Overview

This project implements a MATLAB-based EEG spectral analysis pipeline for computing:

• Posterior alpha power (8–12 Hz)
• Frontal theta power (4–8 Hz)
• Theta/Alpha ratio biomarker

Dataset

MIPDB preprocessed EEG dataset.

Methods

• FFT-based power spectral density (no Signal Processing Toolbox required)
• Automatic frontal/posterior channel detection
• Regional band power averaging

Outputs

• Alpha power per channel
• Theta power per channel
• Posterior alpha (regional)
• Frontal theta (regional)
• Theta/Alpha ratio

Example Output

Theta/Alpha ratio ≈ 3.63 (example subject)
