Many scientists all over the world have all attempted to explain the physiological and psychological effects of peoples sleep and dreams. In spite of this, up until this century and with few exceptions, everyone has always thought that while a person slept, their body and brain went into an inactive state. It wasn’t until 1928 when a German psychiatrist that goes by the name of Hans Berger discovered electrical activity inside of the human brain and distinguished differences in these rhythms when the patients were sleeping and when they were awake. It wasn’t until many years later that rapid eye movement (REM) sleep, or dream sleep as some call it, was described. When the convincing evidence of this was provided from studies that the brain is very much active during REM sleep and while certain areas or parts of the…
This stage is also called paradoxical sleep. During a dream, the dreamer experiences an incredibly lifelike ordeal, and the shutting down of the self-awareness causes them to encounter the dream in a first person point of view, generally without the knowledge of who they are and being unable to control the circumstances, and is also almost never aware that they are even dreaming. Dreams can last from five minutes…
In the first ten minutes of sleep, it’s very light and you are very vulnerable to being disturbed by your roommate. This is the stage of sleep where people often get myoclonic jerks. After these ten minutes, we reach the second stage and brain waves are slowing down further. Noticeable effects of this stage are a slower heart rate, heavier breathing, and your body temp will decrease as well. Also, we go through K-Complexes with are sudden bursts of electrical brain activity.…

Oswald suggests that sleep is the ideal time for the body to replenish itself in addition the repair of damaged cells. Oswald also believes that during REM sleep the high levels of brain activity could indicate brain recovery and the increased levels of growth hormones during Slow Wave Sleep indicates the recovery of the body. This supports the idea that REM stages of sleep are important in restoring the body to its optimal state. New-born babies exhibit a vast amount of REM sleep. REM Sleep takes up about 60% of total time asleep in new-borns the decreases to about 25% as the child ages.…
These are often referred to as “NREM and REM sleep. NREM sleep occurs before dreaming, meanwhile, REM sleep occurs when the sleeper is dreaming. NREM stage one is the first stage the sleeper starts off at. Stage one concludes of light sleep and slower breathing. After approximately one to ten minutes, NREM stage two begins, where the body activity reduces to prepare to go into a deep sleep which includes the heart rate, body temperature, blood pressure, and other metabolic functions.…
The biological approach relates to sleep as it’s theories involve bodily processes and functions. The biological approach explores events that occur within the body. Sleep is important as our bodies need sleep to function as certain functions are restored within the body. The biological approach states that sleep occurs in a circadian rhythm known as the sleep-wake cycle occurs over a 24-hour period. The hypothalamus is located in the brain and contains the superchiasmatic nucleus (SCN) which controls the circadian rhythm.…
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.…
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…
In Chapter three I found the sleeping stages very interesting. I think that it is amazing that there are four total stages of sleep once you start sleeping. Also, it is cool that about every ninety minutes, you cycle through four distinct sleep stages. Out of all the stages the one that caught my attention the most was the last stage, the REM stage. This stage surprised me the most because it said that this stage arouses people the most, especially if you were to have a nightmare.…
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.”…
Common delusions include cheating spouses or theft. Delusions mainly occur in advanced Parkinson’s. REM sleep behaviour disorder -REM (rapid eye movement) sleep is one of the five stages of sleep. Normally, there is no movement during REM sleep (you are paralyzed). If you have REM sleep behaviour disorder (RBD), this normal paralysis is lost.…
The brain is as active during REM sleep as being awake. When we dream, our eyes tend to move and see pictures in our head. That’s why you can open someone eye lid and you can see their eye moved. Walking states of altered consciousness is associated with meditation, hypnosis, and drug use.…
There are approximately 3 stages of sleep. During stage 1, you are in-between wakefulness and sleep and your muscles are still active and your eyes will open and close a few times. Your heart rate slows and your breathing pattern becomes regular. During stage 2, your muscle activity goes down and you are basically unconscious to the outside world. During the 3rd and final stage of sleep (also called deep sleep), the sleeper is completely unaware of what is going on outside of their dreamland.…
