この研究は、ロング・ターム・エボリューションLTE)デバイスから発せられる無線周波RF電磁界が脳の電気的活動の機能的接続を変調し得るかどうかを、脳電図(EEG)を用いて調査した。被験者二重ブラインド法で実ばく露と偽ばく露の2つのセッション(各30分間)に参加した。実験を通じて32チャネルでEEG信号を取得し、同期尤度法を適用して、異なる周波数帯域および異なるEEG記録期間での脳全体の神経同期を定量化した。その結果、短期的なLTEばく露は、脳全体を通じたEEG活性化の同期パターンが変調されることが示された。

研究目的(著者による)

The effects of an acute exposure of human probands to a 2573 MHz electromagnetic field on the neural synchronization in the brain should be investigated.

詳細情報

Ten healthy subjects participated at two sessions (exposure and sham exposure), respectively, with each session lasting for 50 minutes (10 min rest, 30 minutes exposure or sham exposure, 10 minutes rest) and being conducted with an interval of one week.

研究の主なアウトカム(著者による)

Several statistically significant synchronization events were found in different frequency bands of exposed probands compared to sham exposure during and after exposure. The main areas of synchronization were located in the left and middle prefrontal areas and the right temporal areas.
The authors conclude that an acute exposure of human probands to a 2573 MHz electromagnetic field can modulate the brain activity, even in brain regions remote from the source of exposure.
