当观察者的两只眼睛受到相互冲突的刺激时，它们就会进入双眼竞争状态，两种可能的感知会交替占据主导地位。我们通过测量人类事件相关脑电位从竞争性刺激到非竞争性刺激的转变，研究了双眼竞争后的神经活动及其时间过程。与感知相容变化和非竞争控制条件相比，当这些变化不引起意识知觉的变化时，它们引起了N1成分的明显减弱和P3峰的延迟和减弱。这些结果表明，人类双眼竞争最迟在眼外视觉区域得到解决。神经报告10:713-716 (C) 1999 Lippincott Williams & Wilkins。
WHEN the two eyes of an observer are exposed to conflicting stimuli, they enter into binocular rivalry and the two possible percepts will alternate in dominance. We investigated neural activity and its time course following binocular rivalry by measuring human event-related brain potentials to transitions from rivalrous to non-rivalrous stimulation. When these changes did not entail a change in conscious perception they elicited a markedly attenuated N1 component and a delayed and attenuated P3 peak as compared to perceptincompatible changes and non-rivalrous control conditions. These results suggest that in humans binocular rivalry is resolved at latest in extrastriate visual areas. NeuroReport 10:713-716 (C) 1999 Lippincott Williams & Wilkins.
