Plain English Summary
Finnish researchers used brain imaging to study how cell phones affect blood flow in the brain while 12 men performed memory tasks. They found that an active mobile phone decreased blood flow directly beneath the antenna in the temporal lobe while increasing it in the frontal brain region. This provides the first direct evidence that cell phone radiation can measurably alter brain physiology in humans.
Why This Matters
This groundbreaking study represents a crucial milestone in EMF research because it provides objective, measurable evidence that cell phone radiation affects brain function in real-time. Using positron emission tomography (PET) imaging, the researchers demonstrated that the electromagnetic fields from a commercial mobile phone cause detectable changes in regional cerebral blood flow patterns. What makes this particularly significant is that blood flow changes indicate altered neuronal activity, suggesting that your brain responds physiologically to cell phone radiation even during normal use. The fact that these changes occurred in specific brain regions corresponding to antenna placement adds biological plausibility to concerns about localized EMF effects. While the study doesn't establish harm, it definitively shows that cell phone radiation isn't biologically inert as industry often claims.

Our results provide the first evidence, suggesting that the EMF emitted by a commercial mobile phone affects rCBF in humans. These results are consistent with the postulation that EMF induces changes in neuronal activity.
