Developmental Trajectories of Delta-Beta EEG Coupling Across Infancy: The Influence of Infant Temperament and Maternal Anxiety Over Time.

ABSTRACT: Coupling, or the correlation, between delta and beta EEG power may underly regulatory processes. Stronger, positive delta-beta coupling is associated with anxiety and fearful temperament, potentially tracking dysregulation. However, most studies have reported on cross-sectional investigations of delta-beta coupling in children. Thus, the normative development of delta-beta coupling remains poorly understood. Here, we leveraged a diverse sample (N = 165) of infants with assessments of EEG, negative affect, and maternal anxiety across 4, 8, 12, 18, and 24 months to model trajectories of delta-beta coupling and associations with infant and maternal traits over time. Multilevel models of delta (1-2.5 Hz) and beta (11-18 Hz) power indicated that delta-beta coupling increased from 8 to 24 months
