EEG
Neural activity monitor
EEG stands for electroencephalogram—a recording of electrical activity in the brain, made by placing electrodes on the scalp.
Doctors use EEGs to diagnose epilepsy, sleep disorders, and brain injuries.
The word also refers to the test itself: The neurologist ordered an EEG.
As a verb, rare: They EEG'd the patient overnight.
