Neurons in the superior colliculus, striate cortex, frontal eye fields, and posterior parietal cortex of the monkey respond to visual stimuli. Many of these cells discharge more intensely to a stimulus when it is to be the target for a saccadic eye movement than when fixation is maintained. We have demonstrated that such enhancement of the visual response is also present for cells in prestriate cortex. The prestriate effect is a modulation of the visual response and not a concomitant of oculomotor activity. It is present for eye movements away from as well as into the visual receptive field and is thus similar to that seen in striate cortex and different from that studied in the superior colliculus, frontal eye fields, and posterior parietal cortex. The visual responses of many prestriate cells habituate with repeated stimulation. When the monkey makes saccadic eye movements to a stimulus that is eliciting only a habituated response, the enhancement acts as a dishabituation which persists throughout the eye movement trials.
猴子上丘、纹状皮层、额叶眼区和后顶叶皮层中的神经元对视觉刺激有反应。当刺激将成为眼球快速运动的目标时，这些细胞中的许多对刺激的放电比保持注视时更为强烈。我们已经证明，这种视觉反应的增强在纹前皮层的细胞中也存在。纹前效应是视觉反应的一种调制，而不是眼动活动的伴随现象。它在眼球移出以及移入视觉感受野时都存在，因此与纹状皮层中所见的情况相似，而与在上丘、额叶眼区和后顶叶皮层中所研究的情况不同。许多纹前细胞的视觉反应会随着重复刺激而产生习惯化。当猴子对仅引发习惯化反应的刺激进行眼球快速运动时，这种增强作用就会起到去习惯化的作用，并且在整个眼动试验过程中持续存在。
