An EEG (electroencephalogram) measures muscular activity and messages sent from the core muscles to the brain

On an EEG, wave patterns vary among individuals in response to anesthetics, drugs, and pathologic and physiologic changes. The EEG can reveal the presence of organic brain damage, abnormal physiologic alterations, and actions of drugs. Electrodes placed on the scalp transmit the electrical signals, alpha rhythms, from brain activity. This electrophysiologic monitoring provides information about the functional integrity of the central nervous system during anesthesia and is especially valuable in patients undergoing high-risk neurosurgical, cardiac, vascular, or orthopedic procedures.
