Plain English Summary
French researchers exposed lab-grown brain cell networks to cell phone radiation (GSM-1800) for 3 minutes and measured their electrical activity in real time. They found that the radiation caused a 30% decrease in the brain cells' firing rate and bursting patterns - essentially making the neurons less active. The effect was reversible, meaning the cells returned to normal activity after exposure ended.
Why This Matters
This study provides direct evidence that cell phone radiation can alter brain cell activity at the cellular level. The researchers used a SAR level of 3.2 W/kg, which is higher than typical phone use (around 1-2 W/kg) but within the range that occurs during heavy use or poor signal conditions. What makes this research particularly significant is that it demonstrates immediate, measurable changes in how neurons communicate - the fundamental process underlying all brain function. The fact that the effect was reversible suggests the brain cells weren't permanently damaged, but it raises important questions about what happens with repeated or prolonged exposure. This adds to a growing body of research showing that RF radiation can influence nervous system function, contradicting industry claims that non-thermal effects don't exist.
