Objective: Our aim was to detect weather the functional connectivity between the orbitofrontal cortex(OFC) and other brain regions were impaired in type 2 diabetes mellitus(T2DM). Materials and Methods: Conventional magnetic resonance imaging(MRI) and blood oxygen level dependent resting-state functional MRI were obtained from 27 diabetic patients without cerebrovascular diseases on imaging, and from 21 age-matched healthy volunteers. The functional connectivity between the bilateral OFC and other voxels of...
