Question: Is it possible for one part of our brain to sleep?If it is what would happen to the rest of the brain that is awake?

Good question! Our brain doesn’t actually shut down when we sleep, its busy processing information we’ve taken in that day. Some parts are more active than others when we sleep because some areas are more associated with dreaming. But interestingly, dolphins can sleep with half of their brain and use the other half to swim!
