当单一的物理刺激导致两个或更多个自发切换（反向）的不同感知时，就会发生多稳态感知。先前的ERP研究报道了与知觉逆转相关的逆转负性和晚期正性成分。本研究的目的是本地化的逆转ERP组件的神经发生器，以评估他们的对应关系与以前的功能磁共振成像结果，并更好地了解其功能意义。一个内克尔型刺激提出了短暂的时间间隔，而受试者表示他们的看法。局部自回归平均源分析和偶极子模型表明，反转负波的源位于下枕颞叶皮层。晚期阳性成分的发生器估计位于颞叶下部和上级顶叶区域。
Multistable perception occurs when a single physical stimulus leads to two or more distinct percepts that spontaneously switch (reverse). Previous ERP studies have reported reversal negativities and late positive components associated with perceptual reversals. The goal of the current study was to localize the neural generators of the reversal ERP components in order to evaluate their correspondence with previous fMRI results and to better understand their functional significance. A Necker-type stimulus was presented for brief intervals while subjects indicated their perceptions. Local auto-regressive average source analyses and dipole modeling indicated that sources for the reversal negativity were located in inferior occipital-temporal cortex. Generators of the late positive component were estimated to reside in inferior temporal and superior parietal regions.
