Organization and dynamics of interactions in local neural networks of the visual cortex

The goal of the present investigation was the study of the organization and dynamics of intracortical interactions in local neural networks (LNNs) of the guinea-pig visual cortex (VC). The spatial distribution of neuron interactions in the tangential plane of the guinea-pig VC is demonstrated, and a nearly complete disappearance of excitatory and inhibitory interactions between neurons separated by 250 microns is observed. It was found that a change in the LNN VC functioning led to a change in the intensity and temporal dynamics of the responses, as well as to a change in the synchronization of the neuron activity in local groups. Evidently this process caused the overswitching of the operating regime of the neuron group as a whole
