EEG (Electroencephalogram) An electroencephalogram (EEG) is a test used to evaluate the electrical activity in the brain. Brain cells communicate with each other through electrical impulses. An EEG can be used to help detect potential problems associated with this activity. The test tracks and records brain wave patterns.

What are Muscle disorders? Definition. 1  Electromyography (EMG) is an electrical recording of muscle activity that aids in the diagnosis of neuromuscular disease. 2  Muscles are stimulated by signals from nerve cells called motor neurons. This stimulation causes electrical activity in the muscle, which in turn causes contraction. This electrical activity is detected by a needle electrode inserted into the muscle and connected to a recording device. Together, the electrode and recorder are called an electromyography machine.

The Electroretinogram and Electro-oculogram: Clinical Applications by Donnell J. Creel The global or full-field electroretinogram (ERG) is a mass electrical response of the retina to photic stimulation. The ERG is a test used worldwide to assess the status of the retina in eye diseases in human patients and in laboratory animals used as models of retinal disease.

Top 20 coach-QB duos: Urban Meyer, Cardale Jones are easy No. 1 1. Ohio State: Urban Meyer-Cardale Jones. Meyer might be the top coach in the land right now and no quarterback is hotter than Jones -- be it on social media, on the field or in the 2016 NFL Draft prospect rankings. The defending national champs are a default No. 1 until someone knocks them off.

- In electroencephalography, small metal sensors (electrodes) are applied to your scalp to record the electrical signals produced by nerve cells in the brain. The electrodes transmit this information to a machine that magnifies the electrical activity and provides a graphic representation of brain waves.

Electroencephalography For other uses, see EEG (disambiguation). Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used in specific applications.

Electroencephalogram (EEG) An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.

electromyogram electromyogram (EMG). Recording of electrical activity of a muscle associated with contraction and relaxation. This is obtained by placing a microelectrode within a muscle.The recording process is called electro-myography. diagnostic test that records the electrical activity of muscles. In the test, small electrodes are placed on or in the skin; the patterns of electrical activity are projected on a screen or over a loudspeaker. This procedure is used to test for muscle disorders, including muscular dystrophy. Mentioned in: Myopathies.

Overview Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract.An EMG translates these signals into graphs, sounds or numerical values that a specialist interprets. nerve conduction study, another part of an EMG, uses electrodes taped to the skin (surface electrodes) to measure the speed and strength of signals traveling between two or more points. EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission. 1  Why it's done.
