For example, the shorter chronaxy of myelinated motor neurons compared with that of unmyelinated fibers of the myocardium allows safe stimulation with short pulses during artificial respira-tion.

Webchro·nax·ie ( krō'nak-sē ), A measurement of excitability of nervous or muscular tissue; the shortest duration of an effective electrical stimulus having a strength equal to twice the minimum strength required for excitation. Synonym (s): chronaxia, chronaxis, chronaxy [G. chronos, time, + axia, value] Chronaxie is the tissue-excitability parameter that permits choice of the optimum stimulus pulse duration for stimulation of any excitable tissue. Chronaxie (c) is the Lapicque descriptor of the stimulus pulse duration for a current of twice rheobasic (b) strength, which is the threshold current for an infinitely long … See more Chronaxie is the minimum time required for an electric current double the strength of the rheobase to stimulate a muscle or a neuron. Rheobase is the lowest intensity with indefinite pulse duration which just stimulated muscles … See more The terms chronaxie and rheobase were first coined in Louis Lapicque’s famous paper on Définition expérimentale de l’excitabilité that was published in 1909. The above I(d) … See more The main value of chronaxie is comparing excitability across different experiments and measurements using the same standard, thus making data comparisons easier. Electrical stimulation based on chronaxie could regulate myoD gene expression in … See more • Bursting • Calcium channels • Epithelial sodium channel • Ion channels See more An electrode is inserted into the muscle of interest, which is then stimulated using surface current. Chronaxie values increase resulting from hyperventilation can be ascribed to a … See more Chronaxie is increased in the tetany of hypoparathyroidism. It must be remembered, however, that it is the rheobase which corresponds to the x.c.c. of electrical … See more Acute intoxication of rats with aldrin decreases chronaxie, whereas chronic exposure to this chlorinated hydrocarbon insecticide has the reverse effect. Chronic exposure of rats to the closely related epoxide, dieldrin, has been suggested to reduce their … See more
