Abstract:
Sleep has become less important in western society during modern times, where many have the habit of prioritizing productive activities instead of sufficient sleep. However, recent studies have indicated the importance of sleep for emotional processing. A crucial finding in literature regarding sleep and emotions has been the enhancement of negative emotions after sleep deprivation. The aim of this systematic literature review was to investigate the neural basis of the effects of sleep deprivation on emotional reactivity. In order to conduct this review, three databases were used to obtain relevant articles. Out of the total 1041 articles, 11 fulfilled the inclusion criteria and were included in the review. The selected articles exclusively contained results regarding reactivity to visual emotional stimuli. Results showed that total and partial sleep deprivation result in enhanced amygdala activity in response to negative stimuli. Enhanced amygdala activity was also found in response to positive and neutral stimuli after sleep deprivation. The insula was another brain region that displayed enhanced activity toward all types of valenced stimuli after sleep deprivation. Moreover, weaker connectivity between the amygdala and prefrontal areas (specifically the medial prefrontal cortex) was found after total and partial sleep loss. Together, these results suggest that sleep deprivation induces hyperreactivity toward emotional stimuli and disrupts top-down regulation of emotional reactivity.

Abstract:
Background: The high availability of palatable, calorie dense and nutrient poor foods promote hedonic eating, defined as the drive to eat to obtain pleasure in the absence of an energy deficit. Poor sleep and hedonic eating, independently, drive obesity at the societal level. However, it is unknown whether the combination of sleep loss and access to palatable food synergistically increases weight gain. Objective: The purpose was to test whether chronic partial sleep deprivation by a method that increases weight gain also increases hedonic eating and exacerbates weight gain in rodents. We hypothesized that 1) type of diet, 2) preference for the diets and 3) sex would moderate the effect of sleep loss on calorie intake and weight gain in sleep deprived rodents. Subjects/Methods: Three-month old male and female Sprague-Dawley rats (n = 58 males and n = 10 females) were acclimated to hedonic diets for 7-d and then exposed to pre-recorded environmental noise (8h/d for 9-d). Body weight was measured every other day, unless mentioned otherwise. Food intake, corrected for uneaten food, was measured daily. Results: Noise exposure did not affect body weight gain and total calorie intake among male rats who had access to both a high and a low-fat diet. The effect of noise exposure on chocolate intake differed between male rats who were classified as high or low preference for chocolate. Initial preference for chocolate was greater in females compared to male rats. Conclusions: These results highlight the importance of preference and sex when investigating the effects of partial sleep deprivation on hedonic eating and obesity.

Abstract:
College students are some of the most sleep deprived people in the nation. They have some of the worst sleep hygiene behaviors compared to other adult groups. Most people benefit from at least 7 to 8 hours of sleep each night, which is an adequate amount of time for a person to complete a regular sleep cycle. When students lose sleep, they disrupt their sleep cycles and their bodies respond by decreasing their ability to concentrate and complete complex tasks. This paper investigates the factors that contribute to sleep loss, and the correlating effects that it has on college students' academic performance.

