Mørch-Johnsen L, et al. - Researchers searched for morphometric correlates of auditory hallucinations in bipolar disorder (BD) by comparing cortical thickness and cortical surface area in bipolar disorder patients with (BD+) and without (BD-) a lifetime history of auditory hallucinations. Findings revealed cortical thickness alterations in both the left Heschl's gyrus [HG] and the superior parietal lobule in association with a lifetime history of auditory hallucinations in BD. Compared to BD-, BD+ showed thicker, rather than thinner cortex.
