Abstract

When the two eyes view large, dissimilar patterns that induce binocular rivalry, alternating waves of visibility are experienced as one pattern sweeps the other out of conscious awareness. Here we combine psychophysics with functional magnetic resonance imaging to show tight linkage between dynamics of perceptual waves during rivalry and neural events in human primary visual cortex (V1).

摘要

当两只眼睛观看会引发双眼竞争的大的、不同的图案时,随着一种图案将另一种图案从意识中清除,会体验到可见性的交替波动。在这里,我们将心理物理学与功能磁共振成像相结合,以显示竞争期间感知波动的动态与人类初级视觉皮层(V1)中的神经活动之间的紧密联系。
