Rapid eye movement sleep

Sleep Homeostasis, Sleep Deprivation, and Slow Wave Activity Vahan Hovannisian Mrs. Lee AP Biology 10A 18 October 2016 Hovannisian 2 In all species of animals that have ever been studied, sleep cycles are regulated homeostatically. This means that longer an animal stays awake, the longer and deeper the next sleeping period will be. Slow wave activity (also known as SWA), or slow wave sleep, is deep-sleep. If an organism is sleep deprived for a long period of time, there will be…

For many, the process of sleep is a mystery. It is difficult to imagine what brains do during sleep, why human dream, or even why human face some nightmares during their sleep. The purpose and content of dreams or nightmares for some individuals are still ambiguous even though dreams are a phenomenon notion for everyone. Dreams are maintained in short memory in brains, and individuals might remember them for a while. Consequently, human often cannot recall exactly what they see in their dreams,…

2.0 STAGES OF SLEEP 2.1 Non-Rapid Eye Movement (NREM) Sleep Non-rapid eye movement (NREM) sleep can be characterized into three distinct stages, previously classified into four stages. NREM sleep can be differentiated from rapid eye movement (REM) sleep due to its lack of muscle paralysis and bursts of eye movement typically observed in REM sleep3. Additionally, NREM sleep demonstrates characteristic waves and spindles captured on electroencephalogram (EEG) readings that differ significantly…

noticed that when you get the proper amount of sleep and rest that you feel better? Your thinking is clearer, you can complete all the things on your to-do list and you have more energy. Without the proper rest you make more mistakes, your cognition is slower and you lack energy. Failure to get the proper rest jeopardized your overall health. Sleep promotes and contributes to psychological and physiological restoration of the body. During sleep, your bodies biological function slow down.…

Importance of Sleep As we all know, our time on Earth is limited. One of the most valuable resources that we have is time. Knowing this makes us want to use our time as efficiently as possible. You may realize that no matter how well you use your time, there still may not seem to be enough. At this point you may wonder where you can get more time. With the Fountain of Youth out of the picture, a place many people turn to (or rather away from) is their bed. We humans spend about one third of…

Rapid eye movement sleep is a unique phase of mammalian sleep characterized by random movement of the eyes, low muscle tone throughout the body, and the propensity of the sleeper to dream vividly. This phase is also known as paradoxical sleep and sometimes desynchronized sleep because of physiological similarities to waking states, including rapid, low-voltage desynchronized brain waves. Electrical and chemical activity regulating this phase seems to originate in the brain stem and is…

“ Sleep is the golden chain that ties health and our bodies together” - Thomas Dekker The thought of your eyes moving rapidly in your head isn’t the most flattering thought, yet it’s something that happens about four - to- five times every night during our sleep cycle. Rapid eye movement, or REM, has many stages and though seeming completely harmless, in actuality can cause injury to people and their loved ones. REM is also capable to cause future health concerns, yet the capability to prevent…

morning from my sleep, which was about 6-7 hours this sleep was composed of Non-Rem (non-rapid eye movement) and Rem (rapid-eye-movement). Once, I woke up I took a shower and ate some breakfast to get my day started. Later, In the day I went to class, and we where required to do experiments, this allowed my brain to produce beta-waves. During this class, I felt very conscious in this class due to, all the engagement that is needed when conducting different experiments. An EEG would show rapid…

8 hours of sleep daily, but never knew exactly why. Due to me not knowing the meaning of acquit amount of sleep I form the mentality that sleep is sleep, right? However in reality, while the body is at rest there is still a lot going on inside of our head due to the activity of the brain. In today’s society we are taught there are two main type of sleep: Non- Rapid Eye Movement (NREM) which is also known as the quiet sleep and consist of four stages in which we move from a light sleep during…

you think you sleep because your body is tired but do you know the real reason you sleep? The answer is quite simple you need sleep to live (Hauri 20).Aside from keeping you alive sleep has many benefits including, removing toxins from your body. Just as having the right amount of sleep benefits you, being deprived of sleep has many consequences. Sleeping seems like a simple task but it is actually quite complicated, there are many factors to falling asleep such as the 3 stages of sleep. For…
