NettetSince the theoretical membrane conductance curves differ significantly from the experimental ones, further experimental analysis of ionic currents with … NettetThe breakthrough of Hodgkin and Huxley was that they succeeded to measure how the effective resistance of a channel changes as a function of time and voltage. Moreover, they proposed a … NettetThis means that unlike simple time delay systems , the Hodgkin–Huxley neuron the inertia is non-linear and the inertia coefficient depends on the signal amplitude and shape. In particular, a decrease in ε with an increase in k should be the result of more narrow impulses in the group for larger k values. ウイキョウ 香り

Nettet4. des. 2014 · The classical Hodgkin-Huxley (HH) model neglects the time-dependence of ion concentrations in spiking dynamics. The dynamics is therefore limited to a time scale of milliseconds, which is determined by the membrane capacitance multiplied by the resistance of the ion channels, and by the gating time constants.
