The effects of prenatal exposure to a 60 Hz magnetic field on the serotonin content in the cerebral cortex and pineal gland in young rats should be investigated.
Pregnant rats were divided into 3 groups (n=10 each): 1) exposure to the magnetic field, 2) sham exposure and 3) cage control. The offspring was killed and examined after 0, 15, 21 and 61 days after birth.

|Sham exposure||A sham exposure was conducted.|
A significant increase of the serotonin content was found in the cerebral cortex of exposed animals compared to the control group after 0, 15 and 21 days after birth. (Remark EMF-Portal: These are the results as they are described in the abstract and running text. The figures are partly contradictory and not clear. Moreover, a potential significance of the differences between the exposure and sham exposure group is not stated or shown clearly.)
All other parameters were not significantly different between the groups.
The authors conclude that prenatal exposure to a 60 Hz magnetic field might increase the serotonin content in the cerebral cortex of newborn rats.
