Dysregulation of sleep and metabolism has enormous health consequences. Sleep loss is linked to increased appetite and insulin insensitivity, and epidemiological studies link chronic sleep deprivation to obesity-related disorders. Interactions between sleep and metabolism involve the integration of signalling from brain regions regulating sleep, feeding, and metabolism, as well as communication between the brain and peripheral organs.

Show moreDysregulation of sleep and metabolism has enormous health consequences. Sleep loss is linked to increased appetite and insulin insensitivity, and epidemiological studies link chronic sleep deprivation to obesity-related disorders. Interactions between sleep and metabolism involve the integration of signalling from brain regions regulating sleep, feeding, and metabolism, as well as communication between the brain and peripheral organs. In this series of studies, using the fruit fly as a model organism, we investigated how feeding information is processed to regulate sleep, and how peripheral tissues regulate sleep through the modulation of energy stores. In order to address these questions, we performed a large RNAi screen to identify novel genetic regulators of sleep and metabolism. We found that, the mRNA/DNA binding protein, Translin (trsn), is necessary for the acute modulation of sleep in accordance with feeding state. Flies mutant for trsn or selective knockdown of trsn in Leucokinin (Lk) neurons abolishes starvation-induced sleep suppression. In addition, genetic silencing of Lk neurons or a mutation in the Lk locus also disrupts the integration between sleep and metabolism, suggesting that Lk neurons are active during starvation. We confirmed this hypothesis by measuring baseline activity during fed and starved states. We found that LHLK neurons, which have axonal projections to sleep and metabolic centers of the brain, are more active during starvation. These findings suggest that LHLK neurons are modulated in accordance with feeding state to regulate sleep. Finally, to address how peripheral tissues regulate sleep, we performed an RNAi screen, selectively knocking down genes in the fat body. We found that knockdown of Phosphoribosylformylglycinamidine synthase (Ade2), a highly conserved gene involved the biosynthesis of purines, regulates sleep and energy stores. Flies heterozygous for two Ade2 mutations are short sleepers and this effect is partially rescued by restoring Ade2 to the fly fat body. These findings suggest Ade2 functions within the fat body to promote both sleep and energy storage, providing a functional link between these processes. Together, the experimental evidence presented here provides an initial model for how the peripheral tissues communicate to the brain to modulate sleep in accordance with metabolic state.

Show moreAccumulating evidence points to a fundamental connection between sleep and feeding behavior. However, the temporal, genetic, and neuronal architecture that defines these relationships is poorly understood. Drosophila are amenable to high-throughput studies and offer numerous genetic tools which have advanced our understanding of the mechanistic relationships between these behaviors. However, certain features of the sleep-feeding axis have remained elusive, largely due to the separate measurement of sleep and feeding. Here, I develop a system which simultaneously measures sleep and feeding in individual animals by employing high resolution machine vision tracking and micro-controller interface functionality. Using this system, I show that food consumption drives a transient rise in sleep, which depends on food quality, quantity, and timing of a meal. The leucokinin system mediates these effects, particularly in response to protein ingestion. We further use the system to examine sleep homeostasis and demonstrate sleep dependence on energy expenditure and fat-brain communication. Collectively, these findings provide novel insight into the fundamental connections between sleep and feeding behavior.

Show moreSparse thalamocortical cell population synchronicity during sleep spindle oscillations has been hypothesized to promote the integration of hippocampal memory information into associated neocortical representations 1. We asked the question of whether sparse or rhythmic activity in thalamocortical cells of the reuniens nucleus influence memory consolidation and cognitive flexibility during learning after sleep. For this study, I designed a novel attentional set-shifting task and incorporated optogenetics with closed-loop stimulation in sleeping rats to investigate the effects of sparse (nonrhythmic) or rhythmic spindle-like (~10Hz) activity in thalamic cells of the reuniens nucleus on learning and cognitive flexibility. We show that, as predicted, post-sleep setshifting performance improved after sleep with non-rhythmic optogenetic stimulation in the thalamic nucleus reuniens relative to rhythmic optogenetic stimulation. While both non-rhythmic and rhythmic optogenetic stimulation led to an increase in perseverative errors, only non-rhythmic optogenetic stimulation showed effects of learning from errors, which correlated with sleep, and which ultimately had a net benefit in set-shifting performance compared to rhythmic optogenetic stimulation and the control group.

