Outline of Final Research Achievements

To identify "face areas" in rodents, we recorded micro-electrogram (micro-ECoG) from wide cortical areas including occipital visual areas and temporal areas. We found visual form dependent micro-ECoG signals in the temporal two regions (TeA and PRh) among three candidates of "face areas" in rodents. Also we combined micro-ECoG technique and optogenetics as a preparation to photo-mainpulation of the image processing in rodents, In this study, we found a spectral anisotropy in propagation of photo-evoked local field potentials (LFPs)
