The co-ordinates of the peak in the MNI system are shown. A threshold of P < 0.001 (uncorrected) with a liberal extent threshold of 100 contiguous voxels was set for displayed data.

BA, Broadmann area; L, left; R, right; +, positive correlation; −, negative correlation.

^aSignificant positive correlation in the ROI analysis with a FWE correction for multiple comparisons (P < 0.05).

^bSignificant negative correlation in the whole brain analysis with a FWE correction for multiple comparisons (P < 0.05).

^cNearest cortical gray matter.
