The activity levels in the brain differ from Non REM and REM dreaming. The brain is most active in REM dreaming with parts such as the Brain Stem, Visual Association Area, Motor Cortex and Amygdala activated. Though there are many active areas of the brain in REM dreaming there are also inactive areas as well; like the Prefrontal Cortex. For Non REM dreams…
What is a dream? The scientific definition of a dream is when there is a very small amount of brain activity and there is no sense of self-awareness. Most dreaming occurs in the REM (rapid eye movement) stage. This is the stage during which accelerated respiration and heart rate, muscle relaxation, and increased brain activity occurs.…
The argument of “Rethinking Sleep”, by Davis K. Randall, is people should consider sleeping in segments rather than 8 hour blocks. The two reasons are, naps with deep sleep help brains function at a high level, and segmented sleep improves daytime performance. Two more important pieces of evidence for the first reason are , “...recent studies suggest that any deep sleep- whether in an eight-hour block or a 36-minute nap- primes our brains to function at a higher level, letting us come up with better ideas, find solutions to puzzles more quickly, identify patterns faster, and call information more accurately. ”(lines 51-54), and “ Researchers at the City University of New York found that short naps helped subjects identify more literal and…
Diminished productivity, slow reaction time, and increased irritability are all effects of? As Cori sits in class, she starts to feel herself dozing off. Which stage of sleep is Cori in? Heart rate rises and breathing becomes irregular in which stage of sleep?…
Dreams have a psychological purpose, but any discrepancy in the normal function of sleep can cause major mental and physical issues. The human body usually doesn’t realize the brain is just “playing pretend”, and if given the opportunity, the body will act out those dreams. This can lead to a condition called REM sleep behavior disorder, which can be incredibly dangerous. In normal conditions, the brain also has a “safety valve” which basically causes the body to paralyze itself during REM sleep to prevent you from physically executing the events of your dreams. While you dream, neural activity spreads through the cortex causing the images we experience.…
Psychology Assessment 1a) The Cognitive Approach The Cognitive Approach to Sleep and Dreams can be defined simply by the computer analogy. The key purpose of sleep is to store, input and output information collected throughout the day and process that information into some kind of order, this could explain why our dream content is mostly based on issues faced during the day. While we are asleep our mind processes information and then consolidates important memories and also discards useless information. Sleep has been proven to be directly linked with memory.…
During REM sleep, rapid eye movement occurs as we dream and the brain becomes more active causing faster brain waves and deeper sleep. Most of our sleep occurs in the NREM sleep stages where brain waves are slower. The restoration theory states that NREM sleep is needed to restore physiological functions. Growth hormones are secreted during NREM sleep which is particularly important for the growth of children along with protein synthesis and cell growth. Cells in the body are constantly renewed which makes sleep vital in allowing cell growth.…
Sleep is, perhaps, one of the most confounding aspects of humanity, even to this very day. There is a host of theories as to why humans require sleep, as well as a similar variety of theories as to why sleep brings dreams. Some say that they are simulations - a means originally produced by the brain to help humans prepare for particular events they have yet to encounter in reality. Others say it is to de-stress the mind, to unravel the complicated webs of data collected through our senses throughout the day. Regardless of the specifics, I have always been a dreamer, and a vivid one at that.…
During the sleep cycle, the nervous system is inactive, muscles are relaxed, consciousness is suspended, and the body is restored. During sleep, we can experience various dreams. Not only do people experience dreams, they also experience nightmares of certain situations such as teeth falling out, being chased, falling and more. Children and adults both experience nightmares. The Huffington post reported that 10-50 percent of 3-6 year olds experience nightmares that affect their sleep.…
In a typical sleep cycle, you enter many different stages of sleep throughout the night. You enter early stages of sleep then followed by deeper sleep stages and eventually rapid eye movement best known as REM sleep, During REM sleep is when you experience dreams, REM sleeping usually occurs after about 90 minutes into the sleep cycle and occurs intermittently…
Studies show that 80% of people awakened during REM sleep reported dreams. However dreams were also reported during NREM (non-REM sleep) sleep and were described less wild than REM dreams and more…
Though many aren’t surprised about the simple “treatment” for a peaceful REM during their sleep cycle, many aren’t fully aware of what REM really is. What Is REM? Rapid eye movement is one of three stages of “sleep”,…
A completed cycle of sleep consists of a progression from stages 1-4(non-REM) before REM sleep is attained, then the cycle starts over again. One sleep cycle costs around 90 minutes. In fact, there is no particular number to show how long that sleep cycle is that people really need. However, it is important for people to process the full stages while sleeping, which means people must enter non-REM then get into REM to ensure a good sleep. “It has been hypothesized that REM (rapid eye movement) sleep has an important role in memory consolidation.”…
Dreams are an essential part of our sleep. They are a series of thoughts, images and sensations occurring in a person’s mind while they are asleep. Often when we have dreams whether good or bad and when we wake up it’s hard to remember what the dream was about. Scientists define dreams as hallucinatory images. According to Myers, REM dreams are “hallucinations of the sleeping mind and are vivid, emotional and bizarre, so vivid that we can confuse them with reality.”…
An EEG, electroencephalogram, is a test that detects electrical activity in the brain using electrodes attached to the scalp. Brain cells communicate via electrical impulses and are active at all times, even during sleep (Nir 2010). One set of EEGs completed by The National Center for Biotechnology Information, showed that there are similarities in the brain waves of a person who is awake and one that is dreaming in REM sleep. The data showed that the REM sleep’s low amplitude waves, 4-7Hz, were the same as the brain waves recorded in the person’s wake state of mind (Nir, 2010). The theory behind these results is that several parts of the brain are being stimulated during dreaming.…
