An EEG (electroencephalogram) is a test that evaluates brain function. Healthcare providers order an EEG to diagnose brain issues like epilepsy. 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.

Understanding the Context

Your brain cells... An electroencephalogram (EEG) detects abnormal brain waves that cause seizures. EEG uses include diagnosing epilepsy, sleep disorders, and brain tumors. An electroencephalogram (EEG) is a test that records the electrical activity of your brain using small sensors placed on your scalp.

Key Insights

An electroencephalogram (EEG) is a recording of the brain's electrical activity. Metal electrodes attached to the skin on the outside of the head transform electrical activity into patterns, commonly called brain waves. 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. An electroencephalogram (EEG) is a test used to evaluate the electrical activity in your brain.

Final Thoughts

It can help detect potential problems with brain cell communication.
