The Neurochemistry of Love, Lust, Anger, and Aggression
Passionate Love: Neurochemical Profile
- High densities of dopamine (DA) and norepinephrine (NE), but low levels of serotonin (5-HT).
- Displays subcortical activity in the Ventral Tegmental Area (VTA), caudate nucleus, and putamen.
- Functions on dopaminergic-rich pathways, resulting in brain activation similar to cocaine use. It is rewarding, positive, and motivating.
- In response to seeing a loved one, the VTA uses chemical messengers (dopamine, serotonin, and oxytocin) to send signals to the nucleus accumbens.
