N2 - It has been revealed in our recent study that cortical neurons are categorized into distinct types, according to a new measure of the local variation of inter-spike intervals, L V. In this paper, we obtain values of the local variation L V and a conventional coefficient of variation C V for a variety of model point processes. While the value of C V undergoes large changes by rate fluctuation of the point processes, the value of L V does not undergo large changes by rate fluctuation, and is principally determined by the form of intrinsic interval distribution of the original model point process.
