Another of those stories that folks gravitate to. I was about to ClipMark it earlier, but did a search in here and saw that I was not Daniel Boone and others had walked down this path before...

"Have I been here before?"  In today's fast-moving world of look-alike hotel rooms and comparable corridors, it can take a bit of thinking to answer this simple question. University of Bristol neuroscientists working with colleagues at the Massachusetts Institute of Technology (MIT) report in the June 7 early online edition of <I>Science</I> that they have identified a neuronal mechanism that our brains may use to rapidly distinguish similar, yet distinct places</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://physorg.com/news100444183.html"> 
The work could lead to treatments for memory-related disorders, as well as for the confusion and disorientation that plague elderly individuals who have trouble distinguishing between separate but similar places and experiences.</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://physorg.com/news100444183.html">We constantly make split-second decisions about how best to behave at a given place and time.  To achieve this, our nervous system must employ highly efficient ways of rapidly recognising and learning important changes in our environment.</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/264F2100-E323-49D4-B240-320A670B5E56/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>
