title: Hypothalamic effects of millimeter wave irradiation depend on location of exposed acupuncture zones in unanesthetized rabbits.
abstract: On nine unanesthetized male rabbits, the frequency spectra of hypothalamic electrogram (EEG) were studied during low intensity (10 mW/cm2) millimeter wave (55-75 GHz) exposure to various acupuncture points (zone): auricular, cranial and corporal. The chances of occurrence of significant (p < 0.05) changes in the EEG spectra during irradiation versus, sham experiments were equal to 31, 21 and 5%, respectively. Exposure to auricular zone reduced the EEG power in narrow bands with central frequencies of 5.3, 15.9 Hz and increased ones of 2.6, 3.2, 6.9, 7.9, 11.5 and 25.6 Hz. The main effect of exposure to cranial zone was similar--changes at 15.9 and 25.6 Hz only. The data obtained demonstrate that the responsiveness of the central nervous system to low intensity millimeter wave radiation may depend on the location of the exposed acupuncture zone.
