That’s right. My eyes were making a horrid grating noise whenever they moved—a noise that only I could hear. I had the great fortune of meeting one of the few people who could understand my symptoms: <A href="http://gumc.georgetown.edu/departments/physiology/rauschecker.html">Josef Rauschecker</A>, a professor of physiology and biophysics at Georgetown University , and one of the world’s authorities on the auditory cortex</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciam.com/article.cfm?id=noisy-eyeballs-regulating-information-brain">He suggested that my noisy eyeballs were triggered by serotonin, a neurotransmitter in the brain</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciam.com/article.cfm?id=noisy-eyeballs-regulating-information-brain">Rauschecker explained that his recent brain scans of people suffering from <A href="http://www.sciam.com/podcast/episode.cfm?id=4710B480-AC66-0E69-B8FA4BFAA038851E">tinnitus</A>, a constant ringing in the ears, show that a particular part of their brain—the nucleus accumbens—is smaller than normal. This nugget of nerve cells helps to regulate the flow of sensory information to the cerebral cortex via another major relay center, the thalamus</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/21BE9EFC-F64B-4EF1-8601-B13EF39371AF/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
