Table 2. Categorical Comparison of rCBF: Control versus Low
The probabilistic threshold used to identify the regions was P = 0.0006 for peak z value and 25 voxels for cluster extension. Cluster extensions are in number of voxels (uniform voxel size of 2 mm). Uncorrected and corrected P values (for multiple comparisons, P < 0.05) correspond to the peak z values. P values at cluster level are corrected for multiple comparison and thresholded at P < 0.05.
* Result is significant corrected for multiple corrections within the volume of predefined structures (threshold, z = 3.2) but not for whole brain volume.
BA = Brodmann area; LPFC = lateral prefrontal cortex; LPi = inferior parietal lobe; SMA = supplementary motor area; GFm = medial frontal gyrus; GTs = superior temporal gyrus; PVG = periventricular grey.
