COMMENT: Adolescents with internet addiction have decreased gray matter in portions of the frontal cortex. Decreases in size and functioning the frontal cortex are found in all addiction processes. I wonder about the extent of porn use in the Internet addiction group. Another example of a non-drug addiction causing brain changes similar to substance abuse disorders.

The two similarities were: 1) Excessive activation of the reward circuitry we given cues (pictures of food) 2) […]
