The BEL EEG System One is the foundation of the Geodesic EEG Ecosystem – an environment built for human neurophysiology research. It includes: the Geodesic Head Web for dense array electrode acquisition, the miniaturized and portable BEL Amp One, the BEL View software for elegant data visualization and the open-source software FLOW, for data review and analysis, with integral file storage and management.
