Visual Consciousness: The Binocular Rivalry Explosion
A new behavioural technique solves a long-standing puzzle of binocular suppression, demonstrating that adapting reciprocal inhibition governs visual sensitivity and raising key questions about visual awareness.
متن کاملRhythms of Consciousness: Binocular Rivalry Reveals Large-Scale Oscillatory Network Dynamics Mediating Visual Perception
Consciousness has been proposed to emerge from functionally integrated large-scale ensembles of gamma-synchronous neural populations that form and dissolve at a frequency in the theta band. We propose that discrete moments of perceptual experience are implemented by transient gamma-band synchronization of relevant cortical regions, and that disintegration and reintegration of these assemblies i...
متن کاملProbing visual consciousness: rivalry between eyes and images.
During binocular rivalry, one stimulus is visible (dominant), while the other stimulus is invisible (suppressed); after a few seconds, perception reverses. To determine whether these alternations involve competition between the eyes or between the images, we measured suppression depth to monocular probes. We did so in conventional rival stimuli and in rival stimuli swapping between the eyes at ...
متن کاملOlfaction Modulates Visual Perception in Binocular Rivalry
Vision is widely accepted as the dominant sense in larger primates including humans, whereas olfaction is often considered a vestigial sense yielding only obscure object representations [1]. It is well documented that vision drives olfactory perception [2, 3], but there has been little indication that olfaction could modulate visual perception. Here we introduce smells to a well-established vis...
متن کاملPredicting Visual Consciousness Electrophysiologically from Intermittent Binocular Rivalry
PURPOSE We sought brain activity that predicts visual consciousness. METHODS We used electroencephalography (EEG) to measure brain activity to a 1000-ms display of sine-wave gratings, oriented vertically in one eye and horizontally in the other. This display yields binocular rivalry: irregular alternations in visual consciousness between the images viewed by the eyes. We replaced both grating...
