MOSCOW, October 14 - RIA Novosti . The differences between men and women in response to stress, may be related to the fact that in men present special protein which, under certain conditions blocks the brain chains associated with anxiety states, according to the article published in the journal Cell .
"This is a very unusual phenomenon, as those cells that are responsible for this reaction, are arranged and look the same in the brains of men and women, and are in them in the same amount. It rarely happens that the same cells in completely different ways respond to the same stimuli in the body of individuals of different sexes "- said Nathaniel Heintz (Nathaniel Heintz) from the Rockefeller University in New York (USA).
Heinz and his colleagues came to this conclusion by studying how the brain a few mouse-males and females respond to various external stimuli and molecules hormones inserted into nerve cells genes that allow scientists to "turn on" and "off" neurons using blue pulses Sveta.
Recently, as Heinz says, his group discovered an unusual chain of neurons in the brains of female mice, which respond to oxytocin molecule, a hormone happiness and love. Hormone stimulation of these cells molecules, as shown by further experiments, mice were more sociable makes interaction with males.
A similar chain of nerve cells, according to biologists, is present in the male brain, and scientists became interested to know what functions they perform in their body. When the researchers injected mice oxytocin nose, no visible changes in behavior have occurred.Trying to understand why this is happening, the Heinz team began to expose mice to various tests.
Enable and disable the cells, they suddenly noticed that the woman's "communication center" in the brain of males played a completely different role - its inclusion led to the fact that rodents ceased to feel anxious and worried when they were in a stressful situation. Nothing like that is interesting, did not occur with females, were subjected to the same "execution."
The reason for this, as it turned out after the analysis of the cells, the hormone was CRHBP, which cells produce data in stressful situations. This substance, according to scientists, is blocking the work of another hormone - corticotropin. He is responsible for the beginning of the stress response and is a "trigger" for the assembly of molecules "real" stress signals - kortikotropnogo hormone and cortisol.
Isolation CRHBP oxytocin receptors, as they say, scientists, slows down the entire chain of synthesis of stress hormones, which explains why males and females are much less susceptible to stress than the females, and women, and recover more quickly afterwards.
How to find Heinz and his colleagues, CRHBP does not help women cope with stress for the reason that their body initially produces more corticotropin than a body of men, because of what data the nerve cells and produced them CRHBP can not reduce the concentration of this hormone to an acceptably low level.
In addition to differences in the behavior of women and men, especially in the work of the chain of neurons, scientists say, could explain why some people are more emotional than others, and vice versa.
