which leads to a constant-charge approximation. Interestingly, the latter may fit well also more complex models of the excitable membrane, which take into account ion-channel gating mechanisms, as well as intracellular current flow, which may be the main contributors for deviations from both simple formulas. These `subtleties` are clearly descri.....

(kro´nak-se) chronaxy (kro´nak-se) the minimum time at which an electric current must flow at a voltage twice the rheobase to cause a muscle to contract. In a strength-duration curve for muscle stimulation, it is the pulse width at a voltage twice that at the rheobase.
