The question what is love, sets people at all times. Passionate feelings were studied by philosophers, psychologists, chemists, biologists and other scientists therefore it is possible to explain what is love from the scientific point of view.
On a tomography of a brain of the person in love it is visible that it excited the zones responsible for the system of rewards. It is explained by effect of hormone of dopamine which causes feeling of pleasure. So the brain reacts to strong narcotic substance – cocaine. At the same time at the beginning of emergence of feeling the level of dopamine increases very strongly, and then falls below usual, because of it there can be a depression. As love feelings are similar on impact on cocaine, unfortunate love it is possible to cure. It becomes as well as in a case with drug addiction: from human life all reminders and incentives clean up, and the empty space is filled with something with new, for example, next hobby or an interesting hobby. At animals who connect themselves by the long relations the biologists allocate stages of desire, hobby and attachment in their union. Desire is explained by basic requirements, hobby is called fixing on a concrete object, and thanks to attachment the animals have a strong communication when they are ready to breed and grow up posterity throughout a long time with one individual. The love from the scientific point of view at people is similar to hobby at animals. It appeared for the purpose of reproduction and helps to save efforts, not to waste the energy, and to try to obtain only one partner. It is considered that the feeling of love lasts from 1.5 to 3 years, and further it is replaced by attachment, mutual respect, a habit. Such term gives a guarantee of participation of the father in the most hard time of education of the child. In certain cases, for example, at unrequited love, separation, strong love feelings can longer last. Not for nothing it is considered that the love also is blind. The German scientists found out that at the person in love the brain zones which are responsible for rational thinking and negative emotions are disconnected. At lovers the serotonin level strongly goes down, the control system is disconnected. Because of such chemical changes in an organism some people go for crimes, suicides therefore some scientists incline to a thought that it is necessary to treat for unfortunate feelings tablets. Treatment has to be directed to increase in amount of serotonin in an organism, modern antideressant successfully cope with it. Strong changes in a surrounding situation can save the dying-away love. In response to them the brain receives the raised dose of the same dopamine therefore appointments in romantic atmosphere, rest together can save the collapsing relations. The love from the scientific point of view at representatives of a different floor strongly differs. The man really is visual as at the lover the activity of those parts of a cerebral cortex which are responsible for sight increases. And here at women the love is connected with memory therefore she remembers behavior of the partner, analyzes the obtained information and draws conclusions about a possibility of further creation of the relations.
