An electroencephalogram (EEG) is a neurophysiologic technique primarily used in the evaluation of epilepsy (or possible epilepsy), but it may also be recommended for headaches, behavioral …

Nov 9, 2021 · An electroencephalogram (EEG) is a test used to evaluate the electrical activity in your brain. It can help detect potential problems with brain cell communication.

Dec 18, 2023 · 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.

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 …
