Researchers Test Brain Corner Responsible To Adverse To Alcohol


Scientists have come up with a test report of the region of brain that regulates how sensitive a person is to the negative effects of alcohol.

The neuroscientists say the relationship of brain to recreational drugs involves a complex system of reward and punishment. When one sees such drugs, including alcohol, the reward system of the brain is triggered and it releases pleasure-inducing neurotransmitters to enable the feel of consuming more and more.
On the other hand, the adverse effects of the drugs like that of sickness, hangovers and impaired motor function helps in regulating the intake to prevent further consumption of intoxicants that may become a problem.

The research was conducted by the scientists at university of Utah, and upon detailed investigation they found the main area of interest was the region called leteral habenula, which negatively regulates the motivation to consume cocaine and nicotine, and also encourage a person to learn from adverse experiences.

The scientists took a group of rats in their study and inactivated the lateral habenula. It was seen these rats drank 20 percent of more alcohol compared to other rates who were not inactivated. The rats also escalated their drinking faster.

It is said the rates with inactivated lateral habenula failed to know from their negative experiences that the drinks are not to be taken beyond this level.
