In this study we examined the impact of the environmental enrichment of preterm newborns with music on auditory cortex functional connectivity. A group of preterm infants listened to music from 33 weeks gestational age until term equivalent age. Two control groups were used: preterm and full-term infants without music. Auditory cortex functional connectivity with cerebral regions known to be implicated in tempo and familiarity processing were identified for preterm newborns that had music training during their stay in the NICU using Psychophysiological Interaction (PPI) analyses. Our results suggest that music training during hospitalization can modify functional connectivity in the newborn brain.
