dopamine dysregulation

Watch my new 6-part youtube presentation on porn addiction

Submitted by gary on

I just completed a 6-part, narrated, power point presentation on porn addiction. It covers a lot of ground and explains so much of what we discuss on this site and have written about.
Subjects include - Coolidge effect, dopamine dysregulation, numbed pleasure response, rewiring of the brain, neuroplasticity, reward circuitry, limbic system, what makes Internet porn unique, what is an addiction, rebooting, learning & unlearning, and elk penises.
It was created so that everyone addicted to porn can get the concepts in one place and in a linear and visual format.

The Overeating and Obesity Cycle

Submitted by Marnia on

Here's some more research on the power of natural reinforcers to alter the brain in response to behavior. This time it's research done on humans instead of rats. One can argue that the women who gained weight were for some reason (initially) vulnerable at a brain level. However this research shows that as they continued to overeat, changes continued to occur in their reward circuitry over time - numbing its pleasure response.