Abstract:
This thesis describes the use of in vivo and in vitro models to better understand the molecular correlates of sleep and sleep deprivation. Unlike previous studies, we utilise a timecourse based experimental design throughout, which has the advantage of identifying how the abundance of molecules return to baseline following sleep deprivation. Chapter 3 outlines the transcriptome of mouse cortex collected over 54 hours from mice subjected to varied durations of sleep deprivation. The timecourse experimental design aids in the identification of genes that are induced during both spontaneous and enforced wakefulness, and facilitates the dissociation of genes whose expression is tightly linked to the current wake state of the animal from those whose expression is linked to the total amount of wakefulness recently experienced by the animal. Like previous studies, we identify several genes involved in the unfolded protein response and synaptic function that are upregulated by sleep deprivation. We also find that increasing durations of sleep deprivation progressively reduces the total number of rhythmically expressed genes in mouse cortex, with only a handful of transcripts identified as diurnal following 12 hour sleep deprivation. Chapter 4 outlines the proteomic and metabolomic effects of 12 hour sleep deprivation. Proteomic analyses indicate that the abundance of ribosomal and nucleosomal proteins is suppressed for at least 24 hours following sleep deprivation, whilst the abundance of several phosphodiesterases are acutely increased following sleep deprivation. Metabolomic analyses of sleep deprived mouse cortex identified 3 molecular species whose abundance profile implicate them as sleep homeostats. Finally, we also set out to develop an in vitro model of sleep deprivation based on the optogenetic activation of a neuroblastoma cell line, which is outlined in Chapter 5. Following several rounds of optimisation, the stable expression of an opsin was found to induce intracellular calcium spikes and immediate early gene expression during illumination. Transcriptomic profiling of illuminated SH-SY5Y cells induced large scale transcriptomic changes, and modulated the expression of genes involved in synapses, cholesterol synthesis, the molecular clock and the unfolded protein response. Although these functional classes are reminiscent of those modulated by in vivo sleep deprivation, there was only a slight enrichment of individual genes modulated by in vivo sleep deprivation amongst the blue light sensitive genes, indicating further work is required to more closely model in vivo sleep deprivation.

Abstract:
Sleep deprivation is a multifactorial phenomenon, occurring frequently in the intensive care unit (ICU) and linked to adverse patient healthcare outcomes. The key practice question of this project focused on determining if retiming of routine laboratory and imaging testing outside of the designated “quiet time” can improve sleep quality among adult patients in the ICU. The purpose was to evaluate the effectiveness of implementing an evidence-based intervention to improve sleep quality in the ICU setting. The theoretical framework was the plan-do-study-act model, which offered a process for implementing a practice change and reevaluation of the intervention’s sustainability within the organization. A thorough literature search of over 100 scholarly journal articles, book references, and expert scholarly reports was completed to gain an understanding of this phenomenon in the ICU setting. The Richards-Campbell Sleep Questionnaire (RCSQ) was the data collection tool used to measure improvement in sleep quality. There were 72 participants that are included in the project. The Wilcoxon rank sum and chi square tests were used for the statistical analysis. The findings did not show statistical significance in the improvement in the RCSQ scores after implementation of the intervention. The recommendations include sleep deprivation training for nursing staff and providers, routine use of the RCSQ for data collection, and repeating the study with an increased number of participants and redefined inclusion and exclusion criteria to be more representative of the ICU patient population. The implication for social change is that this project empowers nursing to embrace a leadership role in using evidence-based practice to change clinical guidelines and improve patient outcomes.

Human errors in attention and vigilance are among the most common causes of transportation accidents. Thus, effective countermeasures are crucial for enhancing road safety. By pursuing a practical and reliable design of an Active Safety system which aims to predict and avoid road accidents, we identify the characteristics of drowsy driving and devise a systematic way to infer the state of driver alertness based on driver-vehicle data. Although sleep and fatigue are major causes of impaired driving, neither effective regulations nor acceptable countermeasures are available yet. The first part of this thesis analyzes driver-vehicle systems with discrete sleep-deprivation levels, and reveals differences in the performance characteristics of drivers. Inspired by the human sleep-wake cycle mechanism and attributes of driver-vehicle systems, we design and perform human-in-the-loop experiments in a test bed built with STISIM Drive, an interactive fixed-based driving simulator. In the simulated driving, participants were given various driving tasks and secondary tasks for both non and partially sleep-deprived conditions. This experiment demonstrates that sleep deprivation has a greater effect on rule-based tasks than on skill-based tasks; when drivers are sleep-deprived, their performance of responding to unexpected disturbances degrades while they are robust enough to continue such routine driving tasks as straight lane tracking, following a lead vehicle, lane changes, etc. In the second part of the thesis we present both qualitative and quantitative guidelines for designing drowsy driver detection systems in a probabilistic framework based on the Bayesian network paradigm and experimental data.
(cont.) We consider two major causes of sleep, i.e., sleep debt and circadian rhythm, in the framework with various driver-vehicle parameters, and also address temporal aspects of drowsiness and individual differences of subjects. The thesis concludes that detection of drowsy driving based on driver-vehicle data is a feasible but difficult problem which has diverse issues to be addressed; the ultimate challenge lies in the human operator.

