[Display of a monosynaptic excitatory connection in the structure of a crosscorrelation histogram].

Reflection of the monosynaptic excitatory connection in the cross correlation histogram structure was investigated using mathematical model of neuron interactions. The peculiar features of crosscorrelation histogram primary peak waveform and situation permitting distinguishing the monosynaptic excitatory connection from the monosynaptic excitatory shared input were described. Variation of primary peak magnitude with the model parameters describing mechanisms of the action potential generation and synaptic excitation transmission was shown. The autocorrelation histogram structure is shown to be reflected in the crosscorrelation histogram structure on both sides of the primary peak and to take part in the forming of secondary peaks and troughs.
