While they were both in the psychology department of Stony Brook University, Bianca Acevedo and Arthur Aron scanned the brains of long-married couples who described themselves as still “madly in love.” Staring at a picture of a spouse lit up their reward centers as expected; the same happened with those newly in love (and also with cocaine users). But, in contrast to new sweethearts and cocaine addicts, long-married couples displayed calm in sites associated with fear and anxiety. Also, in the opiate-rich sites linked to pleasure and pain relief, and those affiliated with maternal love, the home fires glowed brightly.
A happy marriage relieves stress and makes one feel as safe as an adored baby. Small wonder “Baby” is a favorite adult endearment. Not that romantic love is an exact copy of the infant bond. One needn’t consciously regard a lover as momlike to profit from the parallels. The body remembers, the brain recycles and restages....
During idylls of safety, when your brain knows you’re with someone you can trust, it needn’t waste precious resources coping with stressors or menace. Instead it may spend its lifeblood learning new things or fine-tuning the process of healing. Its doors of perception swing wide open. The flip side is that, given how vulnerable one then is, love lessons — sweet or villainous — can make a deep impression. Wedded hearts change everything, even the brain.