Abstract:
In this study, I investigated the effects of sleep deprivation on cheating behavior. I proposed that sleep deprivation results in cognitive depletion. Cognitive depletion should impair an individual's ability to reason against unethical impulses such as cheating. In addition, I proposed that moral disengagement as a personality trait affects the extent to which sleep deprivation is linked to cheating. Results from a laboratory study show that sleep deprivation is indeed associated with higher rates of cheating behavior. Additionally, this relationship is stronger among individuals who are higher in moral disengagement. These findings provide support towards the interactionist and person-situation models of ethical decision making. Both of these theoretical models state that situational antecedents and individual differences interact to influence outcomes of ethical behavior.

Abstract:
Sleep deprivation affects the academic performance of online university students, and students who have family responsibilities and a full-time job have a higher prevalence of sleep deprivation. This phenomenological study examined the lived experiences of online university students regarding sleep patterns, sleep deprivation, and the impact on their academic performance. The theoretical foundation for this study was based on the opponent processing model that explains the 2 fundamental processes necessary for individuals to function at their optimum ability: the sleep-wake homeostatic process and the circadian rhythm processes. The research question explored the beliefs and perceptions of 10 online university students, while the sub questions focused on how distractions, social media, family, and work-related duties affected their sleep patterns. Purposeful sampling was used to recruit the participants who were current online university students, with a full time job, a family and family responsibilities. Data were analyzed through pattern coding and structural analysis. Four themes emerged from the analysis of the data: the effects of sleep deprivation, adjustment to daily lives, factors affecting sleep deprivation, and impressions of online education. Results demonstrated that sleep deprivation causes tiredness, sluggish thinking and cranky responses. Positive social change can be achieved if the 10 participants participate in building a community of online university students who will maintain an alumni base that can foster mentoring and empowering others to decrease sleep deprivation that helps in maintaining good academic standards.

Full text
Abstract:
Most sleep loss research has concentrated on long duration, repeated measures performance of low-level, monotonous tasks, such as vigilance and reaction time, in support of the theory that sleep loss induces a decline in Non-Specific arousal while having no specific effects on functioning. Numerous studies have shown the beneficial effects of caffeine on this type of performance measure. Recent studies have been conducted on executive functioning tasks that are short, novel, and stimulating. These measures display a sensitivity to sleep loss after 36h that is not compensated by waking countermeasures such as motivation and caffeine. These findings suggest Specific effects of sleep loss, contrary to the Non-Specific theory, particularly on tasks associated with frontal lobe activation. Similarities between performance deficits following brain lesions and those observed in sleep loss subjects form the basis of a neuropsychological model of sleep function. This thesis was an endeavour to document the findings of executive functioning sensitivity following 27 and 36 hours of sleep loss, testing the effect of two common countermeasures, caffeine and a nap. It was established that the critical period of sleep loss for executive functioning performance is at 36 hours. Sleep deprivation effects for periods shorter than 36 hours can be countered by a waking countermeasure, caffeine. It was further established that a 2-hour prophylactic nap opportunity inhibited sleep deprivation effects at 36-hr performance testing for executive functions. The systematic analysis of the effects of sleep loss on language skill, a complex task which is possibly an executive functioning task associated with frontal lobe activation but largely neglected in the literature, detected an increase in variability in language skill, and a propensity towards production errors in speech, but not writing, at 36 hours without sleep. This effect was not observed at 27 hours. The findings are discussed in support of a hypothetical consolidated model of Specific and Non-Specific Effects of sleep loss.

