| voltage clamp | <physiology, technique> A technique in electrophysiology, in which a microelectrode is inserted into a cell and current injected through the electrode so as to hold the cells membrane potential at some predefined level. The technique can be used with separate electrodes for voltage sensing and current passing, for small cells, the same electrode can be used for both. Voltage clamp is a powerful technique for the study of ion channels. See: patch clamp. (18 Nov 1997) |
| voltage gated ion channel | <physiology> A transmembrane ion channel whose permeability to ions is extremely sensitive to the transmembrane potential difference. These channels are essential for neuronal signal transmission and for intracellular signal transduction. See: sodium channel. (18 Nov 1997) |
| voltage gradient | <physiology> Literally, the electric field in a region, defined as the potential difference between two points divided by the distance between them. Used more loosely, the potential difference across a plasma membrane. (18 Nov 1997) |
| voltage loop | <radiobiology> A wire which encircles the main axis of a tokamak in the vicinity of the vacuum vessel. The voltage induced in this loop during the shot is a measure of the ohmic heating voltage induced by transformer action and applied to the plasma. (09 Oct 1997) |
| voltage-gated channel | A class of ion channel's that open and close in response to change in the electrical potential across the plasma membrane of the cell; voltage-gated Na+ c.'s are important for conducting action potential along nerve cell processes. (05 Mar 2000) |

| voltaic | 1. Of or pertaining to Alessandro Volta, who first devised apparatus for developing electric currents by chemical action, and established this branch of electric science; discovered by Volta; as, voltaic electricity. 2. Of or pertaining to voltaism, or voltaic electricity; as, voltaic induction; the voltaic arc. See the Note under Galvanism. Voltaic arc, a luminous arc, of intense brilliancy, formed between carbon points as electrodes by the passage of a powerful voltaic current. Voltaic battery, an apparatus variously constructed, consisting of a series of plates or pieces of dissimilar metals, as copper and zinc, arranged in pairs, and subjected to the action of a saline or acid solution, by which a current of electricity is generated whenever the two poles, or ends of the series, are connected by a conductor; a galvanic battery. See Battery, 4, and Note. Voltaic circuit. See Circuit. Voltaic couple or element, a single pair of the connected plates of a battery. Voltaic electricity. See the Note under Electricity. Voltaic pile, a kind of voltaic battery consisting of alternate disks of dissimilar metals, separated by moistened cloth or paper. See 5th Pile. Voltaic protection of metals, the protection of a metal exposed to the corrosive action of sea water, saline or acid liquids, or the like, by associating it with a metal which is positive to it, as when iron is galvanised, or coated with zinc.
