electroencephalograph

(ĭ-lĕk′trō-ĕn-sĕf′ə-lə-grăf′)
n.
An instrument that measures electrical potentials on the scalp and generates a record of the electrical activity of the brain. Also called encephalograph.

electroencephalograph (EEG)

[ilek′trō·ensef′ələgraf′]
an instrument for receiving and recording the electric potential produced by the brain cells. It consists of a vacuum tube amplifier that magnifies the electrical currents received through electrodes placed on the scalp and electromagnetically records the patterns on a graphic chart. See also electroencephalography.
