An interactive, modular course for learning how to read electroencephalograms (EEG).

The recording of these signals is referred to as electrocorticography (ECoG), subdural EEG (SDE), intracranial EEG (iEEG), or stereotactic EEG (SEEG). The signal recorded from ECoG is on a …

Dec 8, 2025 · An electroencephalogram (EEG) detects abnormal brain waves that cause seizures. EEG uses include diagnosing epilepsy, sleep disorders, and brain tumors.

Nov 9, 2021 · 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.

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.

Jan 13, 2025 · 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 …

Dec 9, 2024 · Electroencephalography (EEG) is a non-invasive diagnostic test that records the brain’s electrical activity. By detecting abnormalities in brain waves, EEG provides valuable insights into …
