Is porn poison for the brain?

Just this morning, a current Yale student sent me this fascinating TEDx video, featuring a talk by physiologist Gary Wilson, host of www.yourbrainonporn.com. According to the video description, Wilson’s research “arose in response to a growing demand for solid scientific information by heavy Internet erotica users experiencing perplexing, unexpected effects: escalation to more extreme material, concentration difficulties, sexual performance problems, radical changes in sexual tastes, social anxiety, irritability, inability to stop, and obsessive-compulsive symptoms.”

The video lasts about 15 min, but you can catch the main drift by watching only the first 5.
