Consciousness correlates with activation of higher visual areas? How do we know monkeys do the task? Catch trials Gamma-distribution Contrast-dependence Problem: what exactly is the task?

τι βρήκανε; και λοιπόν; FFA: fusiform face area, PPA: parahipocampal place area perceived vs. retinal stimulus (dissociation with BR) activation during rivalry equal to non-rivalry playback (fig. 7) BR fully resolved before the FFA and PPA level rivalry + non-rivalry = event related ROI localiser scans = block design event-related averaging (time-locked to perceptual switch) content + duration of percept reflected in fMRI signal measure % signal change with respect to fixation baseline consciousness correlates with activation of higher visual areas
