Wang, et al. (2015) proved that among people with internet gaming disorder GMV (Gray Matter Volume) of the bilateral anterior cingulate cortex (ACC), precuneus, supplementary motor area (SMA), superior parietal cortex, left dorsal lateral prefrontal cortex (DLPFC), left insula, and bilateral cerebellum decreased in the IGD participants compared with healthy controls. Is it the same with internet porn addicts?

  • $\begingroup$ What makes you ask this question specifically? I.e., why porn addiction specifically, and not "train enthusiasts" or any other thing? $\endgroup$
