Explainable AI (XAI) for EEG Analysis: A Survey on Recent Trends and Advancements
This survey provides a comprehensive analysis of the latest trends and advancements in XAI for EEG analysis. It highlights that while AI models show significant potential, their black-box nature hinders clinical adoption. XAI methods improve transparency and trustworthiness by revealing which spatial, temporal, or spectral EEG features drive model decisions. The study classifies XAI methods using established taxonomies, identifies research gaps, and calls for more reliable, domain-informed explainability methods.

Unpacking AI's Decision-Making: Post-Hoc vs. Ante-Hoc Interpretability
XAI methods in EEG analysis are primarily categorized by their approach to generating explanations: post-hoc, applied after model training to explain black-box models (e.g., LIME, SHAP, Grad-CAM), or ante-hoc (inherently interpretable), designed for transparency by default (e.g., decision trees, rule lists). The survey reveals a strong reliance on post-hoc methods in current EEG research, highlighting a need for more intrinsically interpretable model designs.

Local vs. Global Explanations: Granularity and Focus
XAI explanations can be local, focusing on individual predictions to identify influential features, or global, aiming to elucidate the model's overall decision logic. The choice depends on the specific task and user needs, with EEG analysis often benefiting from both perspectives to capture both fine-grained and general patterns. Feature attribution and visualization are the dominant explanation types.

XAI in EEG: Transforming Clinical Diagnosis and Research
Explainable AI techniques are being applied across a diverse range of EEG analysis domains, including seizure detection, sleep staging, emotion recognition, and schizophrenia analysis. This broad adoption underscores the potential of XAI to provide crucial insights into brain activity, enhance diagnostic accuracy, and foster clinical trust. However, a significant portion of research remains task-specific, limiting cross-domain generalizability.
Studies focused on Epilepsy/Seizure Detection
Case Study: Interpretable Seizure Detection
A clinical team struggled with the black-box nature of their automated EEG seizure detection system, leading to hesitation in clinical adoption despite high accuracy. They needed to understand why the system made specific predictions to trust its output.
Challenge: Lack of transparency in seizure onset detection, making it difficult for neurologists to validate and trust AI-driven diagnoses. Traditional systems couldn't explain their reasoning, hindering integration into clinical workflows.
Solution: Implemented an XAI framework utilizing SHAP values and Grad-CAM to identify the most influential EEG channels, frequency bands, and temporal segments contributing to seizure predictions. This provided visual and quantitative explanations aligned with neurophysiological knowledge.
Outcome: The neurologists gained trust in the AI system, understanding the specific EEG patterns (e.g., abnormal spike-and-wave discharges in certain brain regions) that led to seizure detection. This led to faster diagnosis, more confident treatment decisions, and improved patient care.
