Evaluation of EEG pre-processing and source localization in ecological research.

ABSTRACT:

Introduction

Electroencephalography (EEG) source localization (SL) has shown potential for various applications, from epilepsy and seizure focus localization to psychiatric disorder evaluation. However, questions remain about its neurophysiological plausibility in real-world settings where only EEG signals are available without subject-specific anatomical information. This study investigates whether established pre-processing and source localization methods can produce neurophysiologically plausible activation patterns when applied to naturalistic EEG data without structural magnetic resonance imaging (MRI) or digitized electrode positions.

Methods

Proven methods are aggregated into an end-to-end pipeline that includes automatic pre-processing, eLORETA for source estimation,
