Outline and evaluate restoration explanations for the functions of sleep [8 + 16] intro: Aleep is divided into several different stages. SWS and REM sleep are associated with particular benefits. Oswald (1980) proposed that each of these had different functions - slow wave sleep enables body repair and REM enables brain recovery. SWS – initiates body repair (Oswald) Growth hormone – important in childhood because it stimulates physical growth. Important throughout lifespan for protein synthesis

person is awake‚ it is necessary to understand sleep cycles. In a mammalian sleep‚ the brain activity undergoes two different states called non-REM (NREM) sleep and REM sleep‚ which differ very much from wakefulness . NREM and REM sleep alternate cyclically through the night; in human‚ about 80 minutes of NREM sleep starts a night of sleep‚ about 10 minutes of REM sleep follows‚ and this 90 minute cycle is repeated about 3 to 6 times during the night . During NREM sleep‚ a body produces few movement‚

had to leave for class in 45 minutes‚ I told her no. She responded with “But 45 minutes is the perfect timing for a nap! It’s long enough to get deep sleep‚ but not long enough to enter the REM stage.” If that were in fact the exact right amount of time to enter deep sleep without having time to enter the REM stage‚ that would be the very reason to not take a nap of this time. Why‚ as people requiring more sleep than the average adult‚ do college students not know more about napping?

overlap of the REM and waking stages of sleep. During a normal REM cycle you’re experiencing a number of sensory stimuli in the form of a dream‚ and your brain is unconscious and fully asleep. During your dream‚ special neurotransmitters are released which paralyze almost all of your muscles. That’s called REM atonia. During an episode of sleep paralysis you’re experiencing normal components of REM‚ dreaming‚ muscles paralyzed‚ but your brain is conscious and wide awake. Also during REM‚ the function

During sleep‚ it is essential to go through all the sleep processes such as REM (rapid eye movement) and Non-REM sleep. A study done by Ross‚ et al. (1994) showed that PTSD sufferers do not achieve proper REM sleep. REM sleep is crucial for memory consolidation; however‚ it is also the time in which the amygdala is most active (BBC‚ 2009). The amygdala is a structure in the brain responsible for

These conscious states are very important‚ even if we are unaware that they are occurring at times. From the lowest level of consciousness‚ which is REM or Delta brain waves‚ to your most alertness‚ which is Beta brain waves‚ they are all so important and needed daily. Most importantly‚ everyone needs REM sleep‚ which is the deepest sleep stage‚ so that they can be alert when it is needed. Consequently‚ sleep deprivation leads to lack of awareness‚ and the inability to accomplish

Studies have shown that the brain is as active during sleep as it is when awake. Throughout an eight-hour sleep cycle‚ a normal adult alternates between two very different states‚ non-REM and REM (Rapid Eye Movement) sleep. Sleep is characterized by two distinct states‚ non-REM sleep and REM sleep. Non-REM and REM sleep alternate in 90- to 110-minute cycles. A normal sleep pattern has 4-5 cycles. The diagram and descriptions below illustrate the architecture of sleep. This explains why the cycles

Most people believe that they don’t dream‚ only because these individuals can’t recall dreaming as an event. In J. Allan Hobson’s book‚ Dreaming‚ it explores how dreaming is influenced and how it affects the individual‚ how dreaming is associated with REM (Rapid Eye Movement) sleep and the importance of it‚ and also why sleep is so essential for human beings and other mammals to experience. Sleep is correlated with dreaming‚ making dreaming a phenomenon essential to living. Dreaming is an interesting
