Within this review, we provide an overview of the neurobiology of pornography addiction. The review focuses on the basic neurobiology of addiction and studies done on the neurobiology of the internet pornography addiction. This review also highlights the role of dopamine in pornography addiction, the role of certain brain structures as found on MRI studies and the effect of pornography addiction on higher cognitive functions. The review suggests that internet pornography addiction fits into the addiction framework and shares similar basic mechanisms with substance addiction. The review also stresses on the need of future research in this area.
