Porn may be messing with your head

The study, published in JAMA Psychiatry, can't say watching porn caused the decrease in brain matter and activity, however. It's not clear, for example, whether watching porn leads to brain changes or whether people born with certain brain types watch more porn, said Simone Kühn, the study’s lead author from the Max Planck Institute for Human Development in Berlin, in an email. But, she noted, the results provide the first evidence for a link between pornography consumption and reductions in brain size and brain activity in response to sexual stimuli.
