movement sleep, especially slow wave sleep, and the processes that take place in the hippocampus during this type of sleep (Payne et al., 2008). In a study conducted by Payne et al. (2008), it was found that sleep that involves rapid eye movement also involves increased response in the limbic system. However, unlike non-rapid eye movement sleep that promotes certain types of hippocampal processes (Drosopoulos et al., 2013), rapid eye movement sleep brings about enhanced behavior in the amygdala, the part of the limbic system that is necessary in the processing of emotionally significant thoughts. The research carried out by Payne et al. provides evidence for a connection between sleep involving rapid eye movement and the increased ability …show more content…
(2008) notes the connection between episodic memory and memory with emotional connotations, pointing out that episodic memories can be triggered by heightened emotional awareness within an individual. This seems to be counterintuitive in light of the fact that episodic memory is related to non-rapid eye movement sleep, and in turn the hippocampus (Drosopoulos et al., 2013), while emotionally significant memory relates more to rapid eye movement sleep and its effect on the amygdala (Sterpenich et al., 2013). One reason for explaining the connection between episodic memory and emotional triggers is offered by a study carried out by Prince and Abel (2013), in which they note the connection between the hippocampus and amygdala, as much of the functioning of the amygdala relates to communication from the …show more content…
(2006), in which it was explained that the first four stages of sleep, which are characterized by non-rapid eye movement, have been described in some cases as continuous in nature, rather than being split into four qualitatively distinct stages. This idea has been supported electroencephalography readings that show a gradual shift in brain activity, and it is relevant in looking at a concept like slow wave sleep (Drosopoulos et al. 2005). If the stages of the sleep cycle are more similar to each other than previously thought, the notion that slow wave sleep only occurs in certain stages of the non-rapid eye movement portion of the sleep cycle becomes questionable (Prince & Abel, 2013). In light of these issues, it is clear that future research is needed to concretely define the differences between the stages of sleep, as there are noticeable discrepancies between the studies of different researchers. A better understanding is needed not just of the nature of the different sleep stages, but it must be determined whether or not all five stages can be viewed as categorically separate from one
The Complexity of Sleep In Matt McCarthy’s Nap Time, he discusses the “most mysterious” of all needs - sleep. McCarthy uses the story of Mike Napoli to introduce this topic. Napoli’s story of his struggle with severe sleep apnea includes some abnormal elements. Firstly, he cites his “first dream in a decade” that he can actually remember (p. 49).
According to David Myers, author of Myers’ Psychology for AP, he details that there are “five main” stages of sleep everyone experiences at night. The stages of sleep play a distinct role in our circadian rhythm, the twenty-four hour cycle of living beings physiological processes (Myers 226). In order to have a full understanding of sleep, it is essential to be able to distinguish between the following stages of sleep: light sleep, sleep spindles, deep sleep, and rapid eye
Rather than normal sleep, scientists decided they were in what is called REM sleep. During REM sleep, also known as rapid eye movement, is when one become sexually aroused, one becomes limp, eyes moved around, heart break and breathing
One of the most common brain activities during sleep is dreaming. Scientist still to this day do not fully understand why we dream or what dreams are exactly. “Some experts suggest that dreams represent the replay of the day’s events as a critical mechanism in the formation of memories, while others claim that the content in dreams is simply the result of random activity in the brain.” It is known that visually intense dreaming occurs most commonly in the REM sleep stage. Dreaming causes the brain to become very active, and not only at displaying the images we see during our dreams.
Sleepless in American is a National Geographic documentary on the lack of sleep Americans are receiving each night. The film starts with the statistic that “40% of American adults are sleep deprived” and followed with different effects of sleep deprivation such as: weight gain, delayed reaction time, depression, anxiety, speeds the growth of cancer, and has been linked to Alzheimer’s disease. Although, there is no scientific evidence to support the need for sleep, it is an important process that allows our bodies to function properly. Several sleep studies have been performed to understand the effects sleep deprivation has on a person. The participants of the sleep trial only received four hours of sleep per night.
N2 The N2 is the slightly deeper stage of N1 and it’s when you lose your awareness of the surroundings. You aren’t still fully immersed in sleep, but more or less unaware of what is happening around you. This stage actually takes up most of your nightly sleep, as it’s roughly 50% of total sleep
The biological approach to the basis of memory is explained in terms of underlying biological factors such as the activity of the nervous system, genetic factors, biochemical and neurochemicals. In general terms memory is our ability to encode, store, retain and recall information and past experiences afterwards in the human brain. In biological terms, memory is the recreation of past experiences by simultaneous activation or firing of neurons. Some of the major biopsychological research questions on memory are what are the biological substrates of memory, where are memories stored in the brain, how are memories assessed during recall and what is the mechanism of forgetting. The two main reasons that gave rise to the interest in biological basis of memory are that researchers became aware of the fact that many memory deficits arise from injuries to the brain.
In this article, “Sweet, Elusive Sleep”, the first paragraph stated by telling a story about a man called Mike Trevino, who is 29 years of age who didn’t sleep all because of a quest to win a 3,000-mile, cross-country bike race. When he later tried to take a nap, he can’t remember his dreams. This case raised important questions such as; “If we don't sleep (or sleep enough), what happens to our dreams? And if we don't dream, what happens to us?” Towards the end, Springen, K. told us what to do if we are having trouble sleeping.
Napping is considered a global and highly prevalent phenomenon that is common in infancy and persists into adulthood for a large proportion of the world’s population. Most of those who get less than the recommended 7 or more hours of nighttime sleep often resort to napping during the day, but this ‘catch-up’ can have both a positive and negative impact on a person’s mental and physical condition. INTRODUCTION Attention getter: Remember back when you were a kid, naps were a daily occurrence?

Watching the Neuroscience of Memory video with Eleanor Maguire I learned more clearly how to perceive and recollect visual scenes. One is given a three second countdown before seeing 2 pictures of the same objects divided by a mash and the challenge was to identify whether the second picture had the same view as the first or whether it moved closer. Our brains are able to travel through time and space, recall places of significance, images, and emotions of past experiences. By virtue of this factor we fear the prospect of memory loss. Many areas of the brain are involved in memory, but one of the most critical components is the hippocampus which can play a crucial role in the formation of long- term memories.
Gaukhar Dosmuratova PSYC 1111 Sleep Deprivation experiments Sleep deprivation is a condition when a person has problems to get enough sleep. Nowadays, sleep deprivation has become a common problem. Sleep plays a vital role in people’s lives because by getting enough sleep at the right times a person can protect his/her mental and physical health. During sleep, your body and mind are resting and it supports healthy brain function and maintain person’s physical health. There are many types of research were made on sleep deprivation.
The brain becomes aware and tries to wake itself up (“Sleep
THE IMPORTANCE OF SLEEPING WELL Hello everybody, I’m going to speak about the most time-consuming activity in our lives: sleeping. As a matter of fact, we usually don’t pay much attention to the quality of our sleep, in spite of influencing a big deal our performance during the day, our health and well-being, in other words, our quality of life. That’s the reason why I would like to introduce some interesting material to understand better this important though disregarded necessity.
