The Science of Romance

In humans, there are four tiny areas of the brain that some researchers say form a circuit of love. [Dr. Bianca] Acevedo, who works at the Albert Einstein College of Medicine in New York, is part of a team that has isolated those regions with the unromantic names of ventral tegmental area (VTA), the nucleus accumbens, the ventral pallidum and raphe nucleus.

The hot spot is the teardrop-shaped VTA. When people newly in love were put in a functional magnetic resonance imaging machine and shown pictures of their beloved, the VTA lit up. Same for people still madly in love after 20 years.

The VTA is part of a key reward system in the brain.

“These are cells that make dopamine and send it to different brain regions,” said Helen Fisher, a researcher and professor at Rutgers University. “This part of the system becomes activated because you’re trying to win life’s greatest prize – a mating partner.”
