Human Reproductive System
- Erogenous zones are areas of the body that are sensitive to sexual stimulation
- The human sexual response has psychological and physiological bases, and is driven by libido (sex drive)
Brain's Role in Love and Sex
- The cerebral cortex is involved in higher-order thinking, such as language and judgment
- The ventral tegmental area is part of the brain's reward system and is active when we fall in love
- The basal ganglia promote attachment, and the angular gyrus is involved in the mirror neuron system, which helps us anticipate the actions of a loved one
- The limbic system is the "seat of emotions", and the hypothalamus is involved in sexual arousal, hormone balance, and blood vessel constriction and dilation
Love and the Brain
- Cortisol levels increase during the initial phase of romantic love, leading to depleted serotonin levels and intrusive, preoccupying thoughts
- Dopamine activates the reward circuit, making love a pleasurable experience, and enhances the release of testosterone
- Oxytocin is the "love hormone", deepening feelings of attachment and making couples feel close to one another
- Vasopressin is linked to long-term relationships and plays a role in defensive behaviors such as mate guarding
- Norepinephrine is a stimulant that causes individuals to feel alert and attentive to their partner
Three Components of Love

Sexual Response Cycle
- The excitement phase involves increased heart rate, blood pressure, and muscle tension, as well as physical changes in the genitals
