Figure 4.

Increased belief‐related connectivity between OFC and visual cortex V5 in schizophrenia. Schizophrenia patients showed a significantly increased psychophysiological interaction (OFC × belief‐congruent minus belief‐incongruent perceptual switches) compared with healthy controls in right motion‐sensitive visual cortex (t = 3.7, P = 0.03, corrected within V5 ROI). A contralateral cluster showed a similar trend but failed to reach significance after correction for multiple comparisons (T = 2.2, P = 0.02, uncorrected). Axial and sagittal slices show voxels with a significant group difference in the psychophysiological interaction (patients > controls) within the V5 ROI. For display purposes t‐maps are thresholded at P < 0.05, uncorrected. Colour bars indicate t‐values. [Color figure can be viewed at http://wileyonlinelibrary.com]
