hinge on the amount of a neurochemical called GABA, which acts to inhibit brain activity
circadian clock controls the daily cycle of sleep and wakefulness by inhibiting different parts of the brain by releasing GABA
if the hippocampus – the part of the brain where memories are stored – is overly inhibited, then the circuits responsible for memory storage don’t function properly
performed terribly on a simple learning task, even though they’re getting loads of sleep
circadian system really is necessary for something that is deeply important: learning
