View Original AbstractCell phone frequency EMF exposure immediately altered brain wave patterns in healthy mice, showing real-time neurological effects during exposure.
Plain English Summary
Researchers directly measured brain electrical activity in mice while exposing them to cell phone frequency electromagnetic fields. They found that healthy mice showed clear changes in brain wave patterns, with cortical activity shifting to lower frequencies and hippocampal activity increasing in higher frequencies. These real-time brain changes during EMF exposure provide direct evidence that radiofrequency radiation can alter normal brain function.
Why This Matters
This study stands out because it captures brain activity changes in real time during EMF exposure, rather than looking for effects after the fact. The researchers used a clever methodology with gel electrodes to avoid interference from the electromagnetic field itself, giving us a clear window into what happens to brain electrical activity during cell phone frequency exposure. What makes this particularly significant is that the effects were immediate and measurable in healthy animals, suggesting our brains are actively responding to these fields as they encounter them. The fact that different brain regions showed opposite effects (cortex slowing down, hippocampus speeding up) indicates EMF exposure doesn't just create general interference, but specific disruptions to normal brain rhythms. Put simply, this research demonstrates that the electromagnetic fields from our phones are doing something to our brains while we're using them, not just potentially causing problems down the road.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
A direct registration of brain cortical and hippocampal activity during a high-frequency electromagnetic field (HF EMF) exposure was performed.
All experimental procedures were done under urethane anaesthesia (20%, 2 g/kg i.p.) in Lurcher mutan...
ECoG evaluation showed a distinct shift to lower frequency components but clear effect has been obse...
These findings support the idea about possible influencing the central nervous system by HF EMF exposure and support also some recent results about possible health risks resulting from cellular phones use.
