Why we we fell in love? Differences between them and they

Recently researchers at the University College of London captured images of brains in love and concluded that at the sight of the beloved, not only are activated parts of the brain, such as the anterior cortex, Cingulate, which also responds to the stimulation of synthetic drugs producing feelings of euphoria, but that areas make social judgments and submit the neighbor to valuation are they turned off, making us "blind" of love. Although we attracted people with features similar to ours, we tend to choose the scent of those who have a different immune system. And until a person is set in another already has built a mental map, a full cast of brain circuits that determine what will make you fall in love one person and not another. Even influences the blood type (A, B, AB, O), as the attraction is often the case with people of the same type.

Attraction: They fall in love by eyes and them, by the ear

In the first stage of love, falling in love, are more involved the eyes of man, the ears of the woman, and smell in both, particularly pheromones, substances that different animals secrete produce modifications in the opposite sex and have to do with attraction. Dancing produces a factory of pheromones, which according to the stage of life in which they are both, it can be given instant attraction ('love at first sight'). After orgasm, the limbic system of the brain releases the hormone oxytocin. According to the expert on the subject at the University of Edinburgh, Gareth Leng, oxytocin helps to forge permanent links between lovers. The hormone acts by changing the connections of the billions of brain circuits. Leng said that buprenorphine strengthens the bond between a mother and her baby, and occurs both during childbirth and orgasm. It makes the couple feel more linked and close emotionally. When it is combined with estrogen, female hormones, women feel loving and conversationalist. But when mixed with male hormones, the testosterones, it can lead to an uncontrollable need to sleep. If you have a sufficient relationship with the same person it is likely that this pump hormones make us lose the head by someone.


From biochemistry, falling in love is explained by the intervention of substances Monoamines "like dopamine, a neurotransmitter and a hormone that is associated with a system of reward and pleasure in the brain, so when the secretamos we feel very well", says Leonardo Palacios Sánchez, neurologist and Dean of the Faculty of Medicine of the Universidad del Rosario. Studies with functional magnetic resonance images allow you to see that when a person in love sees the image of the beloved or hear his name and compares it with a neutral subject, areas of the brain are activated him. This makes "or the girlfriend" to act strange to lose the trial, everything seems perfect; sleep is disturbed him, and although he trasnoche feels not runnig. Experience less pain. Attention is altered, it forgets everything, do what was entrusted to him. This process will sum the neural growth factor substance, and reduces the neurotransmitter serotonin, which makes the person to have thoughts and obsessive behavior on the other.

The narcotic of love

The (ugly) phenylethylamine, amphetamine that segregates the body, is one of the substances involved in falling in love. This compound activates the secretion of dopamine, a neurotransmitter involved in sensations of desire that makes us repeat what gives us pleasure, and produces oxytocin which activates sexual desire. love By flooding the brain of this substance, it responds by secreting dopamine, neurotransmitter responsible for the mechanisms for reinforcement of the brain, the ability of wanting something and repeat behavior that generates pleasure, norepinephrine, and oxytocin, which in addition to stimulate uterine contractions for childbirth and produce milk, is a chemical Messenger of sexual desire, and stimulates the neurotransmitters that originate to falling in love. Such mixture of compounds has lovers remain hours making love and nights talking, tirelessly, which are always excited, needing another as a drug and that their ability to judge it to be reduced to zero.

The substances of the embrace and monogamy

After one to three years, the couple begins to consolidate and brutal production of dopamine, substances that accelerate, falls and couples go to the 'intellective attraction'. One is to the other much more than someone who attracts him physical, sensual and sexually and passes from the stage where is says "I wish you" says that "I love you". Georgina Montemayor, academic Department of Anatomy of the medicine Faculty of the National Autonomous University of Mexico, said that to receive a hug, a handshake or a caress, the brain releases oxytocin, known as the chemical substance of the embrace, which was discovered in 1953. Men and women free it touching, hugging, and it has a maximum at the time of orgasm increase, when it comes to climbing up to 400% above the normal level and makes people adhere. Other substance is vasopressin or 'chemical of monogamy', which increases and makes the link will endure for many years.

Die for love

In spite or "tusa", as Colombians say, are also produced some dramatic changes in the brain that have to do with an area called the anterior Cingulate cortex, which is activated when a person suffers a painful, not just emotional, experience but physical. A dancer who split just before a presentation feels pain multiplied by 20. It is like during the spite, because dopamine is addictive and so people look for it. There is the "love sickness", which is called Tako-Tsubo syndrome. The feeling of 'broken heart' is real and has to do with the neurobiology, but also the feeling of absolute loss of joy. The duration of the "COB" depends on whether the person has good defense mechanisms. If it is mature, it will go forward alone, but it is valid to seek therapeutic help in his friends, his family and why not. It is important to work in the duel and must be resolved before six months. When the rupture has been infidelity hurts more. But now many infidels castle that: "what is mine is a disease". According to Palacios, "there are things that we bring genetically, others are acquired in the middle. "I would keep the optimism that, despite having that gene, if one is truly in love, committed, if the other or the other fills it and you agree that your spirit can overcome genetics". Source:
