there are two main stages of sleep that alternate at about 90-minute intervals. Those stages are the REM and nonREM sleep. Rapid eye movement or (REM) sleep can be roughly described as a period when the brain is active but the body is paralyzed. Note that you can only dream during a REM cycle of sleep. In non-rapid eye movement or (nonREM) sleep‚ the brain is less active but the body can move. Non-REM sleep is composed of four stages. Your brain goes through each stage of sleep in a continuous cycle

The nature of sleep remains complicated‚ and mostly unexplainable. Sleep is necessary for all mammals. Sleep serves the body as energy conservation processes as well as letting the nervous system recuperate. This bodily recuperation process also allows emotional regulation for the body. The circadian rhythm‚ also known as the biological clock or circadian clock‚ regulates the sleep-wake cycle. The circadian clock is located in a group of cells just behind the optic nerve‚ called the Suprachiasmatic

hibernation‚ in which circumstance it is actually a net loss of energy as the animal returns from hypothermia to euthermia in order to sleep. Physiology: In mammals and birds‚ sleep is divided into two broad types: rapid eye movement (REM) and non-rapid eye movement (NREM or non-REM) sleep. Each type has a distinct set of associated physiological and neurological features. The American Academy of Sleep Medicine (AASM) further divides NREM into three stages: N1‚ N2‚ and N3‚ the last of which is also called

Discuss the nature of sleep ( AO1= 8‚ AO2=16) In this essay I will discuss the nature of sleep‚ in terms of: REM‚ NREM‚ and the physiology of sleep. There are two sorts of sleep: REM and NREM. REM and NREM are as different from each other as each is from wakefulness.

There are 4 stages to NREM sleep: ‘falling’‚ easily woken

During this time the brain gives notions hinting that the person is awake but the person is sound asleep. The only thing that you see is jerky eye movements. In fact if scientists did not see the eye movements of a person in REM‚ they couldn’t have differentiated their brain activity during sleep from the waking state. This was another mystery the scientists were bewildered by and so the experiments began. They found out that during this stage people remember the dreams they
