Changes in the electrical activity of the rabbit's cerebral cortex resulting from exposure to a UHF electromagnetic field

Summary

It was shown in experiments on 40 rabbits that during the three minute action of the UHF electromagnetic field with the intensity of about 1000 V/m on the animal's head, a rise of the amplitude and reduction of the frequency of potentials in the EEG was observed in 47% of the cases. After the action of a strong UHF field (about 5000 V/m), in 80% of the cases a similar EEG reaction was noted. The majority of reactions had an average latent period of 40 sec; reaction with an average latent period of 87 sec occurred more rarely. The after effect lasted for 10–15 min. During the action of the weak UHF field, the excitation of the cortical end of the visual analyzer rose.
