Differential effects of magnetic field exposure from domestic power supply on loco motor and exploratory behavior of an adult rat

In the present study, we have examined the low intense magnetic field exposed on adult rats to understand effect of several behavioral parameters. The rats are tested in the open field and spontaneous alternation task after either a single or chronic exposure to the magnetic field. We found that magnetic field exposure had no effect on locomotor behavior in the adult. However, the exploratory behavior of adult rats in the open field was significantly affected. Indeed, we found a consistent increase in behavior performance viz. exploration time and number of exploration events in rats exposed to magnetic field. Our results demonstrate behavioral changes after magnetic field exposure in adult subjects. This also suggests possible deleterious effects of magnetic field exposure in the brain. (author)
