Abstract:
:This paper discusses the 50-Hz artifact observed during EEG recording of three patients, using Mindset24 equipment in a biomedical laboratory along with other instruments. The artifact at 50 Hz is created due to electromagnetic (EM) radiation from the environment. Perhaps, the nullification of 50 Hz artifact occurs by the three important means such as (a) grounding of far-field EM current when the patient touches the equipment metal casing, (b) connecting the electrodes in a sequence to obtain differential potentials with suppressed near-field EM radiation potentials of the scalp, and (c) destructive interferences of the EM waves.
