EEG Systems


Geodesic EEG Systems  NEW! Now with EEGLAB plug-in
A complete High Density EEG system that provides the ultimate in spatial resolution for any research application. GES 400, 405, and 410 feature on-board processing, state-of-the-art electronics, and remote upgrade capability. GES 400 and 410 are also easily upgradable for multimodal imaging with fMRI and MEG.


fMRI/MEG-compatible Geodesic EEG Systems
EGI's MR-compatible EEG Systems can be used for simultaneous EEG-fMRI and simultaneous EEG-MEG.


Electrical Source Imaging

geosource3largeiconNEW! GeoSource 3 electrical source imaging packages
A powerful platform for electrical source imaging, with individual FDM head models, improved atlas head models, and support for advanced neuromodulation planning and other advanced research applications. For Research Use Only.



GPS Photogrammetry-based sensor digitization
Innovative technology for sensor localization; used with GeoSource software to improve source estimation.


EGI's interoperability program includes compabilities with BESA, BrainVoyager, Curry, MATLAB Toolbox, Presentation, and Cartool.

GeoScan Icon68

GeoScan handheld sensor digitization
Stereo camera tracking technology measures, identifies, and creates a 3D coordinate file of EEG sensor locations in real time. For use with electrical source imaging software, such as GeoSource 3.0 Research software. For Research Use Only.

BESA and BrainVoyager
In addition to EGI's own GeoSource source imaging software, we also distribute third-party source imaging software, BESA and BrainVoyager.


Neuromodulation/EEG Systems


Precise, non-invasive neuromodulation with simultaneous EEG and the flexibility to choose from 256 electrodes for tDCS, tACS, or tPCS neuromodulation. Advanced planning and targeting software uses individual, atlas, or conformal/warped atlas Finite Difference Method (FDM) head models. For Research Use Only.
