Activarea sistemului Mirror-Neuron de către clipurile video erotice prezice gradul de erecție indusă: Un studiu fMRI (2008)

COMMENTS: Mirror neurons are activated when we watch porn videos. This may mean that static pictures, like old Playboys, are far less compelling and addictive than videos. Below is an excerpt about mirror neurons from this site:

“Before the discovery of mirror neurons, scientists generally believed that our brains use logical thought processes to interpret and predict other people’s actions. Now, however, many have come to believe that we understand others not by thinking, but by feeling. For mirror neurons appear to let us “simulate” not just other people’s actions, but the intentions and emotions behind those actions. When you see someone smile, for example, your mirror neurons for smiling fire up, too, creating a sensation in your own mind of the feeling associated with smiling. You don’t have to think about what the other person intends by smiling. You experience the meaning immediately and effortlessly.”

Abstract

Although visually-induced erection is a common occurrence in human male behaviour, the cerebral underpinnings of this response are not well-known. We hypothesized that the magnitude of induced erection would be linearly correlated with the activation of the mirror-neuron system in response to sexually explicit films. When presented with sexual video clips, eight out of ten healthy subjects had an erectile response demonstrated through volumetric penile plethysmography. The level of activation of the left frontal operculum and of the inferior parietal lobules, areas which contain mirror neurons, predicted the magnitude of the erectile response. These results suggest that the response of the mirror-neuron system may not only code for the motor correlates of observed actions, but also for autonomic correlates of these actions.
