Model 2450 MHz (CW) exposure to rats and analysis of brain biochemistry

Wistar rats were exposed to 2450 MHz (CW) microwaves for 1 hour at a power density of 10 mW/cm2 and analyzed for regional brain contents of noradrenaline (NA), serotonin (5HT), dopamine (DA), and their main metabolites using HPLC. Exposures increased core temperature of the rats by 3-4 degrees. Exposure resulted in a significant decrease in NA in the hypothalamus, increased DOPAC (deaminated and dehydrogenated DA forming 3, 4-dihydroxyphenylacetic acid) in the pons / medulla oblongata, increased DA turnover in the striatum, and increased 5HT turnover rate and total amount in the cortex. The authors suggest these results might be explained by the physiological response to heat stress caused by the hyperthermic effects of the microwaves, although the possibility of a direct effect cannot be eliminated
