electrode

 [e-lek´trōd]
either of two terminals of an electrically conducting system or cell; specifically, the uninsulated portion of a lead that is in direct contact with the body.
active electrode therapeutic electrode.
calomel electrode one capable of both collecting and giving up chloride ions in neutral or acidic aqueous media, consisting of mercury in contact with mercurous chloride; used as a reference electrode in pH measurements.
depolarizing electrode an electrode that has a resistance greater than that of the portion of the body enclosed in the circuit.
hydrogen electrode an electrode made by depositing platinum black on platinum and then allowing it to absorb hydrogen gas to saturation; used in determination of hydrogen ion concentration.
indifferent electrode one larger than a therapeutic electrode, dispersing electrical stimulation over a larger area.
point electrode an electrode having on one end a metallic point; used in applying current.
therapeutic electrode one smaller than an indifferent electrode, producing electrical stimulation in a concentrated area; called also active electrode.

e·lec·trode

(ē-lek'trōd),
1. Device to record one of the two extremities of an electric circuit; one of the two poles of an electric battery or of the end of the conductors connected thereto.
2. An electrical terminal specialized for a particular electrochemical reaction.

electrode

Cardiac pacing A part of an electric conductor through which a current enters or leaves; uninsulated conductive part of a pacing lead or a unipolar implantable pulse generator's casing which makes electrical contact with tissue; electrodes are used to record the electric activity of contracting muscles; electromyographic data is collected by surface electrodes, fine wire and needle electrodes. See Ring electrode, SilverBullet electrode, Tip electrode.

Note that the variability in the control signal among the different experiments reflects differences in the precise placements of the carbon fiber and stimulating electrodes, as well as the brain area in which dopamine was recorded.
Stimulation of the spinal cord with either a single concentric bipolar electrode or two monopolar electrodes placed at locations several centimeters distant from each other along the longitudinal axis of the cord was only occasionally successful in eliciting repeatable EODs, despite numerous repositionings of the stimulating electrode or electrode pairs.
(9) The stimulating electrodes are commonly placed over the median nerve and ulnar nerve for the upper limbs and the posterior tibial nerve and the peroneal nerve for the lower limbs (Fig.
Tests with and without stimulating electrodes showed that no interference of the affixed cathodal electrode occurred.
Triolo and his colleagues at the Louis Stokes Cleveland VA Medical Center and Case Western University to optimize the design of stimulating electrodes to selectively activate the nerves that control the muscles for standing, balance, and stepping.
In the 1950s, a few seriously depressed patients had stimulating electrodes implanted in their brain's pleasure centers.
During the study, adult animals were implanted with brain stimulating electrodes. Measures of their wheel spinning effort were made before, during and after they received various doses of either mephedrone or cocaine.
In clinical trials, some patients now are able to independently control the place and time of urination by stimulating electrodes implanted at the appropriate nerve roots.
In conclusion, the in vitro preparation of frog nose and brain is a system which, by offering access for stimulating electrodes to the forebrain nuclei from which these fibers arise, permits us to study the effects of centrifugal ACh release in the OB.
During both median and ulnar sensory conduction recordings, ground electrode was placed between recording and stimulating electrodes. Care was taken to keep same distance between stimulating and recording electrode for both median and ulnar nerves at wrist.
