[ラットに与えられたUHF電磁界振幅変調パターンとそれによるフラッシュ誘発電位との関係] med./bio.

To investigate whether a reciprocal relationship in the interaction of ultrahigh frequency (UHF) electromagnetic field with CNS exists.

That is, would a continuous wave, nonmodulated UHF electromagnetic field, when applied to electrically rhythmic CNS tissue, develop a dynamic variation in field amplitude in the vicinity of the tissue which would correspond to the electrophysiological frequencies (or waveforms) of the tissue. If such an amplitude modulation effect occurs, it would be an alternative method for recording electrophysiological activity. The relationship between flash evoked potentials and evoked amplitude modulation patterns of an applied UHF electromagnetic field was studied.

Patterns of amplitude modulation of an applied UHF electromagnetic field, when recorded and averaged, show strong correlations with simultaneously recorded evoked potentials. The results support the hypothesis that the UHF electromagnetic field amplitude is altered in a dynamic fashion by the tissue's electrophysiological processes that are involved with the generation of CNS electric fields.
