[An electrophysiological evaluation of the role of the olfactory analyzer in brain integrative activity].

Summary electrical activity of olfactory bulb and amygdala of unrested rats with reversible anosmia during conditioning with application of light and odor as conditioned stimuli was studied. It was shown, that recovery of capacity for reception of odor wasn't connected with appearance in electrical activity of investigated structures of high-frequency high-amplitude components. Additional investigations of neuronal isolation of olfactory bulb and discovery of correlative changes of power of high-frequency components in dependency on level of common excitation give the possibility to consider this rhythm as one of the mechanisms of nonsensory modulator influences of olfactory analyser.
