In addition, the posterior parietal areas have rather consistently been shown to be correlated with intelligence together with other less consistent findings across the brain (Jung and Haier 2007), which may suggest the importance of the fronto-parietal areas and the associated functional network in intelligence (Jung and Haier 2007).

Neil Malamuth at the University of California, Los Angeles has carried out numerous studies examining porn and sexual violence, including one involving 300 men, and concluded that men who arealready sexually aggressive and consume a lot of sexually aggressive pornography are more likely to commit a sexually aggressive act.

If there is a periorgasmic period, then Results are shown with P < 0.0025 uncorrected for visualization purposes.
