HD-EEG GES400

Over 4,500 research papers have been published using EGI’s Geodesic EEG Systems in fields such as developmental neuroscience, cognitive neuroscience, multimodal imaging, clinical research, sleep research, and human performance. A complete list of articles is available here.

EGI’s GES 400 series products include the Net Amps 40 with the   for EEG acquisition, offline review, and analysis.

The system is compatible with most commercial and open-source software packages for stimulus presentation and data analysis.

The Geodesic EEG System uses the comfortable and easy-to-use Hydrocel Geodesic Sensor Net  with 32, 64, 128, or 256 sensors.

• Using 32 to 256 electrodes evenly spaced over the entire scalp, cheeks, and back of the neck, Geodesic EEG provides dense and even sampling, allowing you to detect brain activity at high spatial resolution, without having to interpolate between widely spaced sensors.
• The Net Amps 400 amplifiers are designed specifically for EGI’s Geodesic Sensor Net and provide low noise and high sensitivity required for acquiring high-quality EEG data.
• The HCGSN gently holds each silver chloride plated 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 gel for long-term recording.
• The sensor net is a comfortable and low stress experience for your participants — even infants, children, or populations with behavioral challenges easily accept the HCGSN.

EGI’s Net Station 5 suite of software provides full acquisition, review, and processing functions in a complete package, with an intuitive interface and faster processing times.

Net Station software saves data files in Metafile Format (MFF) which can be directly imported into Matlab or Python applications and toolboxes using the free MFFMatlabIO plugin or exported to the EDF+ format, MAT files, or your own custom software.
