EEG (electroencephalogram) - Mayo Clinic
2024年5月29日 · 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.
Electroencephalogram - StatPearls - NCBI Bookshelf
2022年10月3日 · An electroencephalogram (EEG) is an essential tool that studies the brain's electrical activity. Despite developing more advanced imaging techniques, EEG remains the essential paraclinical tool for seizure evaluation. It is primarily used to assess seizures and conditions that may mimic seizures.
EEG (Electroencephalogram): What It Is, Procedure & Results
2024年3月8日 · An electroencephalogram (EEG) tests your brain function. Healthcare providers order EEGs to diagnose conditions that affect your brain. Providers may use the term EEG for the test itself and what it shows.
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.
Introduction - Electroencephalography (EEG): An Introductory Text …
The EEG is an electrophysiological technique for the recording of electrical activity arising from the human brain. Given its exquisite temporal sensitivity, the main utility of EEG is in the evaluation of dynamic cerebral functioning.
EEG Normal Waveforms - StatPearls - NCBI Bookshelf
2023年7月24日 · The normal EEG is extremely diverse and has a broad range of physiological variability. This activity illustrates EEG normal waveforms, and explains the role of the interprofessional team in improving care of patients who are evaluated by EEG. Objectives: Explain the temporal summation of the cortical neurons in an EEG.
