Actually, the USSR did research into electromagnetic fields in the 60s and 70s-- EMFs like the ones emitted by your computer, your television, and your cell phone.
“Over the past years, US researchers have confirmed the possibility of affecting functions of the nervous system by weak electromagnetic fields (EMFs), as it was previously said by Soviet researchers. EMFs may cause acoustic hallucination (’radiosound’) and reduce the sensitivity of humans and animals to some other stimuli, to change the activity of the brain (especially the hypothalamus and the cortex), to break the processes of formation processing and information storage in the brain. These nonspecific changes in the central nervous system can serve as a basis for studying the possibilities of the direct influence of EMFs on specific functions of CNS,” read an article in Nauka (Science) magazine in 1982.
So it's not only about the message being delivered, it's also about the devices we use on a daily basis to communicate.. and the effects they have on our memories and ability to make new memories. This was in the 60s and 70s... any developments made since then are classified.
