ASD Entrainment Analysis Code

Overview

This repository contains MATLAB code for preprocessing and analyzing EEG and behavioral data from a study on cortical entrainment in children with Autism Spectrum Disorder (ASD) and typically developing (TD) peers. The codes were used for the study published in: "Not Just Noise: Impaired Oscillatory Entrainment Reflects Reduced Temporal Flexibility in Autism". doi: https://doi.org/10.1101/2025.07.02.662876

Structure

• preprocessing/: Preprocessing script (Preprocess_EEG_All.m) for EEG data.
• analysis/: Scripts for ERP, frequency analysis, phase-behavior coupling, TRF models, and EEG-clinical correlations.
• params/: Parameter definition files for different components.
• triggers/: Trigger extraction scripts.
• layout/: EEG layout file (64_lay.mat).
• docs/: Original Readme and related documentation.

Main Scripts

1. Preprocess_EEG_All.m — EEG preprocessing using FieldTrip.
2. Run_Entrainment_Analyses.m — Calls functions for:
   • ERP analysis
   • Time-frequency and phase-locking analyses
   • Inactive mode
   • Behavior–EEG phase coupling
   • Temporal Response Function (TRF) modeling
   • Correlation with clinical measures

Dependencies

• FieldTrip toolbox (required for all preprocessing analyses)
