William McLaughin, Presbyterian, from Alliance, Ohio, spend most of his time (a small part on Meyer Ward) operating the electroencephalograpgh machine. Tiny electrical currents in the brain are amplified by a battery of electrical amplifiers and recorded on a paper tape as wavering lines. With the help of such records, experts (doctors) diagnose abnormalities, such as brain tumors. Bill is shown attaching the "brain-wave machine" electrodes to a patient.
