Regions of interest (ROIs), for a typical example subject, visualized on a flattened representation of the subject’s occipital lobe. (A) Target-related activity. Activity corresponding to retinotopic location of the target, averaged across 3 localizer runs. Dark gray corresponds to sulci. Light gray corresponds to gyri. Red patches correspond to statistically significant activity (see Materials and Methods). Blue outline, V1 target ROI. Green outlines, V2 target ROI. Purple outlines, V3 target ROI. (B) Mask-relate activity. Activity evoked by mask-only trials during the main experiment (same format as panel A).
