Sleep is a brain-repair mechanism, new study proves

Scientists Lior Appelbaum and David Zada in Israel publish new proof that sleep serves to help our brains repair damage. Their study, published in the journal Nature, used genetically engineering transparent zebrafish with colorful chemical tags attached to chromosomes in their neurons, and found that chromosomes constantly change shape to repair DNA damage, but move twice as much during sleep as when awake. “I think this is one of the key reasons we need to sleep,” said Lior Appelbaum from B...

Sleep Helps To Repair Damaged DNA In Neurons, Scientists Find

An anonymous reader quotes a report from The Guardian: Scientists have discovered that broken DNA builds up in brain cells in the daytime and repair work reverses the damage only during sleep. For an act so universal, sleep has enormous benefits. Found in organisms from flies to worms and jellyfish, it restores the body and helps learning and memory. But despite extensive research, the purpose of sleep is still mysterious. Lior Appelbaum from Bar-Ilan University and his student, David Zada, reas...
