1) The Geodesic Electroencephalography (EEG) system is a EEG sensor application method. The EGI's advanced EEG technology for neuroscience research uses the comfortable and easy-to-use Geodesic Sensor Net (GSN) with 256 sensors. The GSN holds each electrode sensor in place without the need for excessive head measurements or glues. And no scalp abrasion is necessary to get high-quality EEG data. Use with a simple saline solution for shorter recordings, or an inexpensive paste or gel for long-term recording. 2) Net Station EEG Software is an extensible software platform for fully networked and integrated EEG, electrical source imaging, and neuromodulation. 3) Geosource is a platform for electrical source imaging.
