Electrode An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from the Greek words elektron, meaning amber (from which the word electricity is derived), and hodos, a way.

- Electroencephalogram (EEG) Guide. An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Special sensors (electrodes ) are attached to your head and hooked by wires to a computer. The computer records your brain's electrical activity on the screen or on paper as wavy lines.

What is a cathode, anode, and electrode? An electrode is a conductor of electricity used to make contact with a nonmetallic part of a circuit. Anodes and cathodes are both electrodes in an electro-chemical cell (e.g. battery). The anode is the positively charged electrode and the cathode is the negatively charge electrode.

Atrial Fibrillation What Is an Electrocardiogram? An electrocardiogram (e-lek-tro-KAR-de-o-gram), also called an EKG or ECG, is a simple, painless test that records the heart's electrical activity. To understand this test, it helps to understand how the heart works. With each heartbeat, an electrical signal spreads from the top of the heart to the bottom. As it travels, the signal causes the heart to contract and pump blood. The process repeats with each new heartbeat.

- 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.

CHEMISTRY GLOSSARY electrode potential. elektrodni potencijal. Electrode potential is defined as the potential of a cell consisting of the electrode in question acting as a cathode and the standard hydrogen electrode acting as an anode. Reduction always takes place at the cathode, and oxidation at the anode.

What is an Electrode? Anodes and Cathodes. In the case of a direct (DC) current, electrodes come in pairs, and are known as anodes and cathodes. For a battery, or other DC source, the cathode is defined as the electrode from which the current leaves, and the anode as the point where it returns.

Electrocardiogram (ECG or EKG) What is an electrocardiogram (ECG, EKG)? The electrocardiogram (ECG or EKG) is a noninvasive test that is used to reflect underlying heart conditions by measuring the electrical activity of the heart. By positioning leads (electrical sensing devices) on the body in standardized locations, information about many heart conditions can be learned by looking for characteristic patterns on the EKG.

Electrodermal activity Electrodermal activity (EDA), is the property of the human body that causes continuous variation in the electrical characteristics of the skin.weating is controlled by the sympathetic nervous system, and skin conductance is an indication of psychological or physiological arousal. If the sympathetic branch of the autonomic nervous system is highly aroused, then sweat gland activity also increases, which in turn increases skin conductance.

- An EEG, or electroencephalograph, is a test to measure brain activity. During an EEG, numerous electrodes in the form of patches are applied to the head. These electrodes detect the electrical activity in the brain, and a graph of that activity is generated.

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. The charges are amplified and appear as a graph on a computer screen, or as a recording that may be printed out on paper. Your healthcare provider then interprets the reading.

Overview The electroencephalogram (EEG) is the depiction of the electrical activity occurring at the surface of the brain. This activity appears on the screen of the EEG machine as waveforms of varying frequency and amplitude measured in voltage (specifically microvoltages). EEG waveforms are generally classified according to their frequency, amplitude, and shape, as well as the sites on the scalp at which they are recorded. The most familiar classification uses EEG waveform frequency (eg, alpha, beta, theta, and delta).

- A positive electrode is an “anode,” a terminal through which the negative charge leaves a cell as the current flows into the cell from the outside. Conversely, a negative electrode is a “cathode,” a terminal through which the negative charge enters a cell as the current flows out. Continue Reading.

Electrocardiogram (ECG, EKG) What Is an Electrocardiogram (ECG, EKG)? The electrocardiogram (ECG or EKG) is a diagnostic tool that is routinely used to assess the electrical and muscular functions of the heart. While it is a relatively simple test to perform, the interpretation of the ECG tracing requires significant amounts of training. Numerous textbooks are devoted to the subject. The heart is a two stage electrical pump and the heart's electrical activity can be measured by electrodes placed on the skin.