Abstract:
The hypocretin peptides are two hypothalamic peptides known to be involved in both sleeping and feeding behavior, however their specific roles in these domains are not well understood. The present study sought to determine the effect of chronic (72-hour) sleep deprivation and (48-hour) food deprivation on preprohypocretin (PPH), which is the precursor for the hypocretin peptides. PPH levels were visualized and quantified via in situ hybridization. A three-factor ANOVA ( group x dorsal/ventral x medial/lateral) revealed a significant effect of subregion, specifically dorsal/middle and ventral/medial exhibited elevated PPH levels, however there was no effect of group. A between group one-way ANOVA revealed no effect of group on PPH levels. It is theorized that four possible domains may be responsible for these results: presence of hypothalamic neuronal subpopulations, role of circadian rhythm, role of hypocretins in locomotive behavior and inextricably confounded variables. These are discussed at length.

Abstract:
Situé dans le noyau suprachiasmatique (SCN) de l’hypothalamus, l'horloge principale contrôle les rythmes des processus comportementaux et métaboliques chez les mammifères. Par exemple, les rythmes quotidiens de veille-sommeil, d'alimentation-jeûne, de glycémie, de tolérance au glucose et de sensibilité à l'insuline sont régulés par l'horloge SCN. La lumière est le synchroniseur principal du SCN, même si de nombreux facteurs autres que la lumière, tels que l'éveil comportemental ou des facteurs métaboliques, peuvent également moduler la phase ou la période des SCN. L'objectif de cette thèse était d'étudier différents aspects des interactions entre l'éveil comportemental, les rythmes circadiens et le métabolisme du glucose. Dans la première partie, nous avons déterminé l'action centrale du Gastrin-Releasing Peptide (GRP), un neuropeptide synthétisé dans le SCN, sur le métabolisme du glucose. Nos résultats indiquent qu’une injection icv de GRP induit une hyperglycémie prolongée. Nous avons également montré qu’une privation de sommeil à court terme conduit à une détérioration de la tolérance au glucose. Dans la deuxième partie, nous avons démontré que l'éveil comportemental induit par la privation de sommeil ou une injection de caféine améliore l’entraînement photique de l'horloge SCN chez un rongeur diurne : le rat roussard du Soudan, Arvicanthis ansorgei. Ces réponses circadiennes chez une espèce diurne qui sont opposées à celles précédemment mises en évidence chez les rongeurs nocturnes pourraient avoir des applications biomédicales
Located in the hypothalamic suprachiasmatic nucleus (SCN), the master clock generates rhythms of behavioural and metabolic processes in mammals. For example, daily rhythms of sleep-wake, fasting-feeding, plasma glucose concentration, glucose tolerance and insulin sensitivity are regulated by the SCN clock. Light is the primary synchronizer of SCN pacemaker though many light-independent factors such as behavioural arousal and metabolic cues also have phase and period resetting properties. The aim of thesis was to study different aspects of the interactions between behavioural arousal, circadian rhythms and glucose metabolism. In the first part, we extended the study of brain control of glucose metabolism by investigating the central action of gastrin-releasing peptide (GRP), a neuropeptide synthesized in the SCN, on glucose metabolism. Our result indicates that central GRP induces long-lasting hyperglycemia. We also showed that acute sleep deprivation leads to impaired glucose tolerance. In the second part, we demonstrated that behavioural arousal induced by sleep deprivation or caffeine treatment enhances photic-entrainment of the SCN clock in the diurnal Sudanian grass rat, Arvicanthis ansorgei. These circadian responses in a diurnal species are opposite to the earlier findings in nocturnal rodents and may have biomedical applications

Abstract:
Social bonds are necessary for human survival and affectionate communication is paramount for their formation and maintenance. Consequently, affection deprivation -the condition of receiving less affectionate communication than desired-is associated with social pain, and contemporary research indicates that social pain has substantial neurological overlap with physical pain. Thus, it was proposed that affection deprivation would be associated with the sensation of physical pain as well as with poor-quality sleep. Three studies involving a total of 1,368 adults from nearly all U.S. states and several foreign countries revealed significant associations between affection deprivation, physical pain, and multiple facets of disturbed sleep.

