[A coherence analysis of the electrical activity of the rabbit brain during the creation of a "polarization" hunger dominant].
In the process of formation of "polarization" hunger dominant under the action of weak direct current on the structures of lateral hypothalamus and sound stimulation, the coherence between the potentials of the right parietal cortical area and the frontal areas of both hemispheres increases in the low-frequency band. At the same time, the coherence between electrical activity led from the other cortical areas under study decreased. An increase in coherence is observed between the potentials led from the lateral hypothalamus and frontal cortical areas of both hemispheres in contrast to a decrease in coherence between the electrical activity of the lateral hypothalamus and parietal cortex. Coherence between potentials recorded in the ventromedial hypothalamus and electrical activity of all the studied cortical areas increases (mainly, in the low-frequency range).
