This rigorous study found no measurable brain function changes from 30 minutes of mobile phone radiation at typical exposure levels.

Plain English Summary

Summary written for general audiences

Researchers exposed 120 people to mobile phone radiation for 30 minutes while measuring their brain activity and reaction times during cognitive tasks. They found no significant changes in brain function, reaction speed, or electrical brain patterns compared to fake exposure sessions. This contradicts some earlier studies that suggested cell phones might affect how quickly the brain processes information.

Study Details

The current investigation (n = 120) aimed to test recent findings in this area, namely that N100 amplitude and latency would decrease, and that P300 latency and reaction time (RT) would increase under active relative to sham exposure during an auditory task.

Visual measures were also explored. A double blind, counterbalanced, crossover design was employed w...

There was no significant difference between exposure conditions for any auditory or visual event rel...

As previous positive findings were not replicated, it was concluded that there is currently no evidence that acute MP exposure affects these indices of brain activity.
