[Wiener analysis of transmission of signals of identified mollusk neurons].
Mathematical model of spike train transmission by identified neurons of the mollusc Planorbis corneus was obtained by means of Wiener analysis. Poisson distributed sequences of near-threshold stimuli were used as input trains for construction and testing. It was shown that addition of terms sensitive to the nonlinear properties of the synapse-neuron system to the model decreased the model error from 25% to 16%. When comparing the mean square error value of the predicted model responses to testing stimuli and the real neuron responses to the same stimuli, the prediction error with allowance for nonlinear properties was established not to exceed 21%. Some questions connected with choosing adequate criteria for comparing model and experimental results are discussed.
