The effect of mobile phone on the number of Purkinje cells: a stereological study. med./bio.

Published in: Int J Radiat Biol 2010; 86 (7): 548-554

Aim of study (acc. to author)

To study the effect of exposure to a mobile phone on the number of Purkinje cells and granule cells in the developing cerebellum after whole gestation exposure of pregnant mice.

Background/further details

Seven pregnant mice and a total of 66 female offspring (obtained after delivery) were exposed. A sham exposed control group (number of animals not given) was also used. At the 21st day after birth, six female offspring selected randomly from each group (exposed and sham exposed) were investigated.
Remark of EMF-Portal editor: It is not clearly stated in the article whether the 66 pups are exposed only during their prenatal phase (within their dams) or for additional 20 days after delivery.

Main outcome of study (acc. to author)
