[The effect of low-frequency stimulation of the diencephalon on the topogram of cortical potentials in freely moving rabbits].

The spatio-temporal organization of the cortical potentials in rabbits was investigated by means of comparison of successive electroencephalotopograms. This systemic organization was characterized by the potentials' sagittal gradient and its inversion within the 4-6/sec range due to higher amplitudes in the frontal cortical areas, - during natural transition from the active to passive behavior as well as after low-frequency stimulation of the thalamic midline nuclei and of the hypothalamic supraoptic area. Single stimuli applied to the structures under study ordinarily prevented any obvious active behavioral periods, although entailed no long-lasting changes in the rest-activity dynamics.

Investigation of the functional role of the septum.

A spectral-correlation analysis was made of the EEG recorded from the motor and visual cortex, hippocampus, and septum (in some series of experiments, the lateral geniculate body and mesencephalic reticular formation also) of rabbits in the presence or absence (background) of sensory stimulation. To investigate the functional role of the septum as a pacemaker the method of "rhythm binding" by electrical stimulation of the septum (lateral and medial nuclei) was used. By electrical stimulation of the medial nucleus of the septum at a frequency of 4-30 Hz rhythm binding was successfully obtained in all regions studied. Maximal rhythm binding was observed in cortical potentials. It is postulated that cortical rhythmic activity is generated as a result of physiological interaction between cortex and septum.
