Low-level microwave irradiation and central cholinergic systems
Unknown authors · 1989
University of Washington researchers exposed rats to pulsed 2.45 GHz microwaves (the same frequency as microwave ovens) and found significant changes to brain chemistry systems involved in memory and learning. The study showed that even low-level microwave exposure altered choline uptake and muscarinic receptors in brain regions critical for cognitive function. These neurochemical changes occurred at power levels well below current safety standards.
