Chronaxie und rheobase

WebJun 1, 2013 · Rheobase is measured as the threshold stimulus current for an active response with a long-duration pulse and chronaxie is the pulse width at twice the rheobase threshold current 14, 15). However ... 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.
