Plain English Summary
Greek researchers studied how Wi-Fi signals affect brain activity in 30 people performing memory and attention tasks. They found that Wi-Fi exposure specifically reduced brain activity (measured by P300 brain waves) in men but not women during tasks requiring mental focus and working memory. This suggests Wi-Fi may impair cognitive function differently based on gender, with men showing decreased attention and memory processing when exposed to wireless signals.
Why This Matters
This study adds important evidence to the growing body of research showing Wi-Fi can alter brain function in measurable ways. The gender-specific effects are particularly significant - men showed reduced neural activity associated with attention and working memory only when Wi-Fi was present, while women appeared unaffected. This finding aligns with other research suggesting biological differences in EMF sensitivity between sexes. What makes this research especially relevant is that it used real-world Wi-Fi exposure, not just laboratory conditions. The cognitive processes studied - attention and working memory - are fundamental to daily tasks like concentration at work, learning, and decision-making. While the study doesn't specify exact exposure levels, typical Wi-Fi operates at power levels we encounter constantly in homes, offices, and schools.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
The P300 component of event-related potentials (ERPs) is believed to index attention and working memory (WM) operation of the brain. The present study focused on the possible gender-related effects of Wi-Fi (Wireless Fidelity) electromagnetic fields (EMF) on these processes.
Fifteen male and fifteen female subjects, matched for age and education level, were investigated whi...
P300 amplitude values at 18 electrodes were found to be significantly lower in the response inhibiti...
In conclusion, the present findings suggest that Wi-Fi exposure may exert gender-related alterations on neural activity associated with the amount of attentional resources engaged during a linguistic test adjusted to induce WM.
