<STRONG>T</STRONG>he world is a dangerous place. Every day we face a variety of threats, from careening automobiles to stock market downturns. Arguably, one of the most important functions of the brain and nervous system is to evaluate threats in the environment and then coordinate appropriate behavioral responses to avoid or mitigate harm.</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.sciencemag.org/cgi/content/full/317/5841/1043">
Imminent threats and remote threats produce different behavioral responses, and many animal studies suggest that the brain systems that organize defensive behaviors differ accordingly</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.sciencemag.org/cgi/content/full/317/5841/1043">different neural circuits in the human brain are engaged by distal and proximal threats, and that activation of these brain areas correlates with the subjective experience of fear elicited by the threat (<A href="#ref2">2</A>). By pinpointing these specific brain circuits, we may gain a better understanding of the neural mechanisms underlying pathological fear, such as chronic anxiety and panic disorders.</blockquote><div style="border-bottom: solid 1px #dcdcdc; white-space: nowrap; margin-bottom: 8px; background-color: #eeeeee ;background-image: url(http://www.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.sciencemag.org/cgi/content/full/317/5841/1043/F1" href="http://www.sciencemag.org/cgi/content/full/317/5841/1043/F1" style="font-size: 11px;">www.sciencemag.org</a></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciencemag.org/cgi/content/full/317/5841/1043/F1"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/www.sciencemag.org/img/42A1FFE8-15A0-4355-AF63-FF9EA53BC686" alt="" /></div></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/D6ABEEA6-C645-49E9-A21E-ED2B81E90E48/blog/" title="blog or email this clip"><img src="http://content6.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>
