Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Signal Processing

Background:

  • Event-related potentials (ERPs) derived from electroencephalography (EEG) are crucial for understanding brain function.
  • The clinical application of EEG and ERPs is hindered by custom coding requirements, parameter tracking issues, and diverse commercial tools.

Purpose of the Study:

  • To introduce EPAT, an open-source, user-friendly MATLAB toolbox designed to streamline EEG data preprocessing and analysis.
  • To provide researchers and clinicians with accessible tools for advanced EEG and related neurophysiological data processing.

Main Methods:

  • EPAT offers EEGLAB-based template pipelines for multi-processing of EEG, magnetoencephalography, and polysomnogram data.
  • The toolbox was evaluated by participants across 14 indicators, with satisfaction analyzed using statistical tests.

Main Results:

  • EPAT facilitates EEG signal browsing, preprocessing, power spectrum analysis, independent component analysis, and time-frequency analysis.
  • The toolbox supports ERP waveform plotting and scalp voltage topological analysis.
  • A graphical user interface enables users without programming experience to perform complex analyses.

Conclusions:

  • The EPAT toolbox simplifies complex EEG data analysis, making advanced techniques accessible to a wider range of users.
  • The release of EPAT is expected to advance EEG methodology and facilitate its translation into clinical studies.
