This repostiory contains the code for the preprocessing and visualiation of EEG siganls with subect data provided for ease of experimenting.
The step by step visualization and preprocessing steps include:
- Loading of subject data
- Removing unnecessary modalities and channels
- Setting up montage
- Artifact removal through ICA with visualization for excluding the ICA components
- High pass filtering for removal of slow drift
- PSD plot for checking powerline noise
- Temporal topomap plots
- Topomap plots for each frequency band (alpha, beta, gamma, theta, delta)
- Difference of topo plots
