This video shows the assembling of 512 EEG channels with the g.Pangolin system, achieving perfect spatial resolution of the visual cortex.

25 years ago, it used to take 60 minutes for 64 channels. With 512 passive EEG electrodes, it would've been an 8-hour ordeal. But with the g.Pangolin system, it's just 30 minutes.

This video serves as a comprehensive preparation guide for VEP experiments conducted by g.tec medical engineering, showcasing the spatial extent and boundaries of different images on the human scalp.
The experiment features the 1024 ultra-high density g.Pangolin system, coupled with g.HIamp and g.HIsys Professional software package.
g.HIamp is a 24-bit biosignal amplifier with 256 ADCs, ensuring perfect synchronization of all EEG channels.

It can be stacked to record from 1024 channels. Each device includes 4 processors for high oversampling and ultra-steep anti-aliasing filtering, enhancing the signal-to-noise ratio. g.HIsys Professional includes a MATLAB/Simulink toolbox and offers hundreds of dedicated signal processing blocks for EEG/EP and ECoG experiments.

New experiments can be defined within minutes, thanks to its speed and efficiency in processing all 1024 channels. The g.Pangolin grid electrodes, with a center-to-center distance of only 8.6 mm and small diameter, allow for recording with exceptionally high spatial resolution.

Standard EEG electrodes, with their larger diameter and gel coverage, limit spatial resolution and proximity. With this setup, we can replicate every EEG experiment with improved resolution.
