User blog comment:GodzillaMaster/Theory on the Reapers/@comment-743796-20110826141616

Maybe the materials that make up the Reapers' composition is designed to amplify a signal or a type of radiation (infrared or x-ray) that would clash with organics' minds for a period of time, until the victim's will is broken down and responds only to the signals being sent. That could explain why indoctrinated servants were taken in by other protheans and how those host were caught, due to the lingering signal in their heads. My guess is that if this theory proves correct, that those exposed to eezo would become even more susceptible to indoctrination. Of course, it would still take a very long period of time before such an effect would take place, otherwise people would keep their distances.
