Abstract

Neuronal spike discharges were recorded from the lateral suprasylvian (LS) area while ocular convergence was elicited in five alert cats. Ocular convergence was elicited by presenting a visual target moving in depth. Cats were rewarded for convergence eye movement. In 9 out of 426 cells sampled in the caudal postero-medial LS area, the number of spikes was positively correlated with the peak eye velocities during ocular convergence. Significant correlation was found mostly within 400 ms preceding the moment at which the maximum velocity of ocular convergence was obtained. The result favors the hypothesis that the LS area plays an important role in the integrative control of ocular convergence.

摘要

在五只清醒的猫身上诱发眼会聚时，记录了外侧上薛氏（LS）区的神经元放电。通过呈现一个在深度上移动的视觉目标来诱发眼会聚。猫因会聚眼动而得到奖励。在尾侧后内侧LS区采样的426个细胞中，有9个细胞的放电次数与眼会聚期间的峰值眼速度呈正相关。显著相关性大多出现在获得眼会聚最大速度之前的400毫秒内。该结果支持了LS区在眼会聚的整合控制中起重要作用这一假说。
