Effect of prenatal exposure to mobile phone on pyramidal cell numbers in the mouse hippocampus: a stereological study. med./bio.

Published in: Int J Neurosci 2009; 119 (7): 1031-1041

Aim of study (acc. to author)

To investigate the effect of a prenatal GSM mobile phone exposure on the developing hippocampus.

Background/further details

Pregnant mice were exposed and after delivery their offspring were exposed. A sham exposure group was kept in the same conditions but without exposure. At the 21st day after birth five female offspring from each group were sacrificed.



Exposure Parameters
Exposure 1: 890–915 MHz
Modulation type: pulsed
Exposure duration: 12 hr/day for 19 - 20 days (gestation period) + 20 days after birth (female offspring only)
