Facilitating early parent-infant emotional connection improves cortical networks in preterm infants

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatrics

Background:

• Preterm birth can negatively impact early brain development and cortical organization.
• Environmental factors play a crucial role in neurodevelopmental outcomes.
• The need for interventions to support brain development in preterm infants is critical.

Purpose of the Study:

• To investigate if a multimodal environmental enrichment, specifically the Family Nurture Intervention (FNI), can improve cortical activity network development in preterm infants.
• To examine the effects of FNI on functional cortico-cortical connectivity at term age.
• To correlate network connectivity with later neurocognitive performance.

Main Methods:

• A randomized controlled trial involving preterm infants.
• High-density electroencephalography (hd-EEG) recordings at term age.
• Analysis of frequency-specific functional cortico-cortical connectivity.

Main Results:

• FNI demonstrated significant large-scale, frequency-specific network effects, particularly in the alpha frequency band.
• Enhanced connectivity was observed in fronto-central cortical regions.
• Connectivity strength in the FNI group was comparable to healthy term-born infants and superior to infants receiving standard care.

Conclusions:

• Biologically driven environmental enrichment, such as facilitated mother-infant connection through FNI, can improve preterm neurodevelopment.
• Early facilitation of direct human connection positively impacts cortical network organization.
• FNI offers a promising approach to enhance neurodevelopmental care for preterm infants.
