(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.

Although most of the studies screened their participants for such conditions as dementia, Parkinson's disease, Alzheimer's disease, and other diseases that cause brain damage that could cause visual hallucinations, only a small number used fMRI's, positron emission tomography scans, electroencephalographs, and computed axial tomography scans in their studies to confirm the absence of these potential causes (Berrios & Brook, 1984; ffytche et al.
