Electrodes for use in electroencephalographic recording including consciousness and seizure monitoring applications have novel features that speed facilitate or enforce proper placement of the electrodes including aligning tabs and arrowed aligning juts color coding and an insulating bridge between reference and ground electrodes which ensures a safe application distance between the conductive regions of the two electrodes in the event of cardiac defibrillation. A method of using a set of four such electrodes is also disclosed.
