    Abstract:
    Interaction of neurons with tonic response to sound with adjacent or distant (approximately 400-500 micrograms) cortex neurons was studied in acute experiments on 15 immobilized cats using a method of the cross-correlation analysis. A presence of synchronizing excitatory input common for the cells has been revealed in 26 pairs (72%) on the cross-correlograms. The results of the cross-correlation analysis in five pairs of neurons show mono- or polysynaptic excitatory effect of a tonic neuron to impulse activity of another neuron. Negative correlation indicative of the inhibitory influence of tonic neurons on impulse responses of other neurons of the same or adjacent auditory cortex column is revealed in five pairs of neurons, but the inhibitory influences may be considered as monosynaptic ones only in 3 pairs of these neurons (latency of interaction 1.0-1.5 ms). The data obtained permit concluding that the group of neurons characterized by tonic response to sound is a heterogeneous one in the functional respect. An assumption that some neurons of the tonic type are inhibitory interneurons of the auditory cortex, other excitatory ones is under discussion.
