Overview

An ERP study shows atypical neural responses relate to emotional risk in toddlers born preterm, indicating potential early intervention pathways.

Key Points

  • This research aims to explore how neural responses to facial expressions differ in toddlers born preterm and their implications for emotional risk.
  • Examined 45 toddlers born prematurely aged 15-30 months using EEG to measure event related potentials (ERPs).
  • Analyzed the association between gestational age and ERP responses to dynamic facial expressions.
  • Employed linear mixed-effects models to assess ERP amplitudes and latencies across different groups of preterm infants.
  • Earlier gestational age linked to larger P400 and frontal NC amplitudes in ERP responses.
  • Most premature children showed reduced right-to-left hemispheric differentiation in N290 latency.
  • Source localization identified frontal and temporal regions as key areas related to ERP variability.
