| bootstrap current | <radiobiology> Currents driven in toroidal devices by neo-classical diffusion. They may amount to a substantial fraction of the net current in a tokamak reactor, thus lengthening the pulse time or decreasing the power needed for current drive. (09 Oct 1997) |
|---|---|
| calcium current | Inflow of calcium ions through specific calcium channels. Critically important in release of transmitter substance from presynaptic terminals. (18 Nov 1997) |
| galvanic current | See: direct current, galvanism. (05 Mar 2000) |
| radio frequency current drive | <radiobiology> Plasma waves in the radio-frequency range can be used to push plasma particles in such a way that current forms in the plasma, this is a method of non-inductive current drive which would allow for steady-state fusion reactors to operate. (09 Oct 1997) |
| gating current | <physiology> Small currents in the membrane just prior to the increase in ionic permeability, due to the movement of charged particles within the membrane. So called because they open the gates for current flow through ion channels. (20 Mar 1998) |
| M current | <physiology> Flow of potassium ions through M channels. (26 Mar 1998) |
| centrifugal current | The direction of current flow in a nerve when the cathode is placed peripheral to the anode, in contrast to ascending current. Synonym: centrifugal current. (05 Mar 2000) |
| centripetal current | The direction of current flow in a nerve when the anode is placed peripheral to the cathode, in contrast to descending current; the convention used is that current flows from positive to negative. Synonym: centripetal current. (05 Mar 2000) |
| chloride current | Flow of chloride ions through chloride selective ion channels. (18 Nov 1997) |
| current | <chemistry> The amount of charge carried per unit time. (09 Jan 1998) |
| current density | <radiobiology> Amount of current flowing through a substance, per unit area perpendicular to the direction of current flow. (See also density) (09 Oct 1997) |
| current drive | <radiobiology> Any of a variety of techniques used to cause current flow in a plasma. See inductive current drive, RF current drive, non-inductive current drive. Usually applied to schemes used to generate current in tokamaks and other toroidal devices which require internal plasma currents. See: bootstrap current. (09 Oct 1997) |
| current of injury | The current set up when an injured part of a nerve, muscle, or other excitable tissue is connected through a conductor with the uninjured region; the injured tissue is negative to the uninjured. Synonym: demarcation current. (05 Mar 2000) |
| halo current | <radiobiology> Currents in the halo region of a plasma discharge. See: halo. (09 Oct 1997) |
| high frequency current | An alternating electric current having a frequency of 10,000 or more per second; it produces no muscular contractions and does not affect the sensory nerves. Synonym: d'Arsonval current, Tesla current. (05 Mar 2000) |
