Scientists from the National Institute of Health and Research Center in San Francisco managed by stimulating certain areas of the brain with a laser beam to rid rats from cocaine addiction, and vice versa - to cause drug dependence in healthy rats.

"Vozdeystvovuya prelimbicheskuyu laser light in the region of the prefrontal cortex of the brain, we were able to eliminate kakainovuyu dependence in animals," - said Antonello Bonci (Antonello Bonci), a professor of neurology at Johns Hopkins University (Johns Hopkins University) and scientific director of programs at the National Institute for the Study of drug abuse (National Institute of Drug Abuse).

The study, the results of which are detailed in a recent issue of the journal Nature, showed that the prefrontal cortex plays a key role in the development of cocaine addiction. Experts hope that this effective treatment for drug addiction will soon be tested in humans.

Hitherto, in treatment of cocaine dependence and other people using noninvasive scientists electromagnetic stimulation of the brain, in particular, a technique called transcranial magnetic stimulation. In the new study, the laser was used for the first time.

At present, preparations for clinical trials necessary to find out whether this method in humans.

Bones and his colleagues plan to begin clinical trials in which they will use a new method of laser stimulation of the prefrontal cortex of the brain of people with cocaine dependence, to find out whether you can return the area to normal brain activity and thus help them to avoid taking drugs in the future.
