The switch in the brain that sends us off to sleep has been identified by researchers at Oxford University's Centre for Neural Circuits and Behaviour in a study in fruit flies. The switch works by regulating the activity of a handful of sleep-promoting nerve cells, or neurons, in the brain. The neurons fire when we're tired and need sleep, and dampen down when we're fully rested.
