[The spectral characteristics of the electrical activity of the rabbit brain in a state of hunger].
Brain electrical activity of rabbits in the state of hunger, induced by food deprivation, was processed by spectral analysis using FFT algorithm. State of hunger lead to complex pattern of electrical activity modification: i.e., enhancement of the low-frequency band spectral power in the lateral hypothalamus and decrease of the spectral power of potentials of orbitofrontal, sensorimotor cortices, medial preoptic zone, ventromedial hypothalamus. One-day food deprivation produced interhemispheric asymmetry of neocortical electrical activity due to greater decrease of the spectral power of in the left hemisphere.
