A new study showed that: people who watch a lot of porn, brain gray matter significantly less than those who do not watch porn.
This article was first published in the JAMA Journal of Psychiatry, the article is not yet say whether porn can cause brain damage, the authors were asked to carry out further research on this topic.
'Max Planck Institute for Human Development' staff in Berlin, Germany, said: "Future studies will focus on the investigation porn sustainable human influence, we will give those who have never seen porn people watch pornographic films, and then as the passage of time, observe the effects of pornographic films produced in them. "
The study enrolled 64 male volunteers between the ages of 21-45, they can be described in pornographic films in the field experience.
Subjects will not immediately be informed about the purpose of the trial, they will not be granted for the time trial will use magnetic resonance imaging measuring instrument (MRI) scans of their brains. They in a telephone interview after the completion of the test, said everyone must accept the test's questions about porn inquiry, which is part of the experiment.
The subjects also filled out questionnaires, contents of the questionnaire is the number of pornographic films they watched, the subjects answered an average of a little more than four hours per week. Experimenters subjects with MRI scans of the brain, but also the yellow pornographic images online to show them.
Experimenter said: "Our results showed that people often watch a small movie less right tail striatal gray mass." Also when the stimulus is stopped when the yellow sheet, MRI show low activity in the brain region is reactivated.
However, "is not in the striatum little person going to see more porn of it," "then, or yellow sheet so that the striatum small"? In the end is a causal relationship between them is a prerequisite for it? These are for further study.
Experimenter said: "The striatum small people need more external stimuli to experience pleasure, so they may need more pornographic films as compensation, which will allow them to see more of the yellow sheet, so we need to do more and more research. "
