Skin-to-skin Contact in Neonatal Intensive Care Unit (NICU), Caregiving Touch and Neural Correlates of Slow Stroking Touch in Preterm Infants

Preterm (PT) infants spend their first weeks of life in Neonatal Intensive Care Unit (NICU) where receive little affective physical contact, which plays a crucial role in brain development. Evidence indicates that skin-to-skin contact (SSC) has a positive effect on infants' neurophysiological and behavioral adjustment to postnatal life. Moreover, caregiving touch during early interactions is related to sensitive caregiving behavior, which in turn is associated with brain connectivity in full-term (FT) infants. Despite the importance of both SSC and caregiving touch for infant development little is known about the neural correlates of early physical contact in PT infants. Using MRI the project aims to investigate the association between brain responses to gentle skin stroking at 2 months examining the effects of: (1) the birth status (PT vs. FT); (2) the duration of SSC in NICU; (3) the caregiving touch in the home environment and during mother-infant interaction. The investigators hypothesized: (1) differences in the brain responses in the above mentioned ROIs to gentle skin stroking, a type of tactile stimulus associated with affectionate touch and social interaction26, between FT infants and PT infants: (2) that above mentioned putative differences would be mitigate by duration of SSC during the NICU in PT infants; (3) an association between CT/sensitive caregiving behaviors both in the home environment and during face-to-face interaction and brain response in the above mentioned ROIs to gentle skin stroking in PT and FT infants.
