A professional who measures electrical activity of brain waves, using electroencephalograph (EEG) instrument, and conducts evoked potential response tests for use in diagnosis of brain and nervous system disorders. Responsibilities include:

• Measures patient's head and other body parts, using tape measure, and marks points where electrodes are to be placed.
• Attaches electrodes to predetermined locations, and verifies functioning of electrodes and recording instrument.
• Operates recording instruments (EEG and evoked potentials) and supplemental equipment and chooses settings for optimal viewing of nervous system.
• Records montage (electrode combination) and instrument settings, and observes and notes patient's behavior during test.
• Conducts visual, auditory, and somatosensory evoked potential response tests to measure latency of response to stimuli.
• Writes technical reports summarizing test results to assist physician in diagnosis of brain disorders.
• May perform other physiological tests, such as electrocardiogram, electrooculogram, and ambulatory electroencephalogram.
• May perform video monitoring of patient's actions during test.
• May monitor patient during surgery, using EEG or evoked potential instrument.
• May supervise other technologists and be known as Chief Electroencephalographic Technologist.
