  • Title: Simulation study on effects of channel noise on differential conduction at an axon branch.
    Author: Horikawa Y.
    Journal: Biophys J; 1993 Aug; 65(2):680-6. PubMed ID: 7693002.
    Abstract:
    Effects of membrane channel noise (random opening and closing of ion channels) are studied on spike conduction at a branching point on an axon. Computer simulation is done on the basis of a stochastic version of the Hodgkin-Huxley cable model, into which the channel noise is incorporated. It is shown that the channel noise makes conduction of spikes into daughter branches random; spikes randomly succeed or fail in conduction into daughter branches. The conduction is then randomly differential even though the forms and properties of daughter branches are the same. The randomness is considerable when the radius of an axon is small (approximately 1 microns).
