I'm no brain surgeon :) but i am looking for information of
BrainWave activity and how different audio levels affects the
I am looking mostly for papers or something similar that deals with
say "Theta Brain Wave is triggered by a 5-7HZ frequency" etc...
I see now there are alot of people producing little gadgets that put
out these audio frequencies that the brain responses to.
There was a person (Andew Neher i believe) in the 40's in geramny
that used to put a certain audio frequency out when hitler was
giving his speech's.
Is it basically all based around sub audio frequencies?
Any help or pointer would be great!
