Regions of decreased functional connectivity in older individuals with ADHD within the executive control network (IC 6 in Fig. 2). The significant cluster covers parts of the bilateral anterior cingulate cortex and the bilateral paracingulate cortex (cluster size: 493 voxels). The coordinates of the voxel with highest significance are: x = − 2 mm, y = 42 mm, z = − 2 mm (p = 0.004). Brain images are displayed in radiological convention (the right hemisphere appears on the left side of the image).
