Simulation of myelinated neuron with focus on conduction speed

In this study, we have shown that myelination and dendritic structure are responsible for the occurence of DAP and HAP which are in turn responsible for altered threshold of subsequent action potential. We have quantatatively shown that the threshold is different depending on the timing of subsequen ...
