COMMENTS: Delta FosB is one the primary molecules of addiction. It rises, or accumulates, during an addiction process, reinforcing addictive behavior and rewiring of the brain. It rises whether the addiction is chemical or behavioral. This study shows that it accumulates during sexual activity and consumption of sugar. Researchers also found that sexual activity increased the consumption of sugar. Delta FosB may be involved in one addiction reinforcing another addiction. The question is – how does “over consumption” of porn affect Delta FosB?

COMMENTS: Delta FosB is a marker for all addictions, both behavioral and chemical. As this molecule increases in the reward circuit so do addictive behaviors. It’s one of the molecules involved in neuroplastic changes. This experiment shows that it increases with sexual experience, similarly to how it does with drug addictions. In the experiment they employed genetic engineering to increase its levels beyond “normal”. This resulted in enhanced facilitation of sexual activity. We think this happens with porn addiction.

COMMENTS: Study shows neuroplastic and behavioral changes in reward circuit can arise from sexual activity. These include the growth of neurons branches and stronger reaction to drugs. As usual, natural reinforcers and drugs have similar effects on the brain. I don’t know what to make of the key observation that these changes only occurred after a period of abstinence.

Getting help for issues related to excessive porn use is a fine idea. However, many therapists have no conception of how addictive today’s hyperstimulating Internet porn is. Many were trained when static, softcore Playboy was porn, and before the recent brain science that is helping to explain the close parallels between extremely stimulating substances and […]

COMMENTS: It’s food, but it’s a natural reinforcer, like sexual stimuli. This research demonstrates once again that binge patterns with natural reinforcers alter the reward/motivation pathways. Binge patterns in food and gambling have been shown to lower dopamine (D2) receptors. The numbed pleasure response. This leads to a craving for more dopamine stimulating stuff – […]

COMMENTS: Basic premise is that addictions hijacks the pair bonding mechanisms shared by the reward circuitry. Porn addiction therefore likely affects the pair-bonding mechanisms in our brains.
