Sex and money do not excite the brain the same way

Our brains do not mix sex and money. At least to some degree. A team of researchers led by Jean-Claude Dreher, Centre for Cognitive Neuroscience in Lyon (CNRS / Université Claude Bernard Lyon) has indeed shown that these pleasures are largely treated in two distinct areas of the orbitofrontal cortex , an area above the eyes, the anterior and ventral brain. This discovery, published Wednesday in The Journal of Neuroscience, should help better understand certain diseases such as addiction to gambling.

Until now, neurobiologists knew that a single circuit called "reward" or "subjective experience of pleasure" (food, sex, money...). This is the network of dopamine neurons located in the "reptilian" in our brain, also involved in addiction to certain drugs like cocaine.

But all the good feelings are not equal. Several levels of complexity separating archaic pleasures arising from the innate satisfaction of physiological needs (eating, drinking, having sex...) and more sophisticated pleasures (money, power, seduction, love, knowledge) that are the order of the acquis. Hence the assumption that these "rewards" primary "or" secondary "seek parallel because of their peculiarities, the brain areas distinct," says the CNRS in a statement.

This finding should help better understand certain diseases such as addiction to gambling.
