この研究は、147 MHz、その低調波73.5 MHz、36.75 MHzのそれぞれの振幅変調電磁界（変調周波数16 Hzおよび76 Hz）への長期ばく露（30 - 35日、1日3時間）が、発達中のラットの脳内コリン作動系に影響を与えるか否かを調べた。その結果、ばく露群において、対照群と比較して、アセチルコリンエステラーゼ（AChE）活性の有意な低下が見られた；AChE活性の低下は、搬送周波数には依存しなかった；短期ばく露はAChE活性に有意な影響を与えなかった、と報告している。

To study the effect of amplitude modulated radiofrequency radiation on central cholinergic system in developing rat brain.
|チャンバの詳細||Plexiglas cages (32 x 10 x 9 cm³) were aerated by small circular holes.|
|ばく露装置の詳細||Four rats were kept in a cage, restrained with their long body axis parallel to the electric field.|
|Sham exposure||A sham exposure was conducted.|
|Additional information||One time exposure for up to 3 h was also tested.|
|SAR||0.14 W/kg||mean||-||-||0.1-0.14 W/kg|
|ばく露装置の詳細||160 µg of membrane protein from various groups of exposed and control rats were exposed in vitro in polyallomer tubes to their respective fields.|
A significant decrease in acetylcholinesterase activity was observed in exposed animals as compared to the control. Decrease in acetylcholinesterase activity was independent of carrier wave frequencies. A short-term irradiation did not have any significant effect on the enzyme activity of acetylcholinesterase.
