- EEG (electroencephalogram) - Mayo Clinic
An electroencephalogram (EEG) is a test that measures electrical activity in the brain This test also is called an EEG The test uses small, metal discs called electrodes that attach to the scalp Brain cells communicate via electrical impulses, and this activity shows up as wavy lines on an EEG recording
- EEG (Electroencephalogram): What It Is, Procedure Results
An EEG works by measuring the electrical signals or impulses that travel between your brain cells EEGs track those signals by using electrodes that attach to wires that sense electrical impulses
- Electroencephalogram (EEG) - Johns Hopkins Medicine
An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain During an EEG, electrodes are pasted onto your scalp These are small metal disks with thin wires They detect tiny electrical charges that result from the activity of your brain cells
- EEG (Electroencephalogram): Uses, Procedure, Risks
An EEG is a test that records the electrical activity in your brain It is most often used to diagnose epilepsy, but it can also be used for head injuries, brain tumors, stroke, and infections such as encephalitis
- EEG (Electroencephalogram): Purpose, Procedure, and Risks
An EEG is a test that measures your brain waves and helps detect abnormal brain activity The results of an EEG can be used to rule out or confirm medical conditions

An EEG, or electroencephalogram, is a test that records the electrical signals of the brain by using small metal discs (called electrodes) that are attached to your scalp
- 10 conditions that an EEG diagnoses - Medical News Today
An EEG records the brain's electrical activity Doctors use it to detect and diagnose neurological conditions, sleep disorders and brain trauma
- EEG Procedure - Simply Psychology
An EEG (electroencephalogram) records your brain’s electrical activity using painless electrodes placed on the scalp It measures brainwaves like delta, theta, alpha, beta, and gamma, helping to assess brain states such as sleep, alertness, and relaxation
