[Effect of coagulation of the reticular formation in the region of the NRP and NRT nuclei on the spread of brain biopotential synchronization in rabbits].

The influence of coagulation of NRP and NRT nuclei on the level of spatial synchronization of bioelectrical activity in the visual and motor cortical areas was studied in chronic experiments on alert rabbits. It was shown that elimination of these structures from activity diminishes the correlation of processes in the studied zones. The degree of the coagulation effect depends on the volume of destruction and on the degree of synchroneity of the background neocortical biopotentials. Destruction of the nuclei is attended with dominance of delta-frequencies in the power spectra and a drop of coherence function in the theta range. It is assumed that the NRP and NRT nuclei are functional links of the integral system which controls the level of spatial synchronization of bioelectrical processes in the rabbit cerebral cortex.
