When a dialing mobile phone was placed on the ear, the brain showed enlarged electrical reactivity to its radiation peaks, though whether this affects health remains unknown.

Plain English Summary

Summary written for general audiences

Researchers investigated whether third generation mobile phone radiation peaks produce event-related potentials in the brain. Thirty-one healthy females took part in a single-blind, cross-over design where a 15 minute mobile phone exposure was compared to two 15 minute sham phone conditions. When the phone was placed at the ear, an enlarged cortical reactivity was found in the frontal and central cortical regions, but not when it was placed at the heart.

Why This Matters

Each participant was measured on two separate days, with phone placement varied between the ear and heart. EEG activity and radiofrequency radiation were recorded jointly during the sessions. Epochs of 1200ms, starting 200ms before and lasting until 1000ms after the onset of a radiation peak, were extracted from the exposure condition. The main hypothesis concerned an increase of the area in the 240-500ms post-stimulus interval during ear-placement exposure, which was confirmed by multilevel regression analyses. Post-hoc analyses also found a second significantly increased area between 500-1000ms post-stimulus for almost every EEG location measured. The researchers concluded that the brain detects the radiation unconsciously, but left the question of any health consequence to future longitudinal experiments.

It was concluded that, when a dialing mobile phone is placed on the ear, its radiation, although unconsciously, is electrically detected by the brain. The question of whether or not this cortical reactivity results in a negative health outcome has to be answered in future longitudinal experiments.

Quick Questions About This Study

Thirty-one healthy females participated in the study.
The frontal and central cortical regions showed enlarged cortical reactivity only during mobile phone exposure with ear-placement.
The researchers did not conclude that the cortical reactivity is harmful, stating that the question of whether it results in a negative health outcome has to be answered in future longitudinal experiments.
A 15 minute mobile phone exposure was compared to two 15 minute sham phone conditions, one preceding and one following the exposure condition.
Researchers concluded that the radiation is detected by the brain although unconsciously.
