EEG lets you eavesdrop on your brain's electrical conversations. Learn how electroencephalography works, what brainwaves reveal, and why it matters.

4 days ago · An EEG (Electroencephalogram) is a non-invasive medical test that records the electrical activity of the brain. The brain is made up of billions of neurons that communicate with each other …

An electroencephalogram (EEG) is a test to measure the electrical activity of the brain.

The EEG is examined for asymmetries between the 2 hemispheres (suggesting a structural disorder), for excessive slowing (appearance of 1- to 4-Hz, 50- to 350-muV delta waves, as occurs in …
