Maternal chemosignals enhance infant-adult brain-to-brain synchrony.Maternal body odors serve as important safety-promoting and social recognition signals, but their role in human brain maturation is largely unknown.  Utilizing ecological paradigms and dual- electroencephalography recording, we examined the effects of maternal chemosignals on brain-to-brain synchrony during infant-mother and infant-stranger interactions with and without the presence of maternal body odors.  Infant-mother interaction elicited greater brain-to-brain synchrony; however, maternal chemosignals attenuated this difference.  Infants exhibited more social attention, positive arousal, and safety/approach behaviors in the maternal chemosignals condition, which augmented infant-stranger neural synchrony.
