Late Risers Rule! HEHEHE!<\/h1>\n

Then subjects spent two nights in a sleep lab, where they again followed their preferred sleep patterns and underwent cognitive testing twice daily while in a functional MRI<\/a> scanner.
\nAn hour and a half after waking, early birds<\/a> and night owls<\/a> were equally alert and showed no difference in attention-related brain<\/a> activity. But after being awake for 10 and a half hours<\/a>, night owls had grown more alert, performing better on a reaction-time<\/a> task requiring sustained attention and showing increased activity in brain areas linked to attention. More important, these regions included the suprachiasmatic area, which is home to the body\u2019s circadian clock<\/a>. This area sends signals to boost alertness<\/a> as the pressure to sleep mounts. Unlike night owls, early risers<\/a> didn\u2019t get this late-day lift. Peigneux says faster activation of sleep pressure appears to prevent early birds from fully benefiting from the circadian signal, as evening types do.
