Geodesic EEG System 400 series for research
EGI's advanced EEG technology for neuroscience research uses the comfortable and easy-to-use Geodesic Sensor Net with 32, 64, 128, or 256 sensors and Interoperates with most presentation and analysis software.
EGI’s Geodesic EEG System 400 (GES 400) series products introduce the Net Amps 400 series of amplifiers with EGI's ADAPT technology and completely redesigned Net Station 5 suite of software for EEG acquisition, review, and analysis.
Engineered with a vision for the future, the GES 400 series products provide a strong foundation for the growing neuroscience laboratory.
GES 400 — the GES 400 introduces EGI’s ADAPT amplifer technology, which builds on-board computing directly into the amplifier and introduces several hardware and firmware upgrades. Read about the Net Amps 400 series of amplifiers.
GES 405 — the most affordable product for Geodesic EEG, this system is designed for 32-channel EEG only
The GES product line offers you:
- Whole head coverage — evenly spaced sensors provide full scalp coverage for the highest spatial resolution data — choose from 32, 64, 128, or 256 channels
- Expandability — GES products are designed to grow with your lab — you can start small and add increased channel counts or additional functionalities as your needs change
- Multimodal imaging capability — with upgrade modules, GES 400 products can be used in MR or MEG environments, and all GES products are compatible with EEG-TMS
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 foundation platform for your EEG laboratory
The GES products are complete systems with EEG sensors, amplifier, and software:
Geodesic Sensor Net (GSN)
EGI’s proprietary Geodesic Sensor Net provides a simple method to apply dense arrays of sensors quickly and easily — you can apply up to 256 sensors in just a few minutes.
The GSN gently holds each silver/silver chloride 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.
The result is a comfortable and low stress experience for your participants — even infants, children, or populations with behavioral challenges easily accept the GSN.
Net Amps 400 amplifiers
The Net Amps 400 ampifiers are designed specifically for EGI’s GSN and provide the low noise and high sensitivity required for acquiring high-quality EEG data. The Net Amps 400 smart amplifier provides hardware with a built-in Intel chip that allows remote updates. More.
Net Station software
EGI’s Net Station 5 suite of software provides full acquisition, review, and analysis functions in a complete package, with an intuitive interface and faster processing times. More.
Net Station software saves data files in Metafile Format (MFF), which can be exported to the EDF+ format, MATLAB, EEGLAB, FieldTrip, or your own custom software. More.
Building on the GES foundation
The GES products integrate with EGI and third party hardware and software, allowing you to expand your system to include:
Through the Interoperability Standards Program, EGI works directly with other companies and software developers to develop practical hardware connections and seamless movement of data between programs. Amp Server Pro SDK is available for developers to establish direct connection to the amplifer with custom software.
ApplicationsOver 1,500 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.
