Introduction

Outline the findings of studies into sleep deprivation and assess their implications for one or more theories of sleep. In this essay, I will be looking into 4 different studies of total and partial sleep deprivation and will be assessing their implications for Restoration theory of sleep. According to restoration theory, the purpose of sleep is to repair and recharge the brain and body through restoring energy resources, repair and growth of tissue cells and muscles, and replenishing neurochemicals. Firstly, I will be looking into total sleep deprivation research. Peter Trip, a New York DJ took part in a 'wakeathon' for charity he stayed wake for 8 days, which resulted in delusions and hallucinations. ...read more.

Middle

The effects included distress as a consequence of lack of sleep, strong desire to sleep, periods of micro-sleep and delusions. There is no standardisation of the methods employed and as it secondary research we cannot be absolutely sure of the methodology. However this study show that sleep deprivation can have negative effects and can be applied to the real world. It also supports restoration theory of sleep. Rechtschaffen et al (1983), two rats were placed on a disc above water, one was able to sleep and the other one wasn't as when the EEG indicated that sleep began the disk would move and so the rat fell into the water. The sleep deprived rat's died within 33 days and the rats that not deprived of sleep suffered no ill effects after the study. ...read more.

Conclusion

This study supports Horne theory of sleep who distinguished between core (stage 4 and REM) sleep and optional (stages 1 - 3) sleep and claimed that only core sleep was critical for restoration of the brain as restoration of the body can occur during wakefulness. This is also supported by Stern and Morgan. Dement study does show that when deprived of REM sleep it can have more negative effects that NREM deprived sleep. To conclude, both partial sleep deprivation and total sleep deprivation can have negative effects and in some cases lead to death. Restoration Theory does have face validity as it makes sense and is highly plausible. There is also a need for further research into neurochemicals and the effects of sleep deprivation on health. ?? ?? ?? ?? Christopher Ball ...read more.

    The theory of dynamic stabilization also proposes that REM sleep increases the activity of neuron circuits which are usually dormant during wakefulness. In other words, memories which we don't think about from day to day are relived during REM sleep (in the form of dreams)

    They naturally occur at a rate of one per minute. Some researchers believe that sleep spindles and K complexes help us disconnect from the outside world (noises, etc). This stage lasts only for a few minutes. Stage Three After about a total of fifteen minutes, we are ready to enter stage 3.

    He was clearly less affected that Tripp by sleep deprivation, even though he did remain awake for an extra 3 days. There were two other cases that involved animals; rats and cats. Rechtschaffen looked into sleep deprivation with rats. He used two rats at a time, he put rats on two disks above water and their EEG activity was monitored.

    This shows that it is NREM sleep that is important for energy conservation and can therefore partially contribute to the explanation of the function of sleep. On the other hand, it has been found that sleep does not conserve a great deal more energy than when resting, sleep reduces energy rates by 5-10%.

    This system is argued to be evolutionary useful in that a person who is 'weighted' towards more responses to possible threats, even if some of these constitute false alarms will have a greater chance of survival. And it is these false alarms that are described as 'cognitive misinterpretations' in the clinical literature (Clark, 1986, 1988; cited in Windmann, 1998).

    If either of these 2 cycles are interrupted a numerous amount of times every night, we suffer by not being able to accomplish an easy task or having difficulty in everyday events. These interruptions are due to noises caused by things or other people, room temperature and light, or by sleeping disorders the individual has.
