“Once you fall in love with somebody, once they trigger the brain system for falling in love, love is blind, no question about that,” said Fisher, who recently wrote Why Him? Why Her?, which explores the neurological underpinning of romance.
A 2005 study by Rutgers University biological anthropologist Helen Fisher and colleagues examined the fMRI brain scans of 17 men and women who reported being truly, madly in love. Each of the images showed the same activity in the brain’s reward system as that which occurs in the brain of a cocaine addict.
Fisher’s research suggests an explosive, heart-pounding first kiss can ignite that blinding neurological love reaction, activating the dopamine reward system and setting off an addictive response to one’s beloved.
