DEEP

DEEP implements a dual electroencephalography (EEG) hyperscanning pipeline for quantifying inter-brain neural synchronization in dyads during naturalistic social interactions.

Key Features:

• Dual EEG hyperscanning pipeline: Processes simultaneous dual EEG recordings from interacting dyads to enable inter-brain analyses.
• Phase Locking Values (PLVs): Calculates Phase Locking Values (PLVs) as indices of inter-brain phase alignment between dyads.
• Cross-Frequency Phase Locking Values: Computes cross-frequency PLVs to assess phase relationships across different frequency bands between participants.
• Time-frequency responses and EEG power analysis: Performs time-frequency analyses and EEG power estimation to characterize temporal and spectral dynamics within and across participants.
• Control for spurious correlations: Includes scripts to mitigate spurious correlations to distinguish genuine inter-brain synchrony from artifacts.

Scientific Applications:

• Developmental hyperscanning studies: Analyzes neural dynamics in developmental contexts to study social interaction-related synchronization.
• Mother-Infant Interactions: Applied to mother-infant EEG hyperscanning datasets to investigate early caregiver–child neural synchrony.
• Social neuroscience research: Enables investigation of neural mechanisms underlying communication, empathy, and other social behaviors via inter-brain synchrony metrics.

Methodology:

Preprocessing of EEG data, calculation of PLVs and cross-frequency PLVs, time-frequency analyses and EEG power estimation, and application of scripts to control for spurious correlations.
