Pros and cons of sex
- Dynamic changes in nucleus accumbens dopamine efflux during the Coolidge effect in male rats (stimulus properties of a novel receptive female may serve to reinitiate sexual behavior) Also see entire study, with graphs.
Men versus women on sexual brain function- Prominent differences during tactile genital stimulation but not during orgasm (during the sexual act, differential brain responses across genders are principally related to the stimulatory (plateau) phase and not to the orgasmic phase)
Dopamine's role in mating and pair bonding
Hormonal changes when falling in love (Testosterone levels of new lovers come into sync...and diverge again within two years)
Vasopressin performs many tasks in the body. In mating and bonding it is sometimes though of as a counterpart to oxytocin in females.
