An electroencephalogram (EEG), also called a brain wave test, is a diagnostic test which measures the electrical activity of the brain (brain waves) using highly sensitive recording equipment attached to the scalp by fine electrodes.
Electroencephalogram (EEG): Electrodes (small, sticky metal patches attached to the scalp) are connected by wires (leads) to an electroencephalograph machine to chart the brain's continuous electrical activity.
Some electrophysiological tests are the auditory brainstem response (ABR) test, auditory steady-state response (ASSR) testing, electroencephalic audiometry (EEG) test, and otoacoustic emission testing (OAE).
By measuring brainwave activity and teaching the AD/HD patient which type of brainwave is associated with attention, EEG biofeedback attempts to train patients to generate the desired brainwave activity.
Because of the benign nature of the simple febrile seizure, tests such as computed tomography (CT) scans, magnetic resonance imaging (MRI), or electroencephalogram (EEG) are not usually recommended.
In the case of mild head injury or postconcussion syndrome, CT and MRI scans, electroencephalograms (EEG), and routine neurological evaluations all may be normal because the damage is so subtle.
Using EEG technology, the same technology that reads your brain waves for diagnostic purposes, the Mindflex game is able to read your brainwaves and use them to control a fan inside a console.
NeuroSky, a 12-employee company in California founded in 1999, is using EEG waves (electroencephalography) to measure the brain's electrical activity through electrodes placed on the scalp.
The healthcare provider could also be asked to limit the number of strangers entering and leaving the room during the EEG procedure, since they can raise the patient's anxiety level.
The patient may also be asked to do certain things during the EEG recording, such as breathing deeply and rapidly for several minutes or looking at a bright flickering light.
