Discrete Stochastic Process of the Brain Estimated by Psychophysical Measurement of Ambiguous Figure Perception

Abstract

Understanding perceptual consciousness is one of the most important problems of the contemporary neuroscience. Because sensory information is inevitably ambiguous, it is to be clarified how the brain selects and constructs a certain interpretation of the sensory information. Such typical phenomena are figure perception such as the Necker cube perception and binocular rivalry, both of which provide different conscious percepts during observation of the same visual stimulus and spontaneous alternations between the possible percepts. The present article explains the recent research progress on the brain regions associated with binocular rivalry and common dynamical properties to these kinds of ambiguous perception.
