Support is growing for a theory that sleep evolved so that connections between neurons（神经元） in the brain can be weakened overnight, making room for fresh memories to from the next day. 73 Now we have the most direct evidence yet that he is right. 74 The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping. If Tononi’s theory is right, it would explain why, when we miss a night’s sleep, we find it harder the next day to concentrate and learn new information -- our brains may have smaller room for new experiences. Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. 75 “You keep what matters,” Tononi says. A. We should also try to sleep well the night before. B. It’s as if the brain is preserving its most important memories. C. Similarly, when people go for a few days without sleeping, they get si
