Influence of electromagnetic fields on the emotional behaviour of rats [Russian]


The effects of ultra low power pulse-width + modulation electromagnetic radiation (EMR, power density 10 mc/Wt/cm2, carrying frequency 915 MHz, modulating pulses with frequency 4, 6, 16 and 20 Hz, duration 10 min) on the rat emotional behavior and motor activity in the elevated plus-maze were studied. It was established that EMR (frequency of modulation 4 and 6 Hz) significantly decreased the emotionally negative reactions of anxiety and fear by a factor of 3.7 (p < 0.01) and 4.5 (p < 0.01) correspondingly and increased by a factor of 1.9-2.2 (p < 0.05) exploratory activity. On the contrary EMR (frequency of modulation 20 Hz) significantly increased by a factor of (p < 0.05) emotionally negative reactions of anxiety and fear and decreased by a factor of 1.8 (p < 0.05) the exploratory activity in rats.
