Plain English Summary
French researchers studied how GSM cell phone radiation affects brain activity by measuring auditory evoked potentials (electrical signals the brain produces when hearing sounds) in both healthy people and epileptic patients. They found that exposure to GSM radiofrequency radiation measurably altered brain wave patterns, reducing the amplitude of a key brain response called N100 and speeding up response times in healthy subjects. This demonstrates that cell phone radiation can directly influence how the brain processes information, even though the researchers couldn't determine if these changes affect actual brain function.
Why This Matters
This 2004 study provides compelling evidence that GSM cell phone radiation directly alters brain activity in measurable ways. The researchers used sophisticated machine learning techniques to detect changes in brain wave patterns that human analysis might miss, finding consistent effects in both healthy individuals and epileptic patients. What makes this research particularly significant is that it demonstrates objective, measurable changes in brain electrical activity during RF exposure, not just subjective reports. The fact that epileptic patients showed even greater amplitude reductions suggests some individuals may be more susceptible to RF effects. While the researchers cautiously noted they couldn't prove functional impairment, the reality is that any technology capable of altering brain electrical patterns deserves serious attention and further investigation.
Exposure Information
Specific exposure levels were not quantified in this study.
