Even wee little bugs need a good snooze

I heard recently that it's better to think of sleep as a state of repair, not rest. It makes sense that the brain would have to reorder itself somewhat to account for new information. But even tiny little bugs need to do this, or else they get cranky.

And just as in people, interrupting insects’ sleep can harm brain performance and change behaviour, Klein and others have found. Honeybees perform intricate dances to tell each other where to find flowers. But after being kept awake with an evil lab contraption called the “insominator,” honeybees’ dances grew sloppy, Klein and colleagues reported in 2010 in the Proceedings of the National Academy of Sciences.
