Basic introduction Chinese name: another name of love hormone: oxytocin regulation principle: hormone secretion substances in posterior pituitary gland: overview of love hormone, regulation principle, secretion substances, influencing factors, main components, blood test and love hormone overview. Some people call oxytocin "the hormone of love", which can make mothers breast-feed their babies more intimately and even make couples more satisfied with each other. Oxytocin can not only promote lactation of lactating mothers, but also promote interpersonal communication, such as the connection between mother and child, the trust and generosity between strangers and the intimacy between husband and wife. Oxytocin is therefore called "the hormone of love". Now, some studies show that this hormone may also help people with autism by raising their social awareness. The paper was published in the Proceedings of the National Academy of Sciences. The researchers also said that it is not clear how phenylethylamine regulates the human body, but they can be sure that phenylethylamine is definitely regulating and controlling some physiological and psychological behaviors of men and women in love. For example, when phenylethylamine is secreted the most, love is the most romantic, the relationship between lovers is the closest, and phenylethylamine is at work. 1, Pituitary Hormone The voles injected with this hormone are loyal to their "partners" and prefer physical contact such as hugs and kisses. Before this, there have been many studies and discussions about pituitary hormones. This hormone exists in the brains of mammals and is one of the main driving forces for some species to love each other and kiss their mothers and children. What Gates and Carter want to know is whether hormones in the posterior pituitary gland prompt voles to choose monogamy. It is true that when Carter injected some female mice with this hormone, they were not as picky about mate selection as before, but once they established a relationship, they would be loyal to their husbands and even a little "clingy". The voles injected with this hormone also like kissing, hugging and other physical contact better than those without injection, and turn a blind eye to other voles and deliberately avoid them, which means "I only have eyes for you". More interestingly, when Carter injected these female rats with drugs to reduce pituitary hormone, they immediately abandoned their once beloved partners. In the study of human beings, scholars have found that this hormone is secreted not only by lactating women, but also by men and women during sexual intercourse. In fact, the higher the hormone level in the posterior pituitary gland, the stronger the excitement of both sides. 2, vasopressin, vasopressin makes voles more repulsive to their partners, and even become "jealous." But in the mating behavior of voles, there is war besides love. After mating, the male mouse immediately produces another biological hormone, which turns the male mouse from a passionate lover into a soldier armed to the teeth. He will try his best to keep an eye on his mother mouse for fear that other suitors will rob her, and this suitor often sits in front of their house, showing a dense white tooth. Carter once injected male rats with vasopressin after mating with voles, and soon the anxiety of male rats disappeared, but a small amount of vasopressin could promote male rats to protect their partners more actively. Therefore, pituitary hormones are only one of the directors of vole emotional drama, and there is another one called vasopressin. Both male and female mice have this chemical in their brains, but the content of male mice is higher. Vasopressin also exists in the human brain. Scientists have not confirmed the effect of vasopressin on people. They suspect that this is similar to voles: they secrete during mating, which helps to deepen the intimate relationship between the two sexes, but the role of vasopressin can turn a man into a "jealousy." Carter concluded: "The biochemical processes of human beings and animals (especially monogamy) are probably the same, because this is the most basic function, and they are probably the key factors to promote the combination of the two sexes." Some substances-secreting animals (including people) love cheating so much because they don't secrete vasopressin and pituitary hormones, two "love hormones"? Scientists found that this was not true. It is not only infatuated animals that secrete vasopressin and pituitary hormones that help to increase feelings. Those philandering animals and humans also secrete these substances. So, why on earth are some animals loyal and others heartbreaking? Neuroscientist Thomas Isele studied vasopressin receptors in the posterior lobe of voles and mountain rat, and found that they were distributed in different parts. Hormone receptors of MICROTUS voles are distributed in the pleasure area of brain cells. Mountain rat's hormone receptors are distributed in other areas of the brain. In other words, male voles can remain loyal to their original mates after mating because they feel very happy. But for mountain rat, mating is a very boring but necessary thing. Mating doesn't make them feel happier than scratching. But why are some voles fickle and others loyal to their partners? Further research found that the difference in the number of receptors in the brain led to the emotional difference of each vole. Neuroscientist Larry Young found that some animals have more antidiuretic hormone and pituitary hormone receptors than others. Larry injected a set of genes into the brains of some male voles, which can continuously increase hormone receptors in the posterior pituitary gland. These male mice will become reluctant to be separated from their wives, even if they have never mated. Larry said: "Usually, voles have to be in contact for 24 hours before they can be paired, so the number of hormone receptors can determine whether two voles are still together or apart after mating. Perhaps it is these differences that affect the loyalty of human feelings. " Influencing factors 1. Scientist Fisher speculated that there are many reasons for the occurrence and development of human emotions. * * * can make people distinguish which mating objects are among all sentient beings, and let "a couple continue to associate until sexual behavior happens naturally"; And feelings "can make couples endure each other's shortcomings for a long time and have children with him or her." 2. Studies have proved that love and desire are obviously different for human beings: most of human sexual behaviors are caused by hormones such as testosterone (both men and women), but testosterone can't make people love. Sociologists say that most of our marriage customs are to mediate the tension between love and desire. Pepper said, "Many people long for romance, but most people need loyal and friendly love". 3. Scientists can do more things in emotion besides simply analyzing the biochemistry related to love and loyalty. Scientist Insel is currently studying how to treat "emotional disorders", such as autism, stalking others, intense jealousy and other pathological behaviors. So if one day "loyalty pills" and "exclusive water" appear on the market, you don't have to be surprised. Main ingredients Hormone ingredients: 1, phenylethylamine (phenylethylamine): Love at first sight or long-term love, the feeling of "calling" is the masterpiece of this hormone. The nervous system regulates its secretion level, which is actually a stimulant, which makes people feel extremely excited, energetic, full of confidence and courage. The face is red and the pupils are dilated. Amphetamine-Amphetamine: the main component of * * *, with similar structure. 2. dopamine: It can produce a very happy feeling. The oxytocin it secretes, and the sense of security and satisfaction when hugging can't be separated from it. 3. norepinephrine: vasoconstriction and nerve conduction can cause blood pressure, heartbeat and blood sugar to rise. When your body is full of these substances, it is also the time when you are madly in love. 4. endorphin: The feeling of comfort, warmth, intimacy and calmness after vigorous. Make you like being in love. Some people just can't get enough endorphins to calm themselves down. 5. Vasopressin is the key to control loyalty. Turn feelings into eternity. 6, phenyl ethylamine, regulated by the body's self-regulation ability, this kind of regulation always tries to adjust the body back to the normal state, and the concentration of these substances in the body will gradually decrease. Generally, the peak lasts for six months to four years. 7. Love addicts pursue the ecstasy and madness brought by love, but just like people are resistant to stimulants, when the body is used to a high level of hormone concentration, it cannot feel the impact of * * *. Blood test A pair of British science and technology journalists took blood twice before and after the wedding oath. In the couple's view, the purpose of blood drawing at the wedding is a "more romantic" purpose, that is, to test how the "phenyl ethylamine" that promotes interpersonal intimacy in the body changes before and after they say "I do". The bride Linda Geddes wrote an article "My Happiness Hormone Wedding", which tells the story of this "research" process. Geddes wrote at the beginning of the article that the wedding is about to begin. "But before I put on my wedding dress and become a bride, I have one more thing to do." . She asked a nurse to draw 20 ml of blood from her arm vein with a small needle. Downstairs in the lobby, the groom Nick and 1 1 guests also rolled up their sleeves and collected blood. After the swearing-in ceremony, the couple completed the second blood draw with the guests who had previously received blood draw, and then began to drink champagne, dance and other celebrations. Paul Zach of California Neuroeconomics Research Center took the blood samples back to the United States for blood sample analysis after centrifugal freezing. A month later, he emailed Geddes and Nick about the analysis results. As the couple expected, the content of oxytocin, a hormone that promotes interpersonal intimacy, increased after the wedding vows, indicating that they love each other more after saying "I do". The results of blood sample analysis showed that the content of oxytocin in Gajdys was higher than that in Nick. Zach explained that women are more likely to be emotional and have higher expectations for marriage, and oxytocin in the body increases greatly during the wedding. The increase of oxytocin content in Geddes's mother's body is second only to Gedis among all blood collectors. This shows that the closest relatives are more involved in the wedding than other guests. In addition to oxytocin, Zach also detected the changes of vasopressin, renal epithelial substances, testosterone and other hormones in blood samples, and obtained unexpected findings. The results showed that the contents of stress-related hormones such as renal epithelium in Geddes increased significantly, while those in Nick decreased instead of increasing. This shows that the bride may be under more pressure than the groom at the wedding. In addition, the oxytocin content of some guests who received blood samples also increased, indicating that they were infected by the wedding atmosphere and felt closer to others. This phenomenon shows that the wedding is helpful to enhance the feelings of relatives and new people, which may explain the significance of the existence of the wedding. As Zach said: "We hold weddings because these emotions help to maintain human beings (groups).
