The adoption by a person’s acceptance of alcohol solutions corresponds to a certain group of nerve cells in the brain, Swedish biologists from the University of Lincoping reported. The results of the study are published in the journal Science Advances.
At the same time, part of people will drink even if common sense suggests that it should not be done. It is specified that in this group of people with an insurmountable burden to alcohol include those who have no explicit alcohol dependence.
In its experiment, scientists used rats prone to compulsive alcohol consumption. At first they were offered to click on the redhead to get a small proportion of alcohol. The experts then changed the conditions: after pressing the rodent lever received a blow to the current. It turned out that most animals stopped doing exercise, but a third of them continued to do this, despite negative consequences.
When scientists analyzed the brain activity of rodents, they found the PKCδ-positive nerve cells in the almond-shaped body of their brain, showing activity before pressing the lever. As the head of the experiment explained, Professor Psychiatry Markus Huelig (Markus Heilig), it is this group of cells that determines the difference between the ability to limit itself and in the inability to stop.
