Sleeps Relationship to Learning and Memory Essay

Sleeps Relationship to Learning and Memory - Essay Example On the other hand, during REM, EEG waveforms change associated with increased frequencies. This is where memorable dreams occur. Sleep in mammals is described mainly by inactivity of behavior in conjunction with different electrophysiological changes in the motion of the brain.ii Factors like stress, shifting schedules, and longer work contribute to lack of sleeping time. This results to inefficient performance to workers so companies have allotted rooms for quick naps and other businesses have installed apparatus that will improve the results short-term sleeps. Sara Mednick et al. (2002) describe naps to be short periods of sleep which lasts for one hour maximum and likely to enhance one's attentiveness, efficiency and disposition. These brief periods of rest are suitable for people, who are experiencing sleep deprivations, nightshift schedules, and prolonged periods of driving. Daytime naps also improve psychomotor speed and attainment of short-term memory. However, their relation on previously learned information is not yet established although they are common among people with daily information overload. Mednick et al. (2002) suggest the psychological feeling of 'burnout', which is an amplified irritation and frustration brought by decreasing effectivene ss after a lengthened cognitive effort, is not merely a reflection of mental exhaustion but a need for a worn-out mind to experience restoration during sleep.iii Sleep is the only 2. Sleep to Human beings Especially Sleep is the only way by which one can rejuvenate oneself; a mere rest will not be any good as far as the revitalizing factor of sleep is concerned. In relation with that, studies also show the need for the brain to experience the restorative benefits of sleep, and also restore positive attitude emotionally. Matthew Walker (2009) identifies several roles of sleep in cognitive and emotional brain processes.iv 3. Sleep and Human Memory Firstly, Walker observes the role of sleep in memory processing which focused on the declarative memory. Secondly, he relates the ordered structure of sleep and memory stage evolution with the sleep-dependent plasticity models. Thirdly, he discusses the role of sleep in associate memory processing. Fourth, he touches on the emerging advantage of sleep in emotional brain reactivity. Lastly, he proposes a framework of sleep-dependent affective brain processing which will further explain the implications of mood disorders. Neurological studies have shown stimulating role of sleep in the control of brain function and emotional experience. Walker identifies that modulation of affective networks overnight and emotional experiences happened in the past are capable of affecting the restoration and maintenance of the appropriate connectivity for the next-day reactivity. Lisa Marshall and Jan Born mention the role of short wave sleep or the NREM, in benefiting the hippocampus-dependent declara tive memory, and also the valuable for the procedural aspects of memory. 4. Sleep and creativityCreativity has been defined by Mednik as the forming of associative elements into new combinations which either meet specified requirements or are in some way useful. Many studies also have explained the roll of sleep in the creative problem solving process. Denise Cai et al. find REM to be beneficial in terms of improving the associative network construction. It has also enhanced the incorporation of unassociated information,
