Researchers exposed genetically modified Alzheimer's mice to 1950 MHz radiofrequency radiation (similar to cell phone frequencies) for 3 months to see if it worsened memory problems.

Researchers exposed rat brain tissue to pulsed microwave radiation at various power levels (0.5 to 15.0 mW/cm²) and frequencies (16 and 32 Hz) to see if it affected calcium movement out of cells. They found no significant differences in calcium efflux between irradiated and control samples, suggesting these specific microwave conditions did not disrupt this cellular process.

Scientists exposed conscious rats to low-power pulsed microwaves at 1 and 15 mW/cm² and measured blood flow changes in 20 different brain regions. Both exposure levels increased blood flow by 10-144% in 16 brain areas, with the largest increases in the pineal gland, hypothalamus, and temporal cortex. This demonstrates that microwave radiation at power levels similar to everyday devices can trigger significant metabolic changes in brain tissue.

Researchers used Raman spectroscopy to examine how microwave radiation affects sphingomyelin lipids extracted from cow brain cell membranes. The study found that these membrane components, which undergo natural phase transitions at body temperature (30-40°C), showed changes in fluidity when exposed to microwaves. This matters because cell membrane integrity is crucial for proper brain function.
