Which of the following was not one of the features of Hodgkin and Huxley's mathematical model?



  1. The action potential can be reconstructed based entirely upon the time course and amplitudes of the ionic conductances.
  2. The fast-rising phase can be accounted for by selective sodium entry.
  3. The model mimics the experimentally measured refractory period.
  4. The falling phase can be at least partially accounted for by the activation time course of the potassium current.
  5. The undershoot can be accounted for by the time course of sodium current reactivation.

Answer: 5
