Ra. Pavlygina et Yv. Lyubimova, SPECTRAL CHARACTERISTICS OF RABBITS BRAIN ELECTRICAL-ACTIVITY IN THE STATE OF HUNGER, Zurnal vyssej nervnoj deatelnosti im. I.P. Pavlova, 44(1), 1994, pp. 57-64
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.
