Abstract The frequency spectra (0–26 Hz) of electrograms (EG) of the preoptic region of the hypothalamus were studied in chronic experiments on nine awake rabbits under the influence of nonthermal millimeter-band (55–75 GHz) electromagnetic fields on various acupuncture points: I) the auricular “heart” point (after F. G. Portnov); II) the cranial acupoint (TR-20; the “hypothalamus” point after R. Voll); and III) the “longevity” acupoint (E-36). Irradiation of point I was accompanied by significant suppression of hypothalamic electrical activity at 5 and 16 Hz and enhancement at 7–8, 12, and 26 Hz. Irradiation of point II had similar but less-prominent effects at 7–8 and 12 Hz. Minimal EG changes were observed with exposure of point III. The probabilities of significant changes in EG spectra for irradiation of points I, II, and III were, respectively, 31%, 21%, and 5% (p〈0.05, U-criterion). These results suggest that acupuncture points I and II are more sensitive to millimeter-band radiation than is point III. The presence of individual characteristics of the effects and their change after stress to sign inversion were shown in rat experiments in which the acupuncture points were irradiated.
