| Research Abstract |
To reveal visual cortical processes underlying visual awareness for colored patterns, a series of fMRI experiments were conducted. First, human visual areas were localized for 16 subjects by retinotopy measurements and novel multi-subjects maps of visual areas were constructed. Second, response characteristics of lower visual areas for invisible pattern were revealed by fMRI during continuous flush suppression. Finally, optimal spatial frequency of three types of color signals(luminance, red/green, and blue/yellow opponent signals) was determined for each visual area.
