(A) Example of the location of 256 electrodes on the head determined

Egi 256 Electrodes. A 2D map of the 256 channel 256channel HydroCel Geodesic Sensor Net (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. Quick Application Time Geodesic Sensor Nets use abrasion-free application methods and the Net structure allows all electrodes to be applied at once

(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 The GSN gently holds each silver/silver chloride electrode sensor in place without the need for excessive head measurements or glues.

(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 HD-EEG system (EGI, Electrical Geodesic Inc., 256 electrodes) was used to record brain activity with a sampling rate equal to 1 KHz and electrodes impedances were kept below 50 kΩ. This Technical Note published by EGI describes the average electrode positions for the 128- and 256-channel HydroCel GSN approximate the correspondence between the international 10-10 system elecrode positions with the sensors on the 128- and 256-channel HydroCel GSN.

EEG Laboratory in the Department of Neuroinfomatics. From topleft. Its rapid application and comfortable fit, as well as the rich data it provides, make the GSN ideal for a wide range of subjects/patients and applications. The Geodesic Sensor Net makes high density EEG practical for any lab
