Neurons in the lateral intraparietal area (LIP) of the monkey represent salient stimuli. They respond to recently flashed stimuli that enter their receptive fields by virtue of saccades better than they respond to stable, behaviorally irrelevant stimuli brought into their receptive fields by saccades. They respond transiently to abrupt motion onsets, but have no directional selectivity. They respond to stable stimuli that are the targets for saccadic eye movements, but far less before the same saccades without stimuli. LIP is important in the attentional mechanisms preceding the choice of saccade target rather than in the intention to generate the saccade itself.
猴子顶叶内侧面区域(LIP)中的神经元代表显著刺激。它们对通过扫视进入其感受野的近期闪现刺激的反应,比对通过扫视进入其感受野的稳定、行为上无关刺激的反应更好。它们对突然的运动起始有瞬时反应,但没有方向选择性。它们对作为眼跳运动目标的稳定刺激有反应,但在没有刺激的相同眼跳之前反应要少得多。LIP在选择眼跳目标之前的注意力机制中很重要,而不是在产生眼跳本身的意图中。
