basically all living tissue absorbs RF because it's full of water. This also affects brain electrical activity: https://www.ncbi.nlm.nih.gov/books/NBK208983/

  First: those effects are of high power, nearby fields. The EM contamination in our environment is very low power, mostly lower frequencies, and evenly distributed. It's hard to imagine it affecting any brain signal, since even the lowest present frequencies are three orders of magnitude faster than a neuron's polarity change. I don't know that water absorbs normal radio frequencies. Above 1GHz or so, it starts to absorb, but the effect is heating, nothing else. Having a mobile phone next to your head increases the temperature in nearby brain tissue a little bit, so it's hard to image that the low power frequencies can do anything else but increase the temperature very, very lightly, something which the body can deal with effectively. I don't see it.
