drug addiction treatment
Scientific discovery may contribute to the treatment of drug addiction
Scientists in Chile to the discovery in the brains of mice that they say may help in the treatment of drug addiction and alleviate the side effects of some medicines.
Scientists said the Pontifical Catholic University in Santiago, they have identified an area of the brain, the cerebral cortex isolated .. .. Play an important role in the cravings of drug abuse.
Shown in laboratory testing on mice addicted to amphetamine stimulant drugs that disrupt the activity of the isolated cerebral cortex by injecting a drug to stop the activity of the brain cells of rats did not show any signs of addiction.
When was the revitalization of the cerebral cortex isolated rats again showed signs of the strong desire in the abuse of amphetamine, according to research published in Friday's Science magazine.
Turrialba, "Fernando is one of the researchers:" This shows us that this region of the brain dealing with information on the cases of the functional body and may guide behavior. "
In a second experiment rats injected group Turrialba Ithiam of drug used to treat mental illness with side effects including anxiety and colic enteric.
When the work was disrupted cerebral cortex isolated rats did not show any signs of concern or colic. When re-activated rat lay on the fractions showing signs of confusion and inertia.
The scientists said there is still a need to know a lot about the cerebral cortex of isolated and do not know how he would react in the event of disruption of the human cerebral cortex, especially for a long time. The tests on rats, approximately 20 minutes.
Turrialba, said at a news conference in Santiago, "is certainly one of the problems is that if the information dealing with the cerebral cortex of the body, what happens to that information when to disable it for a long time. Do the wishes of the other will lose?. This is what we need to consider that now."
