Scientists also believe that the disappearance of thorns with penis strengthened monogamous relationship. Men began to receive pleasure from sex that made them stick to favorite partners. Another key step   the evolution of man   It was the development of a larger brain. Alas, it is not only made people smarter, but also led to a greater number of cases of brain tumors.

Harmful alcohol is good for the brain ...

It turns out that the effect of alcohol may even be beneficial for our brain, as scientists have found. It contributes to the activation of the learning process.

Scientists from the University of Texas found that if one part of the brain alcohol   cripples, the second, on the contrary, effects of alcohol It stimulates. And this is an area that is responsible for the learning process. So who use alcohol   sometimes people are better able to learn and remember new information.

These findings sound a bit strange, considering the traditional stereotype of what a drunk person is not able to do anything to remember. But neurobiologist Hitoshi Morikawa, who led the study, says that view is mistaken.

"Usually when talking about learning and memory, we mean the conscious memory, - says Dr. Morikawa. - Alcohol   It inhibits our ability to keep in mind these pieces of information, such as names of colleagues in the office, or the value of some words or even the location of the machine you are parked somewhere. But on a subconscious level, it helps to learn and remember, increasing the capacity of the brain, its ability to absorb new information. "

According to Morikawa, alcoholics do not become dependent on the pleasure that they allegedly experienced after drinking, and on the set of behavioral, psychological and physiological guidelines, evolving under the influence of alcohol. This substance affect the release of the brain Dopamine Which is "the hormone of happiness." However, Dr. Morikawa said that Dopamine   properly called "the hormone of training."

These studies published in Journal of Neuroscience. Its main idea is that alcohol can store new information and learning, because in this moment the man is good. And the brain sends a signal to fix this state, to repeat it in the future. However, it is fixed and the information received.
