Exposure to 900MHz microwave fields significantly decreased GluR2 protein and increased intracellular calcium in postnatal rat cortical neurons.

Plain English Summary

Summary written for general audiences

Researchers studied the effect of 900MHz low-intensity microwave fields on AMPA GluR2 protein and intracellular calcium in postnatal rat cerebral cortical neurons. Neurons were exposed to continuous 900MHz microwaves at SAR values of 3.22, 2.23, and 1.15 W/kg for 2 hours per day over 4 or 6 consecutive days, and also for 12 hours at 3.22 W/kg. Compared with sham exposure, GluR2 protein was significantly down-regulated and intracellular calcium was significantly up-regulated in the exposed neurons.

Why This Matters

The authors concluded that microwave effects accumulate, show dose-response trends, and should be classified as athermal effects of EMF. The exposures were performed to examine the effect of microwaves on GluR2 protein and intracellular calcium ions.
