Outline of Final Research Achievements |
We investigate the effects of colour perception at the primary visual cortex on subsequent visual areas using chromatic sine wave gratings and the effect of colour on the recognition of emotional faces. 1)Time-frequency analysis conducted the magnetic field responses to sine wave grating, and the main effect of colour was significant in the 20~80 Hz band from 300 ms after stimulus onset in the ventral cortex of V1 to V4. 2) We evaluated the valence of emotion to the coloured emotional face by a psychological experiment. There was no effect of colour on angry faces. Since we have a strong conception that anger is red, it is thought to have been unaffected by other colours.
