In this study, we investigated the resting-state fMRI signals of healthy control (HC) participants and patients with Internet addiction disorder (IAD). 3T-fMRI recordings were conducted. The HC group consisted of 21 males (19-24ys) who had a score of Internet addiction test less than 40. The IAD patients were dragonized at Kurihama medical center, consisting of 25 males (13-17ys). We calculated the correlation coefficient for 2492 voxels in a size of 8*8*8mm within the whole brain, excluding the cerebellum. We determined paired regions showing differences in the correlation between the HC and IAD groups. Significant connectivity differences between NC and IAD were found in the regions of pairs nodes including paracentral lobule, precentral gyri, and right temporal areas, suggesting that the functional connectivity was altered, toward deterioration, in the IAD patients. Confounding with age effects is an issue of further study because of large age difference existing between the two groups.
