| Outline of Final Research Achievements |
Interactions of feed forward and feed back signals in human visual cortex was studied by using psychophysics and functional brain imaging techniques. The interactions of color and luminance signal in visual motion was examined by functional MRI and we observed the interaction takes place in wide range of visual area. Also, we investigated the representation of color information in human brain by using functional brain imaging and psychophysical techniques. We reported that categorical color representation has been obtained in the brain of pre-lingual infants (5-7mo) by brain activity recording by near infrared spectroscopy. Also we observed the evolution of color category in the last 30 years in Japanese, revealed by applying an analysis by clustering algorithm to psychophysically recorded data of color categories.
