| gating | 1. In a biological membrane, the opening and closing of a channel, believed to be associated with changes in integral membrane proteins. 2. A process in which electrical signals are selected by a gate, which passes such signals only when the gate pulse is present to act as a control signal, or passes only the signals that have certain characteristics. See: gate. (05 Mar 2000) |

| 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) |
| gating mechanism | Occurrence of the maximum refractory period among cardiac conducting cells approximately 2 mm proximal to the terminal Purkinje fibres in the ventricular muscle, beyond which the refractory period is shortened through a sequence of Purkinje cells, transitional cells, and muscular cells; gating mechanism may be a cause of ventricular aberration, bidirectional tachycardia, and concealed extrasystoles, a mechanism by which painful impulses may be blocked from entering the spinal cord. Compare: gate-control theory. (05 Mar 2000) |
| cardiac gating | Using an electronic signal from the cardiac cycle to trigger an event, such as in imaging separate phases of cardiac contraction. (05 Mar 2000) |

| channel gating | <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) |
| ion channel gating | The opening and closing of ion channels due to a stimulus. The stimulus can be a change in membrane potential (voltage-gated), drugs or chemical transmitters (ligand-gated), or a mechanical deformation. Gating is thought to involve conformational changes of the ion channel which alters selective permeability. (12 Dec 1998) |
| gating |
(Or range gating.) The use of digital or electrical methods in radar to eliminate or reject the target signals from all targets that are outside certain range limits. Such methods make it possible to measure properties of the echoes from particular targets without interference from the signals returned from closer or more distant targets.

| gating |
Process by which ion channels open and close their pores. Some, such as voltage-gated ion channels, open and close depending on the electrical potential of the cell membrane. Others depend on such factors as cell volume, intracellular metabolic state (ATP concentration, etc), intracellular ligand and/or second messenger presence (Calcium, cyclic AMP due to light, etc), and extracellular ligands (neurotransmitters like acetylcholine, GABA). ...
