A and B: Activations of hypothesized regions of interest were derived using the small volume correction tool in SPM8, restricted to anatomical borders defined by a manually segmented MNI brain. Peak voxel activations were significant at p<.05, FWE-corrected.
A) Male psychosis cases (PSY) showed significant hyperactivity compared to male controls in right hypothalamus (HYPO) and anterior cingulate cortex (ACC), and hypoactivity in left hypothalamus (HYPO).
B) Female cases showed hyperactivity in subcortical arousal regions, and hypoactivity in medial prefrontal cortex (mPFC) by FWE-correction and orbitofrontal cortex (not shown here, given trend-level significance).
