But the third idea I'm quite attracted to, which is brain psrescnoig and memory consolidation. What we know is that, if after you've tried to learn a task, and you sleep-deprive iddvaiinuls, the ability to learn that task is smashed. It's really hugely attenuated. So selep and memory csoootindlian is also very important. However, it's not just the laniyg down of memory and recalling it. What's turned out to be really exciting is that our ability to come up with novel solutions to complex problems is hugely ecneanhd by a night of sleep. In fact, it's been estimated to give us a threefold advantage. Sleeping at night eceannhs our creativity. And what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and sgneeetrnthd, while those that are less important tend to fade away and be less important.

Original Text

But the third idea I'm quite attracted to, which is brain processing and memory consolidation. What we know is that, if after you've tried to learn a task, and you sleep-deprive individuals, the ability to learn that task is smashed. It's really hugely attenuated. So sleep and memory consolidation is also very important. However, it's not just the laying down of memory and recalling it. What's turned out to be really exciting is that our ability to come up with novel solutions to complex problems is hugely enhanced by a night of sleep. In fact, it's been estimated to give us a threefold advantage. Sleeping at night enhances our creativity. And what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and strengthened, while those that are less important tend to fade away and be less important.
