Biologists have identified a group of nerve cells in the human brain responsible for making decisions about drinking alcohol.

In the journal Science Advances, the results of studies were published. Swedish biologists identified a group of nerve cells in the human brain responsible for making decisions about drinking alcohol. These cells can work even when common sense suggests that you do not need to drink alcohol.

It is specified that scientists from the University of Linkoping, led by Professor of psychiatry Markus Heilig, conducted neurobiological studies on rats.

Before the experiment, the scientists conducted a sample of those animals that are more prone to drinking alcohol; after that, they began to study the features of neural signals. At first, the rats could get alcohol by simply pressing a certain button, and then the task became more complicated. Along with alcohol, the animals received an electric discharge.

As a result of the experiment, scientists concluded that about a third of the animals continued to press the button, even despite the potential threat to life in the form of electric shocks.

“We found a small group of nerve cells in the brain. She defined the difference between the ability to limit yourself and the inability to stop. We had no idea that such a small group of nerve cells could play such a crucial role in behavior,” Professor Heilig added.
