| Outline of Final Research Achievements |
We studied brain responses under binocular rivalry to clarify the temporal dynamics of visual perception. Binocular rivalry is a visual phenomena which causes temporally random perceptual alternation by presenting two different images to each eye. Since recording of brain responses usually requires several tens of iterations, and is not suitable to record such a temporally random responses, we developed a new method called 'phase template analysis'. The new method enabled a one-shot recording of the brain responses under binocular rivalry, and clarified the temporal process of the visual perception. The method also applied to develop a brain machine interface (BMI), resulting a biped robot controlled by brain responses recording with electroencephalogram (EEG).
