	Electroencephalography - Wikipedia, the free encyclopedia
		EEG can also be used in conjunction with other types of brain imaging.
		Neuroscientists and biological psychiatrists use EEGs to study the function of the brain by recording brainwaves during controlled behavior of human volunteers and animals in lab experiments.
		With halogenated anesthetics and intravenous agents such as propofol, a rapid (alpha or low beta), nonreactive EEG pattern is seen over most of the scalp, especially anteriorly; in some older terminology this was known as a WAR (widespread anterior rapid) pattern, contrasted with a WAIS (widespread slow) pattern associated with high doses of opiates.

	Electroencephalogram (EEG)
		EEG is the most useful and important test in confirming a diagnosis of epilepsy.
		The EEG record is analyzed by a doctor who is specially trained to diagnose and treat disorders affecting the nervous system (neurologist).
		The EEG records abnormalities in the brain waves that may not be confined to one specific area of the brain.

	The Secret Life of the Brain : Scanning the Brain: EEG
		An EEG is a recording of electrical signals from the brain made by hooking up electrodes to the subject's scalp.
		EEGs allow researchers to follow electrical impulses across the surface of the brain and observe changes over split seconds of time.
		An EEG can show what state a person is in -- asleep, awake, anaesthetized -- because the characteristic patterns of current differ for each of these states.

		The EEG trace is usually taken in a hospital or a laboratory setting by men in white coats in front of daunting apparatus.
		A machine which analyses the EEG signal into its separate components easily differentiates between a calm person solving a problem in mental arithmetic and a person who is reacting to the test ambience.
		This is because the muscles are near the surface of the skin and produce large signals whereas the signal which is of interest originates deep in the brain and is severely attenuated in passing through the skull.

	EEG Biofeedback
		EEG Biofeedback is a learning strategy that enables persons to alter their brain waves.
		EEG Biofeedback is used for many conditions and disabilities in which the brain is not working as well as it might.
		If your doctor is familiar with EEG Biofeedback in general, he may still be thinking in terms of the more common early experiments with alpha wave training, rather than with the training we are dealing with here.

	EEG During Carotid Endarterectomy (Site not responding. Last check: 2007-11-07)
		EEG monitoring is frequently employed in many institutions during CEA in either a continuous or intermittent fashion and has been predominantly used to detect cross-clamp related cerebral ischemia.
		Continuous EEG monitoring is preferable since a significant number of strokes do not occur during the period of carotid cross-clamping but after the repair and often result from intraoperative embolization or hyperperfusion.
		EEG monitoring is often employed to determine the need for an intraluminal shunt during the period of carotid cross-clamping.

	EEG Biofeedback Information Summary
		EEG brainwaves in individuals with ADD contain a high ratio of slow waves (theta EEG, 4-8 Hz) to fast activity waves (beta EEG, 16-20 Hz) as compared to persons without ADD.
		Sensors placed on the head record EEG waves, which are represented on the computer screen as a spectrum of frequencies, which are used by the clinician to calibrate the training exercises to follow.
		During training sessions, the subject is presented with a series of tasks (reading, listening to stories, etc.) and is rewarded by changes in the game on the computer screen when he or she produces a certain level of beta wave activity.

		An EEG is recorded by attaching 4 small wires to the head with easily removable disposable tabs to view the brain’s activity on the computer screen.

	EEG BIOFEEDBACK: A CONTROLLED STUDY OF THE EFFECTS OF EEG BIOFEEDBACK ON COGNITION ...
		EEG Biofeedback treatment for Attention Deficit Disorders with or without hyperactivity and Learning Disabilities has emerged as an important component in enhancing attention, cognitive functioning and behavior.
		The EEG Biofeedback consisted of computerized Autogenic A620 and Biocomp instrumentation using a bipolar placement at CZ and Pz The EEG Biofeedback protocol reinforced the enhancement of Beta brain waves (16-20 Hz) and the suppression of Theta brain waves (4-8 Hz) Muscle tension artifact (EKG) was also suppressed as part of this training protocol.
		The significant improvements in intellectual functioning as measured by increases in IQ scores, may be the result of the treatment having an impact on the subjects' ability to attend and concentrate, hence enhancing performance on the subtests which comprise the K-BIT rather than actually increasing their intellectual potential.

	EEG (Electroencephalography)
		The EEG is the key test in diagnosing, pinpointing, and managing certain areas of unstable electrical impulses in the brain that cause epilepsy (in other words, the EEG tries to find the seizure foci).
		EEGs can identify other very rare seizure syndromes, and are also used to judge the effectiveness of anti-convulsion therapy, which is used in the treatment of seizure disorders.
		Although EEGs may record the lack of electrical activity in some comatose patients, which can be used as evidence of brain death, in many other instances EEGs turn up treatable conditions like otherwise undetected seizures disorders or chemical imbalances.

	Introduction to EEG
		The electroencephalogram (EEG) is a recording of the electrical activity of the brain from the scalp.
		The first recordings were made by Hans Berger in 1929 although similar studies had been carried out in animals as early as 1870.
		EEG activity is quite small, measured in microvolts (µV) with the main frequencies of interest up to approximately 30 Hertz (Hz).
