I’ve posted before about this, but it may have flown below the radar. Here is a fully detailed and peer-reviewed article that describes how VLF energy can activate human nerve cells. I took it a bit further down the road by suggesting the mechanisms whereby oscillating RF fields can be created hundreds of kilometres away from the source of VLF energy, and also by assuming that nerve cells in the auditory system can be activated in the way that the authors suggest. Here is the article: http://kyttariki.biol.uoa.gr/mobile_phones/article-2002.pdf
Let me know if you’d like me to explain any part of the article in plain English (after all, I am a teacher!).
