SPECTRAL CHARACTERISTICS OF RABBITS BRAIN ELECTRICAL-ACTIVITY IN THE STATE OF HUNGER

Brain electrical activity of rabbits in the state of hunger, induced b y food deprivation, was processed by spectral analysis using FFT algor ythm. State of hunger lead to complex pattern of electrical activity m odification: i. e., enhancement of the low frequency band spectral pow er in the lateral hypothalamus and decrease of the spectral power of p otentials of orbitofrontal, sensorimotor cortices, medial preoptic zon e, ventromedial hypothalamus. One-day food deprivation produced interh emispheric asymmetry of neocortical electrical activity due to greater decrease of the spectral power of in the left hemisphere.
