Electroencephalography (EEG) The electroencephalogram (EEG) is a measure of brain waves. It is a readily available test that provides evidence of how the brain functions over time. 1  The EEG is used in the evaluation of brain disorders. 2  Most commonly it is used to show the type and location of the activity in the brain during a seizure.

EEG test EEG is a safe test with no side effects. However, a person with epilepsy may experience a seizure, triggered by the various stimuli used in the procedure, including the flashing lights. (This is not seen as a 'complication' by medical staff, because a seizure during an EEG can greatly help in diagnosis.)

Heart Disease, Electrocardiogram, and Specialized EKGs An electrocardiogram (also called EKG or ECG) is a test that records the electrical activity of your heart through small electrode patches attached to the skin of your chest, arms, and legs. An EKG may be part of a routine physical exam or it may be used as a test for heart disease.

EEG (Electroencephalogram) What It Is. 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.

Electroencephalography Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain.It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used in specific applications.EG measures the brain's electrical activity directly, while other methods record changes in blood flow (e.g., SPECT, fMRI) or metabolic activity (e.g., PET, NIRS), which are indirect markers of brain electrical activity.

Routine EEG The EEG recording shows rhythmical electrical activity, often called brain waves. The brain waves may be normal or show abnormalities in certain regions. In people with epilepsy, there may be epileptic activity on the EEG indicating their predisposition to seizures. This epileptic activity can take several forms and be either generalised (recorded over all regions) or focal (recorded in one or more localised regions).
