Neurotransmitters in the brain are in charge of whether someone is asleep or awake. When the brain begins to produce neurotransmitters like melatonin, someone will begin to feel sleepy.
Frontal lobes are not very active during sleep; that is where the inhibition function lies. This is why (in your dreams) you do not make wise decisions.
Non-rapid eye movement (NREM) sleep-- A type of sleep that differs from rapid eye movement (REM) sleep. The four stages of NREM sleep account for 75-80% of total sleeping time.

REM (Rapid Eye Movement) sleep is active sleep.
R.E.M. Or rapid eye movement is a sign of deep sleep.
The brain's mechanisms for controlling sleep and arousal interact through a complex network of neurotransmitters and brain regions. The sleep-wake cycle is regulated by the interaction between the brainstem, hypothalamus, and other areas of the brain. The neurotransmitters involved in this process include serotonin, dopamine, and norepinephrine. These neurotransmitters help to promote wakefulness or induce sleep by influencing the activity of different brain regions. Additionally, the circadian rhythm, which is controlled by the suprachiasmatic nucleus in the hypothalamus, plays a key role in regulating the timing of sleep and wakefulness. Overall, the interaction between these various brain mechanisms helps to maintain a balance between sleep and arousal throughout the day.
The deepest stage of sleep is REM or Rapid Eye Movement.
No. Rapid Movement Sleep is non-existent. That is referred to as a different condition. REM is actually Rapid Eye Movement. Look it up through google for a prognosis and diagnosis, but all you need to know is its a sleep condition that occurs often in the elderly and children.
During sleep, chemicals called neurotransmitters that have an impact on the brain and whether we are awake or asleep. Another chemical referred to as adenosine in our blood which causes us to feel drowsy or awake.
