Multifractal distribution of spike intervals for two neurons with unreliable synapses — •Wolfgang Kinzel and Johannes Kestler — Theoretical Physics, University Würzburg

Two neurons coupled by unreliable synapses are modeled by leaky integrate-and-fire neurons and stochastic on-off synapses. The dynamics is mapped to an iterated function system. Numerical calculations yield a multifractal distribution of interspike intervals. The Haussdorf, entropy and correlation dimensions are calculated as a function of synaptic strength and transmission probability.