Show moreProper regulation of sleep and metabolism are critical to the survival of all organisms. In humans, dysregulation of sleep is linked to metabolic syndrome, including hypertension, hyperglycemia and hyperlipidemia. However, the mechanisms regulating interactions between sleep and metabolism are poorly understood. Although the fruit fly, Drosophila melanogaster, bears little anatomical resemblance to humans, it shares similar genetics essential in understanding normal development and disease in humans. From humans to flies, many disease-related genes and pathways are highly conserved, rendering the fruit fly ideal to understanding the interactions between sleep and metabolism. Therefore, using the fruit fly provides a framework for understanding how genes function between sleep and metabolism. During starvation, both humans and rats reduce their sleep. Similarly, previous studies have shown that fruit flies also suppress sleep to forage for food, further showing that sleep and metabolism are intricately tied to one another and that they are highly conserved across species. To further explore the interactions between sleep and metabolism, I have conducted multiple genetic screens to identify novel regulators of sleep-metabolism interactions. These experiments led to the identification of the mRNA binding protein translin (trsn) as being required for starvation-induced sleep suppression. A second screen that targeted metabolic genes from a genome-wide association study identified the ion channel accessory protein uncoordinated 79 (unc79) as a critical regulator of both sleep duration and starvation resistance. The genes function in different regions of the brain and suggest complex neural circuitry is likely to underlie regulation of sleep metabolism interactions. Taken together, a mechanistic understanding of how different genes function to regulate sleep in flies will further our understanding of how sleep and metabolism is regulated in humans.

A hypothesized model of spindle organization of thalamic and hippocampal spike dynamics (Figure 1) suggests that sparsity operates in spindles as an essential component of thalamic activity that could be contributing to flexibility in learning (Varela & Wilson, 2020).

Show moreA hypothesized model of spindle organization of thalamic and hippocampal spike dynamics (Figure 1) suggests that sparsity operates in spindles as an essential component of thalamic activity that could be contributing to flexibility in learning (Varela & Wilson, 2020). We asked the question of whether sparse spindle-like (10Hz non-rhythmic) or 10Hz rhythmic activity in thalamic cells of the reuniens nucleus influence cognitive flexibility during learning after sleep. By comparing the two stimulation protocols (“nonrhythmic” and “rhythmic”), we tested if disrupting the characteristic sparsity reveals any changes in flexibility during learning after sleep. Results showed that sleep accompanied 10Hz rhythmic optogenetic stimulation of thalamic nucleus reuniens impaired rule-switching (or set-shifting) performance and disrupted the sleep enhancing rule-switch associated increase in vicarious trial and error (VTE), which we used as a metric for deliberation. We found that rule-switching was associated with a subsequent increase in VTE, as were incorrect choices, and when rats subsequently made correct choices. Instead, stimulating against the endogenous thalamocortical spindle oscillation (i.e. sleep accompanied 10Hz rhythmic optogenetic stimulation) resulted in a significant disruption in post-sleep performance and VTE during, but not prior to, rule-switching. Lastly, optogenetic 10Hz stimulation of the thalamic nucleus reuniens did not affect sleeping or waking behavior during the sleep box session but it did show a clear though nonsignificant increase in waking head velocities; thus, changes in cognitive flexibility and VTE cannot be explained by any changes in sleep itself, but rather due to the after-effects the specific patterns of 10Hz optogenetic stimulation in thalamic nucleus reuniens applied during sleep had on cognition.

Show moreOut of 60 million Americans suffering from sleep disorder, an estimated 18 million have sleep apnea. According to the U.S. Department of Health & Human Services, sleep apnea is a chronic condition that disrupts a patient’s sleep. While the annual cost of treating sleep apnea patients in the United States is approximately $3.18 billion (including screening costs) it is estimated that untreated sleep apnea may cause $3.4 billion in additional medical costs. A polysomnography (PSG) is an all-night sleep study which monitors various physical functions during sleep including electrical activity of the heart, brain wave patterns, eye movement, muscle tone, body movements, and breathing. It is currently, the most accurate and sophisticated test for the diagnosis of sleep-disordered breathing (SDB), but also, the most expensive. The cost of an overnight sleep study is estimated between $900 and $3,000. In addition, the PSG is not mobile and has to be administered outside a patient’s home. The Long QT Syndrome (LQTS) is a rhythm disorder that causes erratic (unpredictable) heartbeats. The LQTS has been linked to patients with the most severe form of sleep apnea. If LQTS is left untreated, sudden cardiac death may occur.

Show moreRapid Eye Movement (REM) sleep in adult and neonatal mammals is characterized by episodes of high variability and bursting in brainstem sites associated with spontaneous tonic and phasic behavioral events such as REMs, nuchal inactivity and twitches of the body. REM sleep is the principal behavioral state during fetal and neonatal life and as has been demonstrated by various REM deprivation procedures to be indispensable during this period and to lead to long lasting behavioral defects in adult life. The guiding hypothesis throughout this dissertation is that the variability of REM-associated nuchal atonia episodes and other spontaneous motor events reflects the fractal time patterns of a global fetal REM sleep state over multiple timescales serving as a transient behavioral ontogenetic adaptation to changing developmental environments. Further, spontaneous activity over many levels of organization, including phasic REM motor activity during ontogeny, could play a fundamental role in the development of appetitive behavioral processes (e.g., searching and orienting) and other forms of neuroplasticity (e.g., learning and dynamic regulation of receptor fields and maps). The nature of this variability was investigated by measuring the durations of nuchal atonia over extended periods in fetal sheep and neonatal rats, species which are in a REM sleep-like state >50% of the time. Hurst's rescaled range analysis, which affords comparisons between natural time series with short- and long-term correlated fluctuations, indicated that variability in both species over short time scales is statistically similar to longer time scales (i.e., is fractal in time) and remarkably stable over the developmental periods examined. Spontaneous nuchal events in both species were also found to be described by convolutionally stable self-similar Levy distributions, suggesting that activity associated with fetal REM sleep could provide a stable, scale invariant source of correlated stimulation, facilitating integration of new neural changes into developing motor and cortical networks over gestation. These fractal time descriptions of spontaneous prenatal behaviors have implications for conceptualizing the evolutionary mechanisms underlying heterochrony (shifting self-affine relationships between the timing of gene expression and behavioral activity) and the plasticity essential to the genesis of behavioral neophenotypes.

