SPECTRAL CHARACTERISTICS OF THE ELECTRICAL BRAIN ACTIVITY OF RABBIT AT HUNGER DOMINANT

By means of daily alimentary deprivation the dominant of hunger was created in rabbits. In response to acoustic stimuli summational swallowing and chewing movements appeared, Spectral analysis of the electrical brain activity showed the presence of primary dominant focus zone (lateral and ventromedial hypothalamus), characterized by an increase of spectrum power in delta-range while in the orbito-frontal, sensorimotor, parietal cerebral cortex, in the medial and lateral preoptical hypothalamic zones the power of biopotentials spectrum decreased within the whole analyzed frequency range.
