Cell phone radiation at typical exposure levels showed no immediate effects on the brain's automatic sound processing in healthy adults.

Plain English Summary

Summary written for general audiences

Researchers tested whether cell phone radiation affects the brain's ability to automatically detect changes in sounds by measuring brain waves in 17 healthy adults while a GSM phone was placed next to their ear. They found no differences in brain responses whether the phone was on or off, suggesting that acute exposure to cell phone radiation doesn't impair this basic auditory processing function. This study adds to research examining how electromagnetic fields might affect brain function during everyday phone use.

Study Details

The aim of this study is to investigate Preattentive auditory information processing under exposure to the 902 MHz GSM mobile phone electromagnetic field: A mismatch negativity (MMN) study.

In this study, MMN responses to duration, intensity, frequency, and gap changes were recorded in hea...

An MMN was elicited by all deviant types, while its amplitude and latency showed no significant diff...

In the present study, we found no conclusive evidence that acute exposure to GSM mobile phone EMF affects cortical auditory change detection processing reflected by the MMN.
