EEGAgent: A Unified Framework for Automated EEG Analysis Using Large Language Models
This work addresses the need for scalable and generalizable EEG analysis in clinical and cognitive research, though it appears incremental as it builds on existing LLM and tool-based methods.
The authors tackled the problem of limited utility in EEG analysis due to task-specific models by introducing EEGAgent, a unified framework using large language models to automate multi-task EEG analysis, achieving flexible and interpretable results on public datasets.
Scalable and generalizable analysis of brain activity is essential for advancing both clinical diagnostics and cognitive research. Electroencephalography (EEG), a non-invasive modality with high temporal resolution, has been widely used for brain states analysis. However, most existing EEG models are usually tailored for individual specific tasks, limiting their utility in realistic scenarios where EEG analysis often involves multi-task and continuous reasoning. In this work, we introduce EEGAgent, a general-purpose framework that leverages large language models (LLMs) to schedule and plan multiple tools to automatically complete EEG-related tasks. EEGAgent is capable of performing the key functions: EEG basic information perception, spatiotemporal EEG exploration, EEG event detection, interaction with users, and EEG report generation. To realize these capabilities, we design a toolbox composed of different tools for EEG preprocessing, feature extraction, event detection, etc. These capabilities were evaluated on public datasets, and our EEGAgent can support flexible and interpretable EEG analysis, highlighting its potential for real-world clinical applications.
