These images, generated from a living human brain, show a reconstruction of the entire brain (above) and a subset of fibers (below). The red fibers in the middle and lower left of both images are part of the corpus callosum, which connects the two halves of the brain. </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://www.technologyreview.com/biomedicine/21462/"><div align="center"><img src="http://content8.clipmarks.com/blog_cache/www.technologyreview.com/img/A1A54D9A-B66F-4AF4-B9D9-EF7ADD7AFE04" alt="" /></div></blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content9.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://www.technologyreview.com/biomedicine/21462/page2/" href="http://www.technologyreview.com/biomedicine/21462/page2/" style="font-size: 11px;">www.technologyreview.com</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.technologyreview.com/biomedicine/21462/page2/"><div align="center"><img src="http://content6.clipmarks.com/blog_cache/www.technologyreview.com/img/A980077F-E52E-407D-B643-5856CE0C91B7" alt="" /></div></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.technologyreview.com/biomedicine/21462/page2/"><div align="center"><img src="http://content7.clipmarks.com/blog_cache/www.technologyreview.com/img/54757505-428E-41D8-80AB-F521A08A09C8" alt="" /></div></blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content8.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://www.technologyreview.com/biomedicine/21462/page3/" href="http://www.technologyreview.com/biomedicine/21462/page3/" style="font-size: 11px;">www.technologyreview.com</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.technologyreview.com/biomedicine/21462/page3/"><P> The result is a detailed diagram like that of the brain stem shown here.</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://www.technologyreview.com/biomedicine/21462/page3/"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/www.technologyreview.com/img/87852BA9-3561-4660-84F3-D662FB8871B2" alt="" /></div></blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://clipmarks.com/images/source-bg.gif); background-repeat: repeat-x; height: 24px; line-height: 24px; vertical-align: middle; padding-bottom: 4px; color: #666666; font-size: 10px;" ><a href="http://clipmarks.com/clip-to-blog/" title="see clips that are hot right now"><img src="http://content6.clipmarks.com/images/clip-icon.gif" alt="" width="19" height="19" border="0" style="vertical-align: middle; margin: 0px 4px; display: inline; border: none; float:none;" /></a>clipped from <a title="http://www.technologyreview.com/biomedicine/21462/page4/" href="http://www.technologyreview.com/biomedicine/21462/page4/" style="font-size: 11px;">www.technologyreview.com</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.technologyreview.com/biomedicine/21462/page4/">To study specific circuits in the brain, scientists can isolate a subset of fibers.
