Average fMRI time courses for retinotopic regions corresponding to the blank gap in areas V1 (a) and V2 (b), plotted as a function of grating orientation and attentional task (n = 8). Both V1 and V2 showed significantly greater responses to the vertical phantom condition (solid lines) than to the horizontal no-phantom condition (dashed lines) during the 12-s stimulus period (gray inset), regardless of whether subjects had to attend to the peripheral gratings (black lines) or to the central letters (gray lines). Side error bars indicate the average ±1 s.e.m. of all data points shown.
