Mount and check signals of 16 EEG electrodes in less than 1 minute....

g.tec performed an experiment where 16 active dry EEG electrodes (g.SAHARAelectrode) where mounted. As electrode cap the g.GAMMAcap2 was used. The EEG data was recorded with the new 256 channel biosignal amplifier called g.HIamp.

The combination of these new developments leads to a pathbreaking assembling time for EEG electrodes!

In less than 1 minute, 16 EEG electrodes where mounted and the signal was checked – excellent EEG signals were recorded.

On Youtube you can see…

Up close and personal with a fine wire electrode.

Essentially, the technique employed by neurophysiologists to recorded motor unit activity has remained unchanged since the 1920s.

A fine wire is placed in a hypodermic needle, which is placed inside the skeletal muscle of the volunteer (Fig. 13 from Adrian & Bronk, 1929, J Physiol). The small size of the fine wire offers a small recording volume, which is necessary to isolate the muscle…
