‘Phantom head’ may one day take guesswork out of EEG monitoring

ABERDEEN PROVING GROUND, Md. (Dec. 24, 2015) — Electroencephalography, or EEG, has been used for decades to measure voltage fluctuations in different parts of the brain to graph a person’s neural patterns.

IMPORTANCE OF EEG

EEG patterns, or waves, provide insights into what the person is seeing, hearing, thinking and feeling, sort of peering into individual’s mental and emotional state.

Medical facilities use EEGs extensively to test for such things as psychological disorders, brain injuries and monitoring the effects of sedatives and anesthesia.

The U.S. Army Research Laboratory, or ARL, also uses EEGs to help design equipment for Soldiers to help them with complex cognitive tasks, said David Hairston, an ARL neuroscientist here. Continue reading
