Fig. 4.

Mean BOLD signals evoked in early visual cortex by the globally coherent and incoherent contexts. Mean parameter estimates from the GLM analysis of all visually responsive voxels (see Materials and methods; averaged across participants) are plotted for regions of interest in early visual cortex. Panels are superimposed on a stimulus schematic indicating the ROI (curve quadrant and distractor quadrant). Only data from experiments when the curve quadrant was the lower-right visual field are shown. Black bars: coherent context. Grey bars: incoherent context. Error bars denote ± 1 standard error of the mean.
