Interesting theory, but how are you going show that this is right if there are no conscous affects? Oohashi measured brain waves to do this. http://jn.physiology.org/cgi/content/full/83/6/3548 And if you believe that.... Why don't you dispute it then? Been there, done that many times, Stephen should be well-aware of the details, He's trolling, as usual. You asked how one could show the affects of high frequencies. Oohashi did that. Since you know he did so, that makes you the troll. And you didn't dispute so much as reject the findings. Stephen Yes, and Arny has to deal with this, too: http://illumin.usc.edu/article.php?articleID=45&page=3 If the brain can localize based upon differential delays as small as 10 us, this implies some discrimination of higher frequencies, not by the mechanism that senses tone, but by something else. Mathematically, as I am sure you are aware, this is because there is no such thing as a 20 kHz sine wave that starts up from nothing. The Fourier series of the startup of a perfect tone includes higher order coefficients that die away as t -- infinity. The only mathematical artifacts that are available to discriminate a 10 us difference are these transient Fourier coefficients. We can't hear the tones, but somehow, these coefficients get into the brain with the recognition by neural circuitry that they represent ultrasonics. |
