Aim of study (acc. to author)

To study the effect of an extremely low frequency magnetic field on different parameters of spontaneous and amphetamine-induced motor activity.

Background/further details

Five groups of male rats (five rats per group) were investigated: two exposed (with and without amphetamine solution) and three sham-exposed (with/without amphetamine solution or saline solution) groups.

Main outcome of study (acc. to author)

Exposure to extremely low frequency magnetic field for seven days did not change spontaneous motor activity of exposed rats compared to sham exposed animals. Exposure to extremely low frequency magnetic field decreased locomotor and stereotypic activity induced by amphetamine and accordingly increased the resting time of exposed animals compared to sham exposed and amphetamine alone-treated animals.
The data indicate that a extremely low frequency magnetic field has different effects on some parameters of amphetamine-induced motor activity.
