Non-rapid eye movement sleep

can be used to explain the function of sleep which consist of energy conservation, food requirements, predator avoidance and Meddis’ “waste of time” hypothesis. These theories attempt to explain sleep as an adaptive response which increases the chances of survival. Sleep can be used to conserve energy over long periods of time as metabolism and body temperature decreases. This can be observed in sleeping animals especially in those hibernating during the winter. Furthermore, warm blooded animals such as mammals must use a lot of energy to maintain a constant body temperature. This is more problematic for small animals such as squirrels with high metabolic rates as they use even more energy and hence, sleep…

Q10. There are five different stages of sleep that a person goes through when they are sleeping. These stages are differentiated by the theta activity (slow wave sleep) that takes place in each stage. The first stage that takes place involved theta activity which means the firing of neurons in the neocortex has begun. During this level of sleep there is an EGG level of 3.5-7.5 HZ. The EEG level is the electrical activity that takes place within the brain, it is recorded through electrodes that…

This topic of non-dreamers was chosen because people do dream. Dreams are important because dreams prove REM sleep was entered. REM sleep is the type of sleep which rapid eye movement occurs. Muscle activity can also be occurring. The online source took the textbook one step further because more research was studied. Discovering Psychology written by Hockenbury, et al was edited and published in 2016 where as Evidence That Non-dreamers Dream: A REM Sleep Behavior Disorder Model written by…

However, the dream that individuals have occur during the rapid eye movement sleep where we think and see different things in our mind. Furthermore, in the non-rapid eye movement sleep each stage can last up to five to fifteen minutes. In stage one, even though the eyes of a person is closed it is easy for the person to wake up. Stage two, the person is in light sleep where your heart rate and temperature goes down where your body starts preparing itself for deep sleep. Stage three, it becomes…

reported “Terror gripped the young man, who couldn't move a muscle, his eyes plastered open in fright… an oppressive weight compressed his rib cage. Breathing became difficult, and Hufford felt a pair of hands encircle his neck and start to squeeze” (Bower). Our conscious brain slips into unconsciousness as we fall asleep or transitioning into wakefulness. Fantasy and reality blur and people often report hearing or seeing things that are not there. During rapid eye movement (REM) sleep, where…

Psychology – Sleep Assignment Title: Snoozzzze before you losssse What is Sleep? Sleep is described as a non-waking state of consciousness that is characterised by general unresponsiveness to the environment and physical immobility. Sleep is when the nervous system of your body is inactive and the muscles are relaxed. Why do we sleep when we do? Humans tend to sleep 5-8 hours every night, and to do so in a pattern tied to the 24-hour light-darkness cycle. This cycle is called a circadian rhythm…

When you fall asleep, you enter a deep sleep cycle called REM sleep. REM means Rapid Eye Movement. When you enter this cycle, you get the deepest sleep, but it’s also when you begin to dream those vivid dreams you probably don’t remember when you wake up. Sure, if you’re untrained, you will only remember bits and pieces of them, but not enough to differentiate one dream from another during REM sleep. What if you could turn your dreams off altogether? At the University of California, Berkeley,…

these mammals have to sleep in a way that prevents them from drowning, which is different from how you and other land mammals sleep. Your bodily functions during sleep include the inactivation of all voluntary muscles, however, you are equipped with a breathing reflex which allows you to breathe automatically so you will not suffocate during sleep. Dolphins aren't equipped with that breathing reflex, so their way of sleeping is very different and is important to their survival. Unihemispheric…

discrete from the conscious mind. They are a sequence of mental representations or ideas that the mind generates during sleep. While dreams have captured the attention of people all around the world, this profound topic has led to additional questions and numerous answers.The stages of NREM sleep, lucid dreams, and the effects of dreams are subtly expressive. There are many theories that state why people dream, however, the reason as to why dreams occur is not scientifically proven. Some…

environment, during sleep this awareness fades, but does not shut out completely. Licht, Hull & Ballantyne (2014).Consciousness is sometimes equated to being awake and unconsciousness equated to being passed out. There are several different levels of consciousness. These states include wakefulness, sleepiness and dreaming. These are only a few names of the altered states of consciousness. Sleep needs can range from 4 hours to 11 hours per night, but most people sleep for 7 to 8 hours. The brain…
