The responses of visual cortical neurons to patterned visual stimuli were studied in squirrel Sciurus vulgaris. The direction selective, orientation-selective and non-selective neurons were observed. Most direction-selective and non-selective neurons were sensitive to high speeds of stimulus movement--hundreds deg/s. The direction-selective neurons exhibited their selectivity at such high speeds in spite of the short time of the stimulus movement through the receptive field. Orientation-selective neurons (with simple or complex receptive fields) were sensitive to lower speeds of the stimulus movement (tens deg/s). Some mechanisms of the properties described are discussed.
在松鼠（Sciurus vulgaris）中研究了视觉皮层神经元对有图案视觉刺激的反应。观察到了方向选择性、方位选择性和非选择性神经元。大多数方向选择性和非选择性神经元对高速刺激运动敏感——每秒数百度。尽管刺激在感受野中移动的时间很短，但方向选择性神经元在如此高的速度下仍表现出其选择性。方位选择性神经元（具有简单或复杂感受野）对较低速度的刺激运动（每秒数十度）敏感。讨论了所描述特性的一些机制。