Abstract:
Sleep is well-established to become more superficial and fragmented as we age, with deficits in cognitive processing also commonly observed. While effects have been identified in both humans and mice (used in this thesis), there are important species differences in these findings and importantly, very little is known about the neural dynamics underlying these changes. By integrating several state-of-the-art approaches from putative single unit electrophysiological recordings to behavioural and pharmacological assessments, this thesis aimed to provide novel insights into the neural mechanisms involved in the age-dependent changes in sleep and cognition in mice. Firstly, this thesis investigated the neural activity underpinning the known global sleep changes that occur with ageing. Surprisingly, the majority of neuronal measures quantified in this study were resilient to the effects of ageing. Therefore the global sleep disruptions identified with ageing are unlikely to arise from changes in local cortical activity. Secondly, diazepam injection was found to suppress neural activity, in addition to previously reported effects on electroencephalography (EEG). Subtle differences in the effects of diazepam were identified across age groups, which may account for the variability seen in the efficacy of benzodiazepines in older individuals. Thirdly, ageing and sleep deprivation were found to have only a few effects on performance in a spatial learning task, the Morris water maze (MWM). Suggesting that spatial learning may be fairly resilient to the effects of ageing and sleep deprivation. Finally, this thesis presents preliminary analyses that showed mice were able to perform two novel paradigms of the visual discrimination task, suggesting their suitability in studying the link between ageing, sleep and cognition. Together the studies presented in this thesis provide insights into the differences between global and local mechanisms affected by ageing. Only by understanding local mechanisms will we be able improve on current treatments aimed at helping with the unwanted effects of healthy ageing, such as cognitive decline and sleep disruptions.

Abstract:
Sleep deprivation has been studied for over a century, providing knowledge about the benefits of sleep for many physiological, cognitive, and behavioural functions. However, there have only been anecdotal indications about what a tired or sleep-deprived person looks like, despite the fact that appearance influences not only how other people perceive a person but also how they evaluate them and behave towards them. How someone with sleep loss is perceived and evaluated by others is the focus of this thesis. Facial photographs of 48 participants were taken after normal sleep and after either one night of total sleep deprivation or two nights of partial sleep deprivation. The photographs were then evaluated in four different studies by a total of 288 raters recruited from universities and the general public in Stockholm, Sweden. The faces were rated on attractiveness, health, tiredness, sleepiness, sociability, trustworthiness, employability, and leadership ability. These factors were all adversely affected by sleep loss. Furthermore, looking tired was strongly related to being less attractive, looking less healthy and less trustworthy, and being perceived as a poorer employee and leader. One of the studies assessed facial features commonly associated with looking tired, showing that sleep deprivation results in eyes which appear more swollen and red, with dark circles and hanging eyelids, as well as paler skin with more fine lines and wrinkles. When sleep deprived, people were also perceived as more sad. In conclusion, the four studies show that sleep loss and a tired appearance affect how one is perceived by other people. These perceptions may lead to negative evaluations in interpersonal situations, both personal and professional. This thesis thus demonstrates social benefits of prioritizing sleep, adding to the physiological, cognitive, and behavioural research on sleep loss.

Abstract:
The thesis describes investigations into two contrasting aspects of Slow Wave Sleep (SWS). The first is a laboratory based study of the effects of passive heating on the subsequent SWS of six healthy subjects, and the second employs home sleep recording techniques to investigate the prevalence and characteristics of the 'alpha sleep anomaly' in volunteers from the local community.

Abstract:
Why do we need to sleep? Not only is getting enough sleep important for our overall health and well-being, it is perhaps of utmost importance for normal brain functioning. Scientific findings derived from studying sleep deprivation suggests that sleep also plays an important role in our emotional functioning, which has led researchers to propose a causal and intimate relationship between sleep and emotional brain functioning. Without sleep it seems as our emotional processing become impaired in various ways. Along with advances in cognitive neuroscience, it is now possible to characterize mechanisms underlying emotional brain processes. In pursuit of the possible functions of sleep, researchers have also proposed that rapid eye movement sleep, might support a process of affective brain homeostasis and recalibration that optimally prepares the organism for next-day social and emotional functioning. This thesis reviews current behavioral and neurophysiological evidence focused on the relationship between sleep and emotional brain functioning, and the role of rapid eye movement sleep in emotional processing.
