Plain English Summary
Finnish researchers exposed 72 men to 902 MHz mobile phone radiation while they performed memory tasks, measuring brain wave patterns through EEG. The study found only modest, inconsistent effects on brain oscillations in the alpha frequency range, with no impact on actual memory performance. The researchers concluded that any brain wave changes from phone radiation appear to be subtle, variable, and difficult to replicate consistently.
Study Details
The aim of the current double‐blind studies was to partially replicate the studies by Krause et al. [2000a, b, 2004] and to further investigate the possible effects of electromagnetic fields (EMF) emitted by mobile phones (MP) on the event‐related desynchronisation/synchronisation (ERD/ERS) EEG (electroencephalogram) responses during cognitive processing.
Two groups, both consisting of 36 male participants, were recruited. One group performed an auditory...
In line with our previous studies, we observed that the exposure to EMF had modest effects on brain ...
We conclude that the effects of EMF on brain oscillatory responses may be subtle, variable and difficult to replicate for unknown reasons.
