| 摘 要： | 用细胞外记录的方法，研究了视觉刺激对清醒猴初级视皮层神经元眼球位置效应的影响，当猴注视电视屏幕上２５个不同位置的小光点时，屏蔽上分别给予两种不同形式的视觉刺激：注视点周围的闪光圆环和感受野内的移动光条。这两种刺激都能增强初级视皮层神经元的眼球位置相关活动，并相应地使受眼球位置调制的神经元的比例明显增加。

| Abstract: | Extracellular recordings were made in the primary visua1 cortex (V1 ) in two awake monkeys to test the influence of visual stimuli on the eye-position related activites of the neurons. While the monkeys gazed on a fixation point (FP) positioned sequentially at different locations on a TV screen, two types of visual stimuli were presented on the same screen: (1) A small light ring flashed repeatedly around the FP or(2) A prefered light bar shifted continuously across the cell' s receptive field (RF).Both stimuli significantly enhanced the eye-position related activities and correspondingly increased the incidence of the eye-position dependent neurons. The results show thatthe integration of information on vision and on eye position may tuke place at quite theearliest stage of the visual cortices. |
