What does the human brain do when your asleep?

Answer 1

Not so well. In a way surprisingly similar to when you are drunk. I highly recommend Counting Sheep, By: Paul Martin for more on this subject. Reaction time is impaired. You are more temperamental. You may make reckless decisions more often than were you not tired. Basically nothing goods from being more tired. Learning is impaired, and a lack of sleep prevents learning from occurring.

AnswerActually, newer research (i.e. past 5-10 years) indicates that the degree to which fatigue affects your cognitive abilities is rather small. Sleep deprivation's biggest effect is on your mood, making you cranky and thus changing your appraisal of situations and your abilities. However, the brain is pretty determined to make you sleep more than you need (in contradication to older, poorly executed studies, Adults are healthiest getting about 6 hours of sleep a night, while the brain tries to force you into eight or more) so it is dangerous to do high-risk activities (i.e. driving) because you have to divert energy to fighting this urge to sleep. However, if you are tired and anxious because of getting 5-6 hours of sleep a night, try to stop worrying about it and you will be less tired. After reading these studies, I changed my sleeping patterns and have felt great!

Answer 2

No, unless a person has deceased, the human brain never stops working. Your brain is responsible for dreams, which is a prime example as to how well the brain still works even when asleep. If the brain was not working one could not dream, move, breathe, or even wake up from sleep. This holds true for every species of animal in which the brain is the main component of the central nervous system.
