Plain English Summary
Researchers exposed mice to 900 MHz electromagnetic radiation (the same frequency used by cell phones) and directly measured brain activity in two key regions: the cortex and hippocampus. They found that this radiation altered normal brain wave patterns, shifting cortical activity to lower frequencies while increasing higher frequencies in the hippocampus. These changes occurred even though the mice received lower radiation doses than humans typically get when using cell phones.
Why This Matters
This study provides direct neurological evidence that cell phone radiation can alter brain function in real time. What makes this research particularly significant is that the researchers measured actual brain activity during exposure, not just cellular changes examined after the fact. The science demonstrates that 900 MHz radiation can disrupt normal neural oscillations in both the cortex (involved in thinking and consciousness) and hippocampus (critical for memory formation). The reality is that these mice experienced brain wave changes at exposure levels lower than what your brain receives during a typical phone call. While we can't directly extrapolate mouse studies to humans, this adds to the growing body of evidence showing that radiofrequency radiation affects nervous system function at levels regulators currently consider safe.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 900 MHz HF-EMF Cellular Phones

Despite our experimental paradigm (i.e. whole-body HF EMF exposure characterized by lower amount of absorbed energy in comparison with human brain during cellular phone use), presented results suggest that some neuronal populations (cortical and subcortical) react on this type of radiation.
