Electroencephalogram

[Julian]

An [electroencephalogram] ([EEG]) is a test used to find problems related to electrical activity of the brain.

An EEG tracks and records [brain wave] patterns. Small metal discs with thin wires (electrodes) are placed on the scalp, and then send signals to a computer to record the results. Normal electrical activity in the brain makes a recognizable pattern. Through an EEG, doctors can look for abnormal patterns that indicate seizures and other problems.
