Abstract

We report a new characteristic of the presaccadic activity of the neurons in the frontal eye field of macaque monkeys. A fraction of neurons exhibited a significant pause in discharge rate preceding the excitatory visual or movement-related response. This pre-excitatory pause, which has been observed in striate and extrastriate visual areas, may represent a resetting of neural activation for detailed visual processing or saccade preparation.

摘要

我们报告了猕猴额叶眼区神经元眼跳前活动的一个新特征。一部分神经元在兴奋性视觉或运动相关反应之前，放电率出现显著停顿。这种兴奋性前停顿，已在纹状和纹状外视觉区域观察到，可能代表了为进行详细视觉处理或眼跳准备而对神经激活的一种重置。
