The studies are in. What happens to your brain when you watch porn? Conducted by a team from the University of Groningen Medical Center in Netherlands, it shows that watching porn will actually turn off the part of the brain that processes visual stimuli. In women that is.

The study looked at 12 heterosexual premenopausal women, all of whom were on hormonal birth control pills. The researchers looked at their brains using positron electro tomography (PET scans) and the women were shown three different films.

The first was a control about marine life in the Caribbean, the second two were so-called "female friendly" porn.

The results showed that far less blood was sent to the primary visual cortex while they were watching explicit porn. And the same thing happens in the brain when a human conducts a non visual task like memorizing a list of words.

When watching normal, non porn films, extra blood is sent to the visual cortex. So its settled. Porn turns the brain off. Uroneurologist Gert Holsteg, hypothesizes that the results indicate the brain is more focussed on sexual arousal, when watching porn, than on the actual visual processing of the film.
