EEG Analysis Evolution & AI Convergence
EEG has evolved from a subjective method into a data-intensive field using sophisticated algorithms. This review covers neurophysiological foundations, recording techniques, and traditional analytical methods.
The field is rapidly shifting towards 'Large EEG Models' and Generative AI, including Foundation Models like LLMs and LVMs, adapted for high-dimensional neural sequences. Explainable AI (XAI) is crucial for clinical interpretability.
The future of EEG analysis will likely involve Neuro-Symbolic architectures, combining generative AI with classical signal theory for interpretable neural decoding.

Hodgkin-Huxley Model: Predicting Action Potentials
The Hodgkin-Huxley model accurately describes the generation and propagation of action potentials by modeling changes in neuronal membrane permeability to Na+ and K+ ions. This foundational work laid the groundwork for modern computational neuroscience.
Impact: It provided a predictive theory, not just a description, enabling the simulation of complex neuronal dynamics and understanding their electrical basis. Its principles inform modern neural signal generation models.
EEG has transformed into a data-intensive field, leveraging advanced signal processing techniques for reliable quantitative information extraction.

Fractal Dimension as a Biomarker
Fractal Dimension (FD) measures the complexity/roughness of EEG signals, tracing brain maturation (increased complexity from childhood to adolescence) and detecting neurological disorders (Alzheimer's, Parkinson's, epilepsy) often before spectral changes.
Impact: FD provides a sensitive, noise-robust biomarker for physiological changes and pathological states. Hybrid models feeding fractal features into DL architectures improve pre-ictal state detection.
The integration of AI, from traditional ML to cutting-edge Foundation Models, is revolutionizing EEG analysis, enabling unprecedented insights and applications.
