The human brain takes a rest of its own when you go to sleep, according to new research.
A study paired EEG (electroencephalogram) readings with data collected by electrodes measuring electrical activity inside the brain while patients slept.
The results showed that neurons within the brain sometimes take short breaks during sleep, and that these rest periods allow us to remain asleep even though the brain registers noise or some other disturbance.
In other words, neurons rest so people can rest, too!
