<div><br><br><div class="gmail_quote">On Tue, Oct 9, 2012 at 4:52 PM, Sai <span dir="ltr"><<a href="mailto:noisebridge@saizai.com" target="_blank">noisebridge@saizai.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Can you provide any reason whatsoever why we should believe that the<br>
ear canal is even sensitive to degree of light, let alone color?<br>
<br>
Binaural beats are 100% irrelevant to this, as is light stimulation of<br>
the eyes (which, shockingly, *do* contain light receptors).<br>
<br>
You're proposing to flash light into someone's *ear*, and claiming<br>
that this will somehow affect their brain. That's simply not possible<br>
without there being some kind of light receptors there, and there are<br>
none.<br>
<br>
Also, mind that with EEG you're going to have very high sensitivity to<br>
placebo effect. Any trial that's not fully blinded will not be worth<br>
looking at.<br>
