AL, Hirbec H, Bonnefont X, Privat A, et al. (2004):
The authors studied the effects of RFR on the biochemistry of animals'
brains. They used a heads-only exposure system and the RFR was emitted
at 900 MHz frequency with pulse modulation. The SAR was 6 W/kg. In each
experiment, rats were divided into 2 groups - one exposed to the RFR
for 15 minutes, and one sham-exposed but restrained, also for 15 minutes.
The neurotransmission systems of the brain were studied by examining
the effects of the RFR on the excitatory, inhibitory, and neuromodulatory
communications.
The excitatory
system was studied via the effects on NMDARs, a subtype of glutamate
receptors. The inhibitory system was investigated by GABAA receptors
in the hippocampus. Modulatory systems were studied by examining dopamine
transporters.
NMDARs showed
a significant decrease in the cortex and striatum after exposure.
GABAA receptors decreased in the hippocampus, and Dopamine receptors
decreased in the cortex and increased in the striatum. A strong glial
reaction was observed in the brain on microscopy. The rat general
locomotor function was not altered in the short term.
The authors claim:
"..our results provide the first evidence for rapid cellular
and molecular alterations in the rat brain after an acute exposure
to high power GSM 900 MHz microwaves".
The authors do not believe that the results noted are due to thermal
effects, but base this on experiments on a gel phantom and not on direct
measurement. They state that their experiments should be repeated at
lower power e.g. 2W/kg.
