Abstract

In experiments on alert rabbits it was shown with the help of correlational-spectral method that the rearrangement in the spatial organization of the activity of the first and the fifth layers in the visual and motor cortical zones during orienting reflex and high-frequency stimulation of reticular formation nuclei (NRP and NRT) is of the same type. The synchroneity in the activity of motor zone layers and the fifth layers of different areas increases in parallel. At the same time in the spectra of layer activity high-coherence theta-rhythm increases simultaneously. The data obtained permit to assume that specific rearrangement in the synchroneity of biopotentials of the studied layers during orientation reflex is due to influences of the reticular formation. The effect of mammillary bodies stimulation proved to be less effective.
