| Outline of Final Research Achievements |
The purpose of the present research was to reveal neural mechanisms underlying surround modulation in visual recognition, which focused on the information flow in the visual cortex. We confirmed, by using the optical imaging based on intrinsic signals, that the surround modulation is strong in the cortical area corresponding to the peripheral visual field. In the electrophysiological experiment, we developed a system for analyzing correlations of neuronal activities between different recording sites. The time lags of the correlations suggest the information flow that underlies surround modulation in visual recognition.
