There are several daily behaviors explained by neuroscience that show us the complexity of the human being, there are more and more studies, and more and more advanced, on the biological mechanisms present in the actions, thoughts and feelings of human beings. many mysteries.
In particular, there are certain behaviors that we consider normal, but which, from a physiological point of view, are extremely complex and represent the highest expressions of the human brain, so it is a fascinating subject that has caught the attention of many scientists. .
“Does biology give you a brain?. – Jeffrey Eugenides-
The everyday behaviors explained by neuroscience are not limited to this biological illustration, the human body is biological, but also symbolic, the brain prevents us from being pure anatomy, because it constitutes a very elaborate nerve network, which gives birth to more than pure matter This is clear if we analyze what science has to say in relation to the following behaviors :
Shame is one of the everyday behaviors that neuroscience explains, at least from a physiological point of view, and we say at least?Because so far science hasn’t been able to understand why we’ve been emptied. shame, which is why Darwin called the blush “the most human expression. “
Science says that in the face of a situation of shame the body releases adrenaline, which causes blood vessels to dilate to facilitate blood circulation and oxygen circulation, the veins of the face expand and allow more blood to flow than normal. Appears. From a psychological point of view, this corresponds to the feeling of being trapped in the act.
Kissing is not a universal expression, it is not present in all cultures, although it does in many cultures, some primates, such as chimpanzees and bonobos, also kiss, however, the function that the kiss performs between them is a function of reconciliation . They do not press their lips together or exchange saliva.
As for humans, the subject is very different, male saliva contains a protein called darcin, which depends on testosterone, the presence of this protein allows the woman to identify which male is most likely to reproduce. menstruation and ovulation alter a woman’s breathing. In the kiss, the man picks up these signals and knows when the woman can reproduce.
A study by the Department of Psychology at The University of Lonbeck in Germany attempted to establish which brain mechanisms were part of generous behavior, based on the idea that altruism is not only a product of education, but also corresponds to a biological mechanism.
After conducting a survey of volunteers, it was established that the most generous people have two characteristics: first, they have greater activity in an area known as the temporoparietal splice (TPJ); and second, this area has a strong bond with the striped core, an element relevant to the feeling of happiness. Humans are genetically equipped to be sociable.
Nail-biting is another of the everyday behaviors that explains neuroscience, although perceived as irrational, it is known that up to 30% of the adult population has this type of behavior, among children the percentage is even higher. In principle, this habit is due to a tension release mechanism, which generates a buildup of energy that decreases when nail-biting.
Now, some research on mice has yielded interesting data, after crossing the same maze several times, these animals found a way to cross it and memorized it, so they have always followed the same path through the maze, when this happened, brain waves in the striatum became slower. In other words, the habit calms down, helps regulate the available energy.
There are still many riddles about human crying, tears are another of the everyday behaviors explained by neuroscience, but only partially, first of all, it must be clarified that there are physiological tears and emotional tears, the first are those that appear when, for example, we cut an onion These are linked to moments such as when we are under the influence of certain emotional states.
According to William H. Frey, a biochemist at St. Paul-Ramsey of Minnesota, emotional tears removed certain components such as manganese, potassium chloride, prolactin, endorphins, adenocotropin and leucine-encephalin from the body. By removing these components from the body, the emotional tension decreases. However, Dutch expert Ad Vingerhoets says crying is a way to express helplessness, an instinctive call for help.
The brain remains a mysterious reality on which science is advancing slowly, although many new features have emerged and arise about the everyday behaviors explained by neuroscience, we are still far from having reached a complete understanding of human phenomena.
