Orientation-channel outputs in V1. (A) Illustration of the three ROI locations (Upper-Stim, AM path, Lower-Stim). (B–D) Estimated relative BOLD responses across the eight orientation channels in the Upper-Stim (B), AM-path (C), and Lower-Stim (D) ROIs in V1 for inward/vertical (red) and outward/horizontal (blue) during AM (left column) and Flicker (right column). (E) Channel responses of the AM-path ROI during AM and Flicker, shifted to presumed interpolated orientation and averaged across inward/vertical and outward/horizontal conditions.
