It was revealed that the millimeter wave bioresonance therapy improved the condition of experimental animals, accompanying by diminution of licking reaction. Effect of 10 min irradiation was more demonstrative than 3 min. Stimulation with frequency of 61 GHz suppressed licking reaction more deeply than 43 GHz. Most beneficial effects have been found when minimal (0.1 mW/cm²) intensity of electromagneticstimulation was applied.
