THE EFFECT OF MICROWAVE IRRADIATION ON THE TURNOVER RATE OF SEROTONIN AND NOREPINEPHRINE AND THE EFFECT ON MONOAMINE METABOLIZING ENZYMES
Solomon H. Snyder · 1971
1971 research investigated whether microwave radiation disrupts brain neurotransmitters that control mood, sleep, and stress responses.
Plain English Summary
This 1971 research investigated how microwave radiation affects brain chemicals like serotonin and norepinephrine, which regulate mood, sleep, and stress responses. The study examined whether microwaves alter how quickly these neurotransmitters are produced and broken down, along with effects on the enzymes that metabolize them. This early work explored potential neurological impacts of microwave exposure decades before widespread wireless device use.
Why This Matters
This pioneering 1971 study represents some of the earliest scientific investigation into how microwave radiation affects brain chemistry. The researchers focused on serotonin and norepinephrine, neurotransmitters that control everything from mood and anxiety to sleep patterns and stress responses. What makes this particularly relevant today is that these are the same frequencies we're now exposed to daily through WiFi, cell phones, and other wireless devices.
The fact that scientists were investigating neurochemical effects of microwaves over 50 years ago underscores how long we've known about potential biological impacts. Yet regulatory agencies continue to focus primarily on heating effects, largely ignoring the growing body of research on non-thermal biological mechanisms. The reality is that your brain's delicate chemical balance could be influenced by the same microwave frequencies that power your wireless devices.

Specific exposure levels were not quantified in this study. Duration: 8 hours/day for 7 days
Study Details
To detect neurochemical alterations in laboratory animals exposed to microwave irradiation at low levels (10 mW/cm²) and to examine the effects on serotonin and norepinephrine turnover rates and related enzymes.
Male rats (150-250 g) were maintained in individual lucite cubicles (5" x 5" x 10") in which air hol...

This investigation has been concerned with the effect of microwave irradiation on the turnover rate of serotonin and norepinephrine in rat brain. There is evidence that microwave irradiation at low levels produces in humans and experimental animals somnolence and irritability. Since the serotonin neuronal system in the brain is known to participate in the regulation of sleep and level of attention, and since brain norepinephrine has been implicated as playing a role in central stimulation, the turnover of these two amines were examined. When rats were acutely exposed for 1 hour to microwave irradiation at 40 nW/cm² there was a significant acceleration of serotonin turnover. Since the body temperature of these animals was elevated by about 3°C, it is possible that this was an effect of "heat stress", a procedure which is known to increase the rate of serotonin turnover. The most striking results of the study were obtained when rats were exposed to low levels (10 nW/cm²) microwave irradiation 8 hours a day for 7 days and were sacrificed 1 day following the last day of microwave exposure. Under these conditions, at the time serotonin turnover was estimated rats had a normal body temperature and showed no apparent behavioral abnormalities. Nonetheless there was a dramatic slowing of serotonin turnover to a rate of 1/4 that of control animals treated identically except for the absence of microwave exposure. This marked decrease in serotonin turnover is the most pronounced effect on the turnover rate of this amine that has been reported following any drug or other treatment to our knowledge. Since serotonin turnover rates presumably reflect the firing rate of the serotonin neurons, this result suggests that the firing of serotonin neurons in the brain is markedly slowed following chronic low level microwave irradiation. Results suggest also that measurement of serotonin turnover is a sensitive tool for detecting effects of low levels of microwave irradiation on brain function.
