title: [Patterns in the restructuring of EEG frequency spectra].
abstract: A study was made of changes in the spectrum of brain electrical activity of rabbits, due to changes in the functional state of the brain, induced by means of a smooth rise in CO2 concentration in the air inhaled by the animals. Transformation of the general spectral characteristics has been revealed which consists in simultaneous re-distribution of frequency ranges and changes in the proportion of alpha-like, theta- and sigma-rhythms.
