Plain English Summary
French researchers exposed rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) and measured changes in GABA, a crucial brain chemical that helps regulate nerve activity. They found that RF exposure reduced GABA levels in the cerebellum, the brain region responsible for movement and coordination. This suggests that cell phone radiation may disrupt normal brain chemistry at the cellular level.
Why This Matters
This study provides important evidence that radiofrequency radiation can alter brain chemistry in ways that could affect neurological function. GABA is your brain's primary inhibitory neurotransmitter - it essentially acts as the brake pedal for nerve activity, helping maintain proper brain function and preventing overstimulation. The fact that 900 MHz radiation reduced GABA levels in the cerebellum is particularly concerning because this brain region controls motor coordination and balance. The researchers tested exposure levels of 4 W/kg and 32 W/kg SAR - for context, current safety limits allow up to 2 W/kg for cell phones, meaning the lower exposure tested was only twice the legal limit. What makes this research especially valuable is that it demonstrates biological effects at the cellular level using sophisticated imaging techniques, providing a clear mechanism for how RF radiation might impact brain function beyond simple heating effects.

Overall, it appears that high energetic radiofrequency exposure induces a diminution in cellular GABA content in the cerebellum.
