A mother’s love confers measurable brain benefits

This is why so many kids are screwed up.

“According to senior study investigator and neurobiologist Regina Sullivan, PhD, whose previous research in animals showed how maternal interactions influenced gene activity in the infant brain, the latest study offers an even more profound perspective on maternal caregiving.

“Our research shows how in mammals the mother’s sensory stimulation helps sculpt and mold the infant’s growing brain and helps define the role played by ‘nurturing’ in healthy brain development, and offers overall greater insight into what constitutes good mothering,” says Sullivan, a professor at the NYU School of Medicine and its affiliated Nathan S. Kline Institute for Psychiatric Research. “The study also helps explain how differences in the way mothers nurture their young could account, in part, for the wide variation in infant behavior among animals, including people, with similar backgrounds, or in uniform, tightly knit cultures.”

“There are so many factors that go into rearing children,” says lead study investigator Emma Sarro, PhD, a postdoctoral research fellow at NYU Langone. “Our findings will help scientists and clinicians better understand the whole-brain implications of quality interactions and bonding between mothers and infants so closely after birth, and how these biological attachment behaviors frame the brain’s hard wiring.””
