Which of these is love? Thousands of answers have been offered—but surprisingly few by biologists, including brain scientists. While scientists regard other complex emotional states such as depression, anxiety, or fear as complex, but not unfathomable, love is relegated to the poets and songsters.
Certainly such love can be a joyous state, but it is also capable of producing deeply disturbing, even dangerous results. At least 25 percent of homicides in the United States involve spouses, sexual partners, or sexual rivals.
Each year, some one million American women are followed and harassed by rejected lovers;men are stalked by former partners; and approximately 1.
In fact, male sexual jealousy is the foremost cause of wife battering in cultures worldwide. Husbands, although to a lesser degree, are physically abused by wives. Love is a powerful force; the vast majority of Americans marry.
But the divorce rate in Midsummer mind and impulsiveness physical attraction United States is expected to reach 67 percent in the next decade. Currently, some 80 percent of divorced men and 72 percent of divorced women remarry; but 54 percent and 61 percent, respectively, divorce again.
High divorce and remarriage rates are seen in many other cultures, as well. It is time to investigate the biology of this bittersweet experience we call love. The sex drive evolved to motivate individuals to seek sexual union with any appropriate partner.
In humans, attraction is also associated with feelings of exhilaration, intrusive thinking about the beloved, and the craving for emotional union. Attraction, I hypothesize, is associated in the brain primarily with high levels of the neurotransmitters dopamine and norepinephrine and with low levels of serotonin.
In humans, attachment is also characterized by feelings of calm, security, social comfort, and emotional union. Attachment is associated in the brain primarily with the neuropeptides oxytocin and vasopressin. For each system, the neural circuits can be expected to vary from one species to the next, among individuals within a species, and over the life of an individual.
The three emotion systems also act in concert with one another and with other bodily systems. For example, a person may begin a sexual liaison merely for sexual pleasure, then become romantically involved with this sexual partner.
He can become deeply attached to this partner, too, and these enhanced feelings of attachment can be explained biologically.
After orgasm, levels of vasopressin rise in men; levels of oxytocin rise in women. These hormones are known to cause attachment, and probably contribute to the feelings of closeness after sexual intercourse. The three emotion systems can act independently, as well. Individuals in approximately 90 percent of bird species form seasonal or lifelong pair bonds, becoming attached and rearing their offspring together.
Likewise, men and women can express deep attachment for a long-term spouse or mate at the same time they express attraction for someone else, and also while they feel the sex drive in reaction to situations unrelated to either partner. The independence of these emotion systems may have evolved among our ancestors to enable males and females to take advantage of several mating strategies simultaneously.
They could also practice polygamy if the opportunity arose. What is the biology of these emotion systems?
Why did they evolve in humans? To what extent do they control our lives? How should we use this information in the practice of medicine and the law? Scientists have long regarded that itch as a distinct emotion system that is innate and common to all birds and mammals.
Moreover, they have long understood at least the basic neuroanatomy and physiology of the libido, agreeing that it is predominantly associated with the androgens in both men and women.
The estrogens also play substantial roles in the sex drive in many mammals, but only a secondary role in humans. This helps to stimulate the release of estrogen and contributes to triggering sexual behavior. In the prairie vole, attraction is a brief, spontaneous, chemically induced, excitatory reaction that initiates sexual desire, sexual physiology, and sexual behavior.
