EEG Unit at the Hospital for nervous diseases, Queens Square. A patient lies wired up with leads attached to her head. A sign photographed in another frame reads 'EEG stands for Electroence Phalogram. The EEG is a recording of the very small electrical changes which occur in the brain all the time. These are picked up by a set of 22 damp pads which are placed on the scalp after making small partings in the hair. This is why we ask patients to come for their EEG with clean hair entirely free of grease, cream or lacquer. This is not treatment, it is a test as harmless as x-ray or a photograph. There is no sensation and it has no effect on you during or after the recording. The whole procedure takes about an hour.
