The Internet Addiction Level on Resting-state Brain Connectivity

As internet has become more and more popular, the number of people using the internet excessively increases, and so do the cyberspace interactions in the worldwide countries in recent years. Therefore, the population with internet addiction (IA) may potentially increase. The internet addiction is currently becoming a serious mental health problem. However, the mechanism remains unclear. The aim of this study was to apply functional connectivity resting-state functional magnetic resonance imaging (MRI) to find out brain regions of IA. Twenty-seven college students (15 females, 12 males) were recruited to receive functional MRI data acquisition during resting state. Ten brain regions (five in each hemisphere) that related to addiction were selected as seed regions of interest (ROI). In the attempt to assess the relationship between the addiction and the internet, we conducted correlations by functional connective activity and the Chen Internet Addiction Scale (CIAS). We found that the connectivity with ROIs was positively correlated with CIAS scores in the medial frontal gyrus, precentral gyrus, and cingulate gyrus; and was negatively correlated with the superior frontal gyrus. Our findings suggested that these brain areas may underlie the functional connectivity of IA.
