Scientists Now Know How Sleep Cleans Toxins From the Brain
Laura Lewis and her team of researchers have been putting in late nights in their Boston University lab. Lewis ran tests until around three in the morning, then ended up sleeping in the next day. It was like she had jet lag, she says, without changing time zones. It\u2019s not that Lewis doesn\u2019t appreciate the merits of a good night\u2019s sleep. She does. But when you\u2019re trying to map what\u2019s happening in a slumbering human\u2019s brain, you end up making some sacrifices.
