Ionotropic effect

Source: Wikipedia, the free encyclopedia.

An ionotropic effect is the effect of a transmitter substance or hormone that activates or deactivates

ionotropic receptors (ligand-gated ion channels). The effect can be either positive or negative, specifically a depolarization or a hyperpolarization respectively. This term is commonly confused with an inotropic effect, which refers to a change in the force of contraction (e.g. in heart muscle
) produced by transmitter substances or hormones.

Examples

This term could be used to describe the action of

GABAa receptors
