EEG is a procedure that measures the electrical activity of the brain to determine how it responds at different functions.
It involves pacing some electrodes on the scalp, to detect voltage fluctuations within the neurons of the brain. This is displayed in form of graphs or signals which are recorded. A specially trained physician, interprets the readings to make diagnosis of the electrical function of the brain.
EEG is useful in the following conditions
- Epilepsy and seizure disorders
- Sleep disorders
- Depth of anaesthesia
- Stroke and focal brain disorders.
