By using a brain imaging technique that allows them to examine the links between the right temporal and frontal lobes, the scientists compared the neural connectivity of 10 tone-deaf subjects against 10 control participants. They found that, in the tone-deaf subjects, there was less connectivity of the <I>arcuate fasciculus</I> (AF), a white matter tract of fiber that serves as a "highway" between the temporal and front brain regions, and is known to be involved in linking language, music and vocal production.</P></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://wellness.blogs.time.com/2009/08/19/what-causes-tone-deafness/">this stretch of fiber was both smaller and less dense in people who are tone-deaf, and that one branch of the neural pathway was in fact undetectable on the scans.</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://wellness.blogs.time.com/2009/08/19/what-causes-tone-deafness/">may have similarities to other speech disorders in which there is also an interrupted link between what people hear and what they are able to produce.</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/D35FB997-F662-4C9B-BB61-589ED0FA1062/blog/" title="blog or email this clip"><img src="http://content7.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>
