| Abstract: | Form of auto- and cross-correlation histograms of impulse trains of two neurones with a common monosynaptic input from the third one were studied by methods of modelling of neuronal interaction--biomathematical (computer controlled experiment on molluscs neurones) and mathematical--in wide physiological ranges of values of parameters characterizing properties and conditions of functioning of neurones and synapses. In conditions typical of the central nervous system of mammals (but not invertebrates), when neurones are subjected to intensive random afferent synaptic bombardment and reveal no pace-maker properties, each of the possible type of common monosynaptic inputs to two neurones--excitatory, inhibitory or inhibitory-excitatory--is manifestated in cross-correlation histogram of their impulse trains in a specific way. |
