Aim of study (acc. to author)

To study whether mobile phone exposure causes changes in behavior of rats in the elevated plus maze.

Background/further details

The animals were divided into two groups of six rats each: control group and exposure group. Three of the exposed rats were tested one hour after the last exposure while the other three were tested 24 h after exposure. Controls were tested along with the 24 h post exposure group.

Main outcome of study (acc. to author)

The preliminary data indicated that the mobile phone exposure induced behavioral changes in rats, expressed as a deficit in open arm exploration in the elevated plus maze. Additionally, the number of defecation pellets of exposed animals was increased compared to control animals.
