Welcome to the EEG Analysis Platform! 🧠⚡

This repository contains interactive EEG analysis web application, an easy-to-use tool to visualize and analyze EEG signals using complexity and entropy.

The main functionalities of the platform at the moment are:

• Visualization of EEG signals
• Frequency analysis using wavelets
• Entropy analysis.

Features ✨

⚡ EEG Visualization

Load and visualize EEG signals from the Fp1 and Fp2 channels, allowing you to analyze the signals over specific time intervals.

📡 Frequency Analysis

Perform wavelet-based frequency analysis on EEG signals. This feature allows you to explore the frequency spectrum over time and analyze dynamic changes in brainwave frequencies.

📊 Entropy Analysis

Evaluate the complexity of EEG signals by computing entropy measures, such as Shannon Entropy, Approximate Entropy, and Sample Entropy.

EEG Signal Acquisition ⚙️

The EEG data used in this project was acquired with the BITalino NeuroBIT Kit. Electrodes were placed following the international 10-20 system, specifically at Fp1 or Fp2 for brain activity measurement. The reference electrode was placed behind the ear.

Architecture Overview

This platform follows a component-based architecture where each functionality is encapsulated in its own class, ensuring modularity, scalability, and maintainability.

Main Components

• EEGDataLoader: Handles loading EEG data from CSV files.
• EEGVisualizer: Provides functions to visualize EEG data and results.
• EntropyAnalyzer: Calculates various entropy metrics for EEG signals.
• EEGWaveletAnalyzer: Performs continuous wavelet transformation to analyze the frequency content of EEG signals.
• UIElements: Displays reusable UI elements like logos and headings.
