  4. 4. The biology of love <ul><li>Neurological origins of passionate love begin in infancy when infants attach to mother. </li></ul><ul><li>Certain neurotransmitters and hormones involved in pleasure and reward are activated in mother-baby, adult lover, and close friend bonds. </li></ul><ul><li>Endorphins </li></ul><ul><li>Functional MRI’s have shown other neurological similarities. </li></ul><ul><li>Certain parts of the brains light up when people look at pictures of sweethearts and biological children. </li></ul>chapter 14

  9. 9. Arousal and orgasm <ul><li>Freud differentiated between “immature” clitoral orgasms and “mature” vaginal orgasms. </li></ul><ul><li>Kinsey suggested that males and females had similar orgasms but that females were less sexual. </li></ul><ul><li>Masters and Johnson asserted that women’s capacity for sexual responses surpassed men’s. </li></ul><ul><li>But didn’t examine differences based on developmental, experiential, or cultural factors </li></ul>chapter 14
