  scope: This Recommendation concerns analogue electroencephalographs, which are defined
    as diagnostic medical instruments having at least eight channels. Such instruments
    are intended to accurately measure and record bioelectrical potentials and their
    time sequences as detected by electrodes attached to the surface of the human
    scalp.
