Covariance matrices of EEG signals and estimated cortical sources from 15 subjects presented with visual stimuli

Covariance matrices of EEG signals and estimated cortical sources from 15 subjects presented with visual stimuli of 3D-Tunnels and Checkerboards. This dataset is the basis of an article named "Riemannian classification of single-trial surface EEG and sources during checkerboard and navigational images in humans".
