进行测试时，每个区域的神经元表现几乎相同。其中约四分之一被激活，其余的要么没有反应（超过一半），要么自发放电率降低。在这两个区域中，一些在稳定注视期间被激活的神经元在以扫视速度（500±50度/秒）进行眼动时没有反应或反应非常微弱。我们将这种类型的神经元称为“真实运动”细胞，它们可能以某种方式有助于在进行大幅度眼动时维持视觉稳定性。
