When ambiguous visual stimuli are presented to the eyes, conscious perception can spontaneously alternate across the competing interpretations - which was known as bistable perception. The spontaneous alternation of perception might indicate a connection between bistable perception and the dynamic interaction of brain networks. Here, we hypothesized that individual differences in perceptual dynamics may be reflected in dynamics of spontaneous neural activities. To test this idea, we investigated the relationship between the percept duration and the reconfiguration patterns of dynamic brain networks as measured by the functional connectivity (FC) during the resting state. Firstly, we found that individual difference of percept duration is associated with the temporal variability of the brain regions which were previously reported in studies of bistable perception, including anterior cingulate cortex (ACC), dorsal medial prefrontal cortex (DMPFC), dorsal lateral prefrontal cortex (DLPFC), superior parietal lobule (SPL), inferior parietal lobule (IPL), precuneus, insula, and V5. Secondly, there is a positive relationship between the temporal variability within the frontal-parietal network (FPN) and the percept duration. Thirdly, our results indicated that individual difference of bistable perception was related to the dynamic interaction between large-scale functional networks including default mode network (DMN), FPN, cingulo-opercular network (CON), dorsal attention network (DAN), salience network (SN), memory retrieval network (MRN). Altogether, our results demonstrated that inter-individual variability in bistable perception was associated with dynamic coupling of brain regions and networks involved in primary visual processing, spatial attention, and cognitive control.

脑网络的时间变异性预测双稳态知觉的个体差异。

当模糊的视觉刺激呈现给眼睛时，意识感知可以在竞争性解释之间自发交替-这就是双稳态感知。知觉的自发改变可能表明双稳态知觉与大脑网络的动态相互作用之间存在联系。在这里，我们假设知觉动力学的个体差异可能反映在自发神经活动的动力学中。为了验证这一想法，我们研究了静息状态下感知持续时间与动态大脑网络重构模式之间的关系，该关系通过功能连接性（FC）进行了测量。首先，我们发现，感知持续时间的个体差异与大脑区域的时间变异性有关，而双稳态感知研究先前已报道过这些区域，包括前扣带回皮层（ACC），背侧前额叶皮层（DMPFC），背外侧前额叶皮层（DLPFC） ），顶叶小叶（SPL），顶叶小叶（IPL），早孕，胰岛和V5。其次，额顶网络（FPN）内的时间变异性与感知持续时间之间存在正相关关系。第三，我们的结果表明，双稳态感知的个体差异与大规模功能网络之间的动态交互有关，这些功能网络包括默认模式网络（DMN），FPN，扣带-操作网络（CON），背注意力网络（DAN），显着网络（SN），内存检索网络（MRN）。总之，我们的结果表明，双稳态知觉的个体间差异与参与主要视觉处理，空间注意力和认知控制的大脑区域和网络的动态耦合有关。
