Plain English Summary
Finnish researchers tested how cell phone radiation affects working memory by having participants complete memory tasks with and without exposure to GSM phone signals (902MHz). They found that phone radiation actually sped up response times when people had to remember three items at once, but had no effect on easier memory tasks. This suggests that cell phone radiation can measurably alter brain function and cognitive performance.
Why This Matters
This early study from 2000 reveals something fascinating: EMF exposure doesn't just potentially harm cognitive function, it can actually enhance certain aspects of brain performance under specific conditions. The researchers found that GSM radiation at 902MHz improved response times during challenging working memory tasks. While this might sound positive, it's actually concerning evidence that cell phone radiation is actively interfering with normal brain function. The fact that EMF exposure can speed up cognitive processing suggests it's altering neural activity in ways we don't fully understand. What this means for you is that your brain is responding to cell phone radiation whether you realize it or not. The long-term consequences of this neural stimulation remain unknown, but the evidence shows your brain isn't immune to EMF effects.
Exposure Information
Specific exposure levels were not quantified in this study. The study examined exposure from: 902MHz, 217Hz
Study Details
The influence of pulsed radiofrequency (RF) electromagnetic fields of digital GSM mobile phones on working memory in healthy subjects were studied.
Memory load was varied from 0 to 3 items in an n-back task. Each subject was tested twice within a s...
The RF field speeded up response times when the memory load was three items but no effects of RF wer...
The results suggest that RF fields have a measurable effect on human cognitive performance and encourage further studies on the interactions of RF fields with brain function.
