Yeah, M's video EEG was hooked up to a recorder and monitored on a video-tube monitor. Equipment meant to sense micro/nano-volts of brain wave activity would certainly be susceptible to the EMI from a video tube.

Named after the German mathematician Carl Friedrich Gauß (Gauss), the Gauss is a unit of magnetic flux. The term degauss came to mean a method applied to removing magnetic flux inherited in a material. The old TV repairman used to use a "degaussing" coil to remove inherited flux from the video mask of old TV picture tubes. Later designs employed a loop around the tube itself which would carry a diminishing (a 1/RLC time circuit) alternating current to degauss the tube's mask when the set was turned on.
FWIW, this too transmits a significant bit of EMI.

It's not yet found in the Oxford Concise OED but it's become a common lexicon that has been incorporated in the more common dictionaries.
