[EEG spectral analysis in the hunger dominant in man].

[Article in Russian]


EEG spectral characteristics were studied in the states of satiation, short-term food deprivation, and hunger dominant in 10 healthy right-handed subjects. The dominant of hunger was created at the background of short-term food deprivation by using sensory stimuli. Appearance of the swallowing movements in response to the applied stimuli was a criterion of dominant formation. Both food deprivation and hunger dominant were associated with a decrease of the EEG spectral power in the delta range and its increase in the alpha range. Food deprivation, additionally, was accompanied by an increase of the spectral power in the theta 2 range. Apart from the spectral changes, reduction of the alpha-rhythm frequency was observed in the states of food deprivation. This phenomenon was absent in the dominant state. In the states both of food deprivation and hunger dominant, EEG spectral characteristics, predominantly, changed in the left hemisphere, especially, in the alpha- and delta-ranges.
