You Can Be Asleep Even If Awake!

A lot of studies have already been conducted to explore the human mind's conscious and subconscious levels while a person is sleeping and while he is awake after having little to no sleep at all for a long time.

Having a system closest to humans when it comes to the brain, rats were used to perform the studies. Based on the trials done on these rats, even though the brain is fully awake and can function in general, there are certain abilities that become limited or completely shut down every now and then. This is due to the fact that the neurons transferring information throughout the body cannot work well when a person is deprived of sleep and alternately  turns on and off.
