Stochastic Dependency of Neural Impulse Sequences

Abstract

The statistical dependent properties of the spontaneous impulse sequence recorded from the mesencephalic reticular formation (MRF) and the lateral geniculate nucleus (LGN) in cats were clarified with the following procedures. 1) the value of each interspike interval was normalized by the mean value of the intervals. 2) the stochastic dependency of the normalized sequence was calculated. It is suggested that Markov property exists in the spontaneous impulse sequences recorded from MRF single neurons and not from LGN single neurons.
