当模糊的视觉刺激有多种解释时，人类的感知可以在它们之间交替，产生感知多稳定性。平均而言，在开关之间，个体之间的稳定感知持续时间存在很大差异，但这种感知动态个体差异的潜在神经基础仍然不清楚。在这里，我们表明，在一个广泛研究的多稳态范例-双眼竞争-知觉稳定性的个人预测的频率范围内的α（7-13赫兹）的神经振荡。我们的研究结果表明，修改模型的竞争，将神经振荡的影响知觉交替，并提出了一个共同的因素可能会影响动态在许多神经过程的可能性。
When ambiguous visual stimuli have multiple interpretations, human perception can alternate between them, producing perceptual multistability. There is a large variation between individuals in how long stable percepts endure, on average, between switches, but the underlying neural basis of this individual difference in perceptual dynamics remains obscure. Here, we show that in one widely studied multistable paradigm-binocular rivalry-perceptual stability in individuals is predicted by the frequency of their neural oscillations within the alpha range (7-13 Hz). Our results suggest revising models of rivalry to incorporate effects of neural oscillations on perceptual alternations, and raise the possibility that a common factor may influence dynamics in many neural processes.
