The process of selecting those portions of a wave that exist during one or more selected time intervals or that have magnitudes between selected limits. Also, the application of a specific waveform to perform electronic switching.

In an ICCD camera system, the application of a voltage that switches the image intensifier on and off in very short intervals. Gating improves temporal resolution.

In an ICCD camera system, the application of a voltage that switches the image intensifier on and off in very short intervals. Gating allows capture of transient events.

The opening and closing of neural channels, facilitated by the interaction of receptors and neurotransmitters, proteins and enzymes.

is the active transition of an ion channel from an open to a closed state

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). It always involves a change in the shape of the protein (called "allosterism").

The opening in lever tumblers which permits actuation of the bolt.

Gating is a type of punishment similar to a detention used typically at educational institutions, especially boarding schools. Precisely what a gating consists of and the rules surrounding it will vary between institutions, but the common element is that someone who has been gated is not permitted to leave the establishment. The word is used as both a noun and a verb.

The use of electric circuits in radar to eliminate or discard the target signals from all targets falling outside certain desired range limits.

The use of an electronic signal from the pumping of the heart to obtain images of heart contractions.

(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.

timing the acquisition of MR data to physiological motion in order to minimize motion artifacts (e.g., cardiac gating, respiratory gating).
