Abstrakt: The influence of extremely low frequency magnetic field on rats behavior (working memory, learning, social activity) was examined. Rats were exposed to magnetic fields at three different conditions: exposure 1-50 Hz, 46 mT; DC 65 mTl; exposure II-50 Hz, 46 mTl; DC 14-17 mTl; Exposure III-sham. Field related changes were observed after exposure I: the increase of error rate in Y-maze performance, shorter adaptation time in instrumental performance, the decrease of aggression and sociability, enhancement of the defence reactions. Data obtained show that influence of 50-Hz magnetic field depends on the level of DC field. The combination presumably considered as resonant to Ca++ was more effective.
