Areas with higher functional connectivity to the bilateral superior parietal lobe in primary insomnia patients compared to healthy controls. Areas of greater functional connectivity in patients include the right pars triangularis (inferior frontal gyrus/Broca’s area, thin blue arrow), right insular cortex (thick blue arrow), right anterior cingulate cortex (thin red arrow), and left ventral posterior cingulate cortex (thick red arrow) (all P < 0.01).
