研究目的(著者による)

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

詳細情報

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.
