LETTER TO THE EDITOR: Multifractal distribution of spike intervals for two oscillators coupled by unreliable pulses

Two neurons coupled by unreliable synapses are modelled 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 covering, information and correlation dimensions are calculated as a function of synaptic strength and transmission probability.
