A method for investigating binocular rivalry in real-time with the steady-state VEP

摘要: Under conditions in which the visual system cannot reconcile dissimilar images from two eyes, perception typically alternates between half-images-a process known as binocular rivalry. We report a real-time, steady-state VEP method that is sensitive detector of continuous alternations perceptual dominance across eyes. This works by labelling each half-image with slightly different temporal frequency so record generated can be recovered EEG spectrum analysis. In this way, one track "waxing" and "waning" amplitudes for eye simultaneously during spontaneous rivalry, permitting an analysis relative physiological real-time. Such were clearly observed rivalry (the eyes correlated negatively). contrast, varied either synchronously or randomly when half-images allowed to fuse. The instances evidenced well subjects' dominance. purely electrophysiological appears suitable measuring non-verbal human animal subjects, it does not require active participation them.
