In this study, we used seed-voxel correlation analysis to investigate resting state (RS) functional connectivity (FC) of the anterior cingulate cortex (ACC) in two groups of patients with multiple sclerosis (MS): a treatment group, performing 12 weeks of cognitive rehabilitation of attention/information processing and executive functions, and a control group. At follow up, increased FC between the ACC, the right middle frontal gyrus and inferior parietal lobe was detected in the treated group, while decreased FC between the ACC, the cerebellum and the middle temporal gyrus was detected in the control group.