Show moreThe purpose of this research was to identify the impact of students’ choice of time of day for class activity and their sleep quality on academic performance in multidisciplinary distance education courses at a southeastern U.S. state college. The research addressed the relationship of other individual student characteristics (i.e., age, gender, race/ethnicity, educational background, or course workload) and external factors (i.e., marital status, hours of employment, part-time or full-time status, or caretaker responsibilities represented by the number of children and/or elderly that the student was actively caring for in their home) to the students’ academic performance and to the students’ choice of time of day for class activity and sleep quality. This study analyzed distance education students’ Pittsburgh Sleep Quality Index (PSQI) Global Sleep Quality Scores, their demographic and external factor survey responses, a test grade, and the time of day that the student submitted their test. This study targeted the distance education student population, as they are part of a rapidly growing sector within higher education, and they had previously not served as the primary subjects in research regarding sleep quality and external factor impacts on academic success. Analyses of 208 distance education students resulted in the following research findings: sleep quality was found to be related to academic success, with significant findings of, for example, poorer sleep quality correlating with a lower test grade (r = -0.15; p = .03), likewise the number of hours spent working was related to academic success, with a significant finding of more hours spent working correlating with a lower grade (r = 0.377; p = .008). In this study most other factors were found to have no significant relationship with a students’ grades (age, gender, race/ethnicity, educational background, or course workload, marital status, or caretaker responsibilities). These research findings may enlighten students of the potential impacts of taking distance education classes if they anticipate having to work extensively or if they have, or expect to have, poor sleep quality. Additionally, educational institutions and faculty can learn ways to design better distance education courses and provide improved guidance for students to encourage academic success.

Sleep is conserved across evolution, though significant variations in sleep duration, architecture, and behavior are found across phyla. Decoding neural processing underlying behavior, including sleep, is a fundamental aim in neuroscience, and understanding how such behavior has evolved remains largely unknown. The encompassing goal of this dissertation is to elucidate the genetic and neuronal factors at play in the evolution of sleep loss in the blind Mexican tetra, Astyanax mexicanus. To this end, the work found within will explore peripheral sensory systems regulating distinct mechanisms of sleep loss, demonstrate how evolved changes in specific hypothalamic circuits drive sleep reductions, apply computational techniques to understand whole-brain evolution, and finally, will show how the generation of transgenic tools in a novel model system can be harnessed to assist functional experimental paradigms in relation to evolution and behavior.

Show moreOne in three American older adults fall every year, making falls the leading cause of nonfatal injury treated in the emergency department (Centers for Disease Control and Prevention [CDC], 2013). Fall-related injuries cost the United States healthcare system nearly $30 billion a year and result in 27,000 deaths per year (Burns, Stevens, & Lee, 2016). The risk of falls increases with age, occurring more often in women than man. Age-related muscle weakness and functional decline contribute to fall risk. Age-related changes in neuroendocrine hormone production and shifts in circadian rhythms promote sleep disorders, affecting nearly two-thirds of older adults. Poor sleep quality over time leads to drowsiness and impaired attention span and judgment. The purpose of this secondary analysis of a previously collected data set was to describe the relationships among frailty, subjective sleep quality, and falls in community-dwelling older adults. This secondary analysis also sought to determine the extent to which frailty and subjective sleep quality predict risk of future falls among community-dwelling older adults. Correlational analyses were performed to determine the nature and significance of the relationship between sleep quality and falls, frailty and falls, and sleep quality and frailty. A multiple regression analysis was performed to determine if sleep quality and frailty combined could predict falls. Frailty was found to account for a small variance in fall risk. However, sleep quality was not significantly related to falls nor was sleep quality predictive of falls. Risk for falls should be assessed at every clinical encounter and efforts to promote restful sleep should be addressed at least annually to reduce the risks of falls, functional decline, and sleep disorders among older adults in the community.

Both contemporary authors suggest that certain negative aspects inherent in the Sleeping Beauty paradigm should not persist in women's literature, unless the texts lead to transformation and self-realization of the heroines. This study demonstrates how the authors expose the fallacy in the paradigm, depart from it, and refigure it by transforming their heroines into characters quite distinct from the Grimm prototype. This study also suggests that Ferre's and Atwood's works serve as prototypes for feminine texts. As the characters distance themselves from hegemonic patriarchal traditions, each author's work is also removed from the referent of masculine literary traditions and returned to its origins, the oral tale.
