Chronaxie und rheobase

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. Webrheobase: [ re´o-bās ] the minimal electric current of infinite duration necessary to produce a twitch in a muscle. In a strength-duration curve for muscle stimulation, it is the voltage at which there is no further decrease in threshold when …
