A Multimodal Analysis Toolbox of EEG-fNIRS Fusion for Naked Eye 3D Vision Training in Adolescent Myopic Patients

The growing issue of adolescent myopia is mostly addressed through eye-focused methods, overlooking brain function's role. This study developed a toolbox using synchronized EEG and fNIRS to analyze brain activity in adolescents during 2D and 3D visual training. The system integrates data collection, preprocessing, feature extraction, and visualization, capturing metrics like power spectral density, correlation, phase locking, and hemoglobin levels. It is easy to use, employs simple algorithms, and offers clear visuals, helping to understand the impact of visual training on brain function.
