Action potential propagation and synchronisation in myelinated axons
Fig 9
Ephaptic coupling reduces AP speed and leads to AP synchronisation.
A: Depolarisation curves for a pair of action potentials with initial offset of 0.02ms converge, reducing the time difference between action potentials. B: Depolarisation of a synchronous pair of action potentials is slower than for a single action potential. C: An action potential induces initial hyperpolarisation and subsequent depolarisation in an inactive neighbouring axon. Parameters: standard parameters, .
