Abstract A digital-computer simulated model, which consisted of the neuromuscular synapse and the muscle with external loads, was formulated for the neuromuscular system of the claw opener muscle of the crayfish. By using this model, the relationship between stimuli with correlated adjacent interval sequences and responses was investigated. The imposed correlated sequences generated by the three-state semi-Markov process, with the mean rate, interval distribution and variance held constant, were the following three types: Type I, a positive correlated sequence; Type II, a first order negative correlated sequence; Type III, an independent sequence of the above two. As a result of the model study, it was found that the evoked response by a Type I sequence is maximum among them, which agrees very well with the experimental result obtained from the claw opener muscle in the previous paper. In addition, the response by Type II sequence fluctuates least about its moving average or ensemble mean value at a time although the response is of small magnitude, which also coincides with the experimental results and in part with Birk's model study. The fluctuations about ensemble mean value were evaluated by using the average mutual information for various mean values of stimuli.
