title: [Regional features of the electrical activity of the neocortex in the dog over a wide range of frequencies].
abstract: Autospectral characteristics (ASC) of potentials of different neocortical areas of dogs in a state of quiet wakefulness were studied in a wide frequency band (1-100 Hz) by means of correlation-spectral analysis. A transition from evaluation of the mean power tendencies to a construction of distributions of different power levels for each of five arbitrarily chosen frequency bands permitted to reveal regional differences in ASC of each animal as well as interindividual EEG distinctions. The regional differences observed in all frequency bands (though not equally expressed) including the higher ones indicate not only the informativity of high-frequency components of electrical neocortical activity but also their neuronal origin.
