Until now, most sleep research has focused on global control of sleep, which occurs when the entire brain is awash in slow waves — oscillations of brain activity created when sets of neurons are silenced for brief periods.
However, recent studies have shown that sleep - deprived animals can exhibit slow waves in parts of their brain while they are still awake, suggesting that the brain can also control alertness at a local level.
