AB  - The effects of short-term (15 min) pre-exposure of rats to extremely low-frequency magnetic field (ELF-MF, 50 Hz, 6 mT) on their motor (locomotor and stereotypic) activity induced by D-amphetamine sulphate (AMPH) at different doses (0.5, 1.5 and 4.5 mg/kg, i.p.) were studied in the open field test. In saline-treated rats both parameters of motor activity were unaffected by ELF-MF irradiation. The rats pre-exposed to ELF-MF and injected with the lowest dose of AMPH showed the same locomotor activity as control animals, while their stereotypic behaviour was significantly elevated. ELF-MF in combination with AMPH at higher doses significantly enhanced motor activity when compared with values obtained in both control and combined experiments with the lowest dose of the drug. However, only combined locomotor effect at the middle dose of AMPH was significantly greater than those observed in corresponding experiments with AMPH alone. These results demonstrate that acute short-term exposure to ELF-MF is able to modify a motor activity in dependence on the extent of AMPH-induced neurotransmitter imbalance.

AB  - Purpose: To compare in the electroencephalogram of rats the effects of scopolamine (an acetylcholine receptor antagonist) alone and after repeated exposure to low‐level microwaves modulated at extremely low frequency. Materials and methods: Averaged frequency spectra (0.5–30 Hz) of the electroencephalogram were studied in freely moving rats with carbon electrodes implanted into the somatosensory cortex. The rats were repeatedly (3 days, 30 min day−1) exposed to low‐intensity
(≅0.3 mW cm−2) microwaves (915 MHz, 20‐ms pulse duration), amplitude modulated (square‐wave) at extremely low frequency (4 Hz). Results: The exposure to extremely low frequency microwaves alone significantly enhanced the fast electroencephalographic rhythms (18–30 Hz). This effect was observed neither in subsequent sham‐exposure experiment nor in radiation‐naïve animals. In the microwave‐exposed rats, scopolamine
(0.1 mg kg−1, subcutaneously) did not cause a slowing in the electroencephalogram that was shown in non‐exposed rats. A similarity between the scopolamine‐induced electroencephalogram effect in the microwave‐exposed rats and that of physostigmine (enhancing the acetylcholine level in the brain) in radiation‐naïve animals was noted. 
This paradoxical phenomenon stimulates new experimentation for understanding its mechanism(s). Conclusions: The data obtained provide additional evidence that repeated low‐level exposure to extremely low frequency microwaves can modify an activity of cholinergic system in the brain.

AB  - Changes in the behavior of Morimus funereus individuals were investigated as early manifestations of the contact of a living system with a changed environment primarily established via the nervous system. These experiments were aimed at revealing possible behavioral differences of a laboratory population of cerambycid beetle M. funereus in an "open field" before and after exposure to an extremely low frequency magnetic field (ELF-MF, 50 Hz, 2 mT). The experimental groups were divided into several activity categories and exposed to ELF-MF. The results showed that the activity increased in the groups with medium and low motor activity, but decreased in highly active individuals. High individual variability was found in the experimental groups, as well as differences in motor activities between the sexes, both before and after exposure to ELF-MF. According to preliminary results, we assume the changes of activity in both sexes after exposure to ELF-MF. The results showed a tendency toward locomotor activity decrease, the affect being more pronounced in females. As opposed to this type of activity, stereotypic activity of males was increased after the exposure, whereas females maintained the expected tendency of decrease. However, we did not obtain statistically significant differences because of a high individual variability and a low total number of individuals in the experiment (N = 28). Only a detailed analysis of the locomotor activity at 1-min intervals showed some statistically significant differences in behavior between the sexes.
