While it seems easy, recognizing those faces is a cognitively complex task. Your brain must identify the object you're seeing as a face, regardless of the size or angle; interpret the expression encoded by the particular arrangement of eyes and mouth; and access the memory part of the brain to determine if the face is familiar. By combining two of the most important tools in neuroscience--brain imaging and electrical recordings from single brain cells--scientists are poised to finally understand how the brain performs these complex computations.</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/read_article.aspx?id=19016">Shape recognition is one of the biggest unsolved questions in visual biology</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;"> </td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/F118D9F4-529C-452C-8CCE-D0EA4C07E11B/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>
