How does the brain integrate complex and dynamic visual inputs into phenomenologically seamless percepts? Previous results demonstrate that when are organized coherently across space time, they more strongly encoded in feedback-related alpha rhythms, less feedforward-related gamma rhythms. Here, we tested whether this representational shift from feedforward to feedback rhythms is linked phenomenological experience of coherence. In an Electroencephalography (EEG) study, manipulated degree spatiotemporal coherence by presenting two segments same video hemifields, either synchronously or asynchronously (with a delay between segments). We asked participants perceived stimulus as coherent incoherent. When stimuli were presented at perceptual threshold (i.e., was judged 50% times), perception co-varied with coding rhythms: coherent, represented activity; incoherent, activity. Whether input incoherent thus depends on shifts
