`Good mothering` hardwires infant brain

Washington: A study has revealed that the mother's presence, social interactions and her nurturing role directly moulds the early neural activity and growth of the infant's brain.

The research by the NYU Langone team has shown how such natural, early maternal attachment behaviors, including nesting, nursing, and grooming of pups, impact key stages in postnatal brain development.

The lead study investigator, Emma Sarro, said that these 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 as there are so many factors that go into rearing children.

However, Sarro added that further research is also under way to investigate what other noradrenergic biological mechanisms might also be involved in controlling maternal sensory stimulation of the infant brain.

This study is published in the July 21 edition of the journal Current Biology.
