About Electroencephalogram (EEG):
- It is a recording of brain activity. It is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain.
- Procedure:
- During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.
- The charges are amplified and appear as a graph on a computer screen or as a recording that may be printed out on paper.
- Applications:
- The EEG is used to evaluate several types of brain disorders.
- The EEG may also be used to determine the overall electrical activity of the brain (for example, to evaluate trauma, drug intoxication or extent of brain damage in comatose patients).
- The EEG may also be used to monitor blood flow in the brain during surgical procedures.
