The neural mechanisms of visual perception

Dr. Logothetis was recognized for his work on the neural basis of visual perception, especially binary rivalry. His laboratory demonstrated that the perceptual alternations during binocular rivalry (BR) are likely to have the same neural origin as those experienced when viewing ambiguous figures, such as depth or figure-ground reversals. By studying the neural events underlying the periods of awareness and phenomenal suppression of a visual pattern during BR, it is possible to understand the neural basis of perceptual multistability that, in turn, is known to reflect the neural processes involved in grouping and image segmentation. Insights from these experiments promise to improve our understanding of visual awareness.
