MAGSTIM EGI

 

A complete High Density EEG system that provides the ultimate in spatial resolution for any research application. The Geodesic EEG System (GES) 400 features on-board processing, state-of-the-art electronics, and remote upgrade capability. The GES 400 is also easily upgradable for multimodal imaging with integrated tES, fMRI, and more.

Geodesic Transcranial Electrical Neuromodulation 200 (GTEN 200)*

 

Record HD EEG and deliver current simultaneously using the same Geodesic Sensor Net

​

A single integrated platform featuring:

​

  • Options for 32, 64, 128, or 256 channel sensor nets allowing any electrode to serve as anodes, cathodes or recording electrodes

  • Up to 2 mA current intensity for custom HD tDCS, tACS, tPCS, and tRNS protocols

  • Individualized head modeling and a library of age-matched atlases

  • Source localization tools (LORETA, sLORETA, LAURA)

  • Software Developer’s Kit (SDK) included complimentary

GTEN 2OO Neuromodulation Research System

​

Robust planning tools to optimize for each individual

​

Create an MR-based individualized head model or select an age-matched atlas

  • Account for intersubject differences from the start

Design your custom stimulation protocols in one of three ways:

  • Manually select electrodes and current level

  • Choose a region of interest within the brain to target

  • Use EEG-based source localization to guide the stimulation paradigm

Localize with confidence

  • High density, whole head electrode coverage and finite difference method head models allow for highly accurate source localization

Apply the reciprocity theorem to align stimulation with physiology

  • A cortical source’s scalp voltage projection is the same as the scalp stimulation required to stimulate/modulate that cortical source 1

 

Maximize flexibility with a larger array of montages

​

Localize targeting by selecting, combining custom stimulation arrays

  • Up to 256 channels of EEG, of which 190 channels can be used for stimulation, with spatial selectivity to stimulate multiple anodal/cathodal pairs at a given time (minimum of 10 pairs needed to achieve maximum current)

Achieve greater focality with smaller stimulation sensors

  • 1cm2 enables 0.2mA/cm2 current density in patch electrodes

Measure the targets and effects with HD EEG

  • Use EEG-based source localization to guide the stimulation paradigm and seamlessly record EEG while stimulating

Close the loop and change protocols in real-time driven by physiology

  • Use the Software Developers’ Kit (SDK) and other open-source platforms to develop and perform closed-loop neuromodulation
