Why the lack of sleep doesn't hurt some people as much as it does others.

diseases, and of course weakened cognitive functioning. But a bad night’s sleep 
doesn’t hurt everyone equally. Unlike me, some people can think clearly no 
matter what. A study published June 24th in <EM>The Journal of Neuroscience</EM> 
helps explain why. <BR><BR>Scientists looked for a genetic marker called 
<EM>Period 3</EM> known to predict the effects of sleep deprivation. People with 
short versions of the gene do okay when they lose sleep. But the longer gene 
leads to suffering with lack of sleep. <BR><BR></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.scientificamerican.com/podcast/episode.cfm?id=genetic-protection-against-sleep-de-09-06-29">Researchers tested attention and cognition before and after both good and bad 
nights’ sleeps. Those with the long <EM>Period 3</EM> had poor function in the 
part of the brain that would usually spring to life. Even after a decent night, 
the long-gene people had reduced brain activity towards the end of the day. But 
folks with the short gene did better, and their brains even pulled in extra 
assistance from surrounding brain areas.</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/6777DC05-DE04-4C6C-BE98-20A367AED410/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>
