WebHere is a picture of a theoretical strength-duration curve copied from the wiki page on rheobase. [NB: I find the wiki page needlessly complicated]. The rheobase is the horizontal asymptote. An often used parameter to characterize the function is chronaxie, which is the pulse duration equivalent to two times the rheobase. WebElectrical signals are used extensively within the human body to transfer information from one point to another. The signals travel through the nervous system and muscle fibers in what are known as excitable cells. The biopotentials are produced as a result of interactions between electrical and chemical activities. Electrically, a cell exhibits an ionic voltage, a …

WebHow Chronaxie and Rheobase are related to the action potential? The chronaxie is the time it takes to activate a fiber when the amplitude is twice the rheobase. For two neurons with similar rheobases, the chronaxie gives a measure of the relative excitability of the neurons: shorter chronaxies apply to neurons that are more excitable. WebDefinieren Sie Rheobase, Chronaxie, und Akkomodationsschwellenwert. A Die Rheobase entspricht die Stromstärke von ein Rechteck Impuls von 1000ms Impulsbreite, welche eine Minimalzuckung hervorruft.
