What is the definition or description of: eeg?

EEG: Electroencephalography is recording of electrical activity along the scalp. It measures voltage fluctuations resulting from ionic current flows within the brain neurons (nerve cells). Some uses are for diagnosis of epilepsy, exploring causes of delirium, confirming brain death, and to determine whether to wean off of seizure medications.

Electroencephalogram: An electroencephaolgram (eeg) is a test that uses wires on the scalp to measure electrical activity produced by the brain. It is used to assess cerebral activity, and can be very helpful in the diagnosis and treatment of seizures as well as other brain disorders.
