Once sleep was thinking as a passive state, however, now it is understood as a dynamic process, and the brains are active during sleep. Sleep is a complicated physiological phenomenon that scientists still not able to understand fully.

Brains state of activity during sleep and wakefulness result from different activating and inhibiting forces that were causing within the brain. Neurotransmitters are chemicals involved in nerve signaling, which controls whether one is asleep or awake by acting like the neurons (nerve cells) located in different parts of the brain. Neurons located in the brainstem induce sleep by inhibiting other parts of the brain that keeps one awake.
