BrainBeats 作为开源 EEGLAB 插件，用于联合分析 EEG 和心血管信号

Overview

The BrainBeats toolbox is an open-source EEGLAB plugin aimed at facilitating the joint analysis of EEG and cardiovascular (ECG/PPG) signals. This toolbox enhances the study of the brain-heart interplay by providing tools for heartbeat-evoked potential (HEP) assessments and heart artifact extraction from EEG signals, ultimately improving reproducibility and accessibility in research.

Key Study Components

Area of Science

• Neuroscience
• Cardiovascular Research
• Signal Processing

Background

• Historically, the brain and heart systems have been studied separately, limiting understanding of their interactions.
• The BrainBeats toolbox addresses this gap by allowing researchers to explore the dynamic interplay between these systems.
• Insights into cognitive and emotional states' effects on cardiovascular function can lead to new therapeutic interventions.

Purpose of Study

• To provide a standardized tool for multimodal analysis of EEG and cardiovascular signals.
• To enhance understanding of brain-heart interactions and their implications for mental and physical health.
• To improve accessibility and reproducibility in related research.

Methods Used

• The study utilized the BrainBeats toolbox within the EEGLAB framework on MATLAB.
• EEG and cardiovascular signals (both ECG and PPG) were analyzed through graphical interfaces to assess HEP and heart artifacts.
• The protocol included setting paths in MATLAB, loading datasets, and performing feature extraction.
• Critical steps involved changing power line noise settings and validating outputs throughout the analysis.

Main Results

• Notable findings included significant heartbeat-evoked oscillations in the alpha band post-heartbeat.
• Inter-trial coherence analysis indicated no significant phase locking of EEG phase with heartbeats.
• Key outputs also included HRV features and EEG data, revealing important patterns associated with cardiac rhythms.

Conclusions

• The BrainBeats toolbox demonstrates potential for bridging the gap between brain and heart research.
• It enables a more comprehensive understanding of cognitive and emotional influences on cardiovascular health.
• The insights gained can inform future therapeutic strategies and interventions.
