Comprehensive Source Code Collection for EEG Analysis

The repository offers extensive and diverse source code collections for electroencephalogram (EEG) analysis, covering multiple functional aspects. Power spectral density (PSD) estimation serves as a fundamental analytical method, typically implemented using Welch's method or Fast Fourier Transform (FFT) algorithms to quantify energy distribution across different frequency bands. Event-related synchronization/desynchronization (ERS/ERD) analysis provides crucial research tools for investigating brain synchronization patterns during specific cognitive events, often involving time-frequency analysis and statistical comparison algorithms. Topographic map visualization offers intuitive spatial representation of EEG signals, commonly implemented using interpolation methods and surface plotting functions to display voltage distributions across scalp regions. These code implementations provide comprehensive functionalities and utilities that enable researchers to conduct in-depth investigation and analysis of EEG data through customizable parameter settings and modular programming approaches.
