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.

Geodesic Sensor Nets are available as components of EGI's Geodesic EEG System (GES) products. The Geodesic Sensor Net (GSN) has been widely adopted by the neuroscience research community because of its ease of use, comfort, and ability to produce high-quality and high-resolution data.

When visualizing your dense array EEG data in third-party software, it is sometimes necessary to incorporate the 3D sensor position information of the HydroCel Geodesic Sensor Net (HC GSN) into the destination software.

The current study compares techniques for averaging electrode locations from 86 participants with the 128 channel “Geodesic Sensor Net” (GSN; EGI, Inc.), 38 participants with the 128 channel “Hydrocel Geodesic Sensor Net” (HGSN; EGI, Inc.), and 174 participants with the 81 channels in the 10-10 configurations.

EGI currently offers two versions of the Geodesic Sensor Net: the HydroCel GSN (HCGSN) and GSN 200. This manual discusses the two models together because they share many similarities. General information about their individual properties is provided in Chapter 2, "HCGSN,”...

2018年7月5日 · Geodesic Sensor Net (GSN) from Electrical Geodesics, Inc. (EGI) is the first practical, safe method for quickly placing 32 to 256 electrodes on the human head to acquire dense-array electroencephalography (EEG) data.

Whenever I load the EGI file, it shows the following in the MATLAB window and identifies GSN-128 channel as a default channel location.

We studied the impact of 2D and 3D educational contents on learning and memory recall using electroencephalography (EEG) brain signals.

2017年2月14日 · I have a question about the sensor layout map for EGI hydrocel sensor nets. I have been studying the two figures attached - one is the 128 channel map provided by EGI, the other is the sensor positions determined by using the commands mne.channels.read_montage('GSN-HydroCel-128') and mne.viz.plot_sensors.
