Pure silver-electrodes are polarizable electrodes. They generate slow EEG-frequency under 10Hz a resistance exponentially steeply ascending with the frequency-decrease and take to a distortion of the EEG-signal. Pure silver-electrodes are therefore been not suitable for an EEG recording. They becomes use for EP-recordings however because slow frequencies (undesirable drifts) are not graph.
The shielded/unshielded cable has a length of 120cm and is equipped with a female 2mm or male 2mm pin or dipole plug.
