Defining The Peripheral Plasticity Of Nociceptive Afferents Following Spinal Cord Injury And Physical Therapy Intervention., Morgan Julianna Forston
Electronic Theses and Dissertations
The focus of this dissertation is to explore the peripheral plasticity of nociceptive afferents following spinal cord injury (SCI) and whether it is exacerbated or induced when physical therapy-based muscle stretching, a therapy we have shown to be detrimental to locomotor recovery in rodents, is implemented post-SCI. Chapter I provides a brief introduction on sensory afferents with particular emphasis on nociceptive afferents and their multifaceted role within the peripheral and central nervous systems. Chapter II describes SCI epidemiology and common sensory related complications that occur in patients as well and pharmaco- and physical therapies that are employed post-SCI. Chapter III …

Introduction: We are currently facing an aging crisis, as 20% of the U.S. population will be geriatric (65+) by 2030. This growing geriatric population will result in increasing prevalence of age-related diseases, coinciding with increasingly prevalent environmental pollution. Environmental pollution is a ubiquitous health threat that affects people at all ages and contributes to aging pathology. However, geriatric individuals are likely more susceptible to the negative health effects from environmental pollution. The distinct effects of environmental pollutants across age groups are currently understudied. We use a Toxic Aging Coin approach to investigate: 1) how age impacts toxicity (heads), …
Establishing A Mouse Model Of Cerebral/Cortical Visual Impairment., Dana K. Oakes
Establishing A Mouse Model Of Cerebral/Cortical Visual Impairment., Dana K. Oakes
Electronic Theses and Dissertations
Cerebral/cortical visual impairment (CVI) is a disorder most often caused by perinatal hypoxic injury to the developing brain. CVI is the leading cause of childhood visual impairment in developed nations, encompassing deficits in many aspects of vision including visual acuity, contrast sensitivity, and object recognition. The pathophysiology of CVI is not well understood because no animal model currently exists to study this disorder. Because there is no animal model, the pathophysiology of CVI is poorly understood. Here, we developed a murine early postnatal hypoxic model of CVI by exposing mice to 9.5% O2 at postnatal day (P)3 for a …

Individuals with spinal cord injury (SCI) are susceptible to the misuse of opioids due to the introduction of these substances for pain management. There are very few studies examining the relationship between unintentional deaths caused by opioid usage following spinal cord injury. The objective of this study was to evaluate the trend of opioid-related mortality of individuals with spinal cord injury (SCI) over the years and compare these findings to the mortality rates due to opioid misuse in the general population. In this study, we used data provided by the National Spinal Cord Injury Model Systems (NSCIMS) for SCI 1999-2016 …
Novel Insights Into Oligodendrocyte Biology From Developmental Myelination Studies In Autophagy Deficient Mice And Analysis Of Oligodendrocyte Translatome Response To Contusive Spinal Cord Injury., Michael David Forston
Novel Insights Into Oligodendrocyte Biology From Developmental Myelination Studies In Autophagy Deficient Mice And Analysis Of Oligodendrocyte Translatome Response To Contusive Spinal Cord Injury., Michael David Forston
Electronic Theses and Dissertations
Loss of myelin causes severe neurological disorders and functional deficits in white matter injuries (WMI) such as traumatic spinal cord injury (SCI). This dissertation is focused on autophagy in OL development and the OL translatome after SCI. Chapter I describes the history of myelin, OL development, and their involvement in neurodegenerative diseases and SCI. The proteostasis network, in particular autophagy, and its contributions to white matter pathology is discussed. It concludes examining advantages and disadvantages of unbiased omics tools, like RiboTag, to study transcriptional/translational landscapes after SCI. Chapter II focuses on autophagy in OPC/OL differentiation, survival, and proper myelination in …
Immobilization And Its Effects On Functional Recovery After Spinal Cord Injury., William H. Gregory
Immobilization And Its Effects On Functional Recovery After Spinal Cord Injury., William H. Gregory
College of Arts & Sciences Senior Theses
Recovery, or rather the failure to recover, is a perplexing issue of spinal cord injury that is currently being investigated. This issue becomes more puzzling when investigating models in which spinal cord injury (SCI) is studied. There appears to be greater functional recovery experienced by animals within these models after injury as compared to patients in the clinical setting. While many things could contribute to this disparity, one difference that stands out when comparing the basic research model and clinical experience of SCI is the inactivity and limb disuse after the injury. This same level of immobility is rarely accounted …
Effect Of Dorsal Quadrant Or Ventral Quadrant Spinal Cord Injury On Gait Features During Locomotion., Anya Nicole Trell
Effect Of Dorsal Quadrant Or Ventral Quadrant Spinal Cord Injury On Gait Features During Locomotion., Anya Nicole Trell
Electronic Theses and Dissertations
In the Unites States, approximately 1.5 million people currently have a spinal cord injury and suffer permanent sensory and motor loss due to the disruption of the spinal cord. Due to the significant morbidity, it is vital to understand the functional impact of disrupting neural descending pathways that modulate spinal neurons involved in intermuscular coordination critical for gait behaviors. Tasks that are more difficult require additional input from these neural pathways; therefore, fourteen feline subjects were familiarized with level overground locomotion and stair descent gait tasks. After collection of baseline kinematic data, the subjects received either a dorsal or ventral …
Investigations Of Potential Mechanisms Underlying Spinal Cord Injury-Induced Polyuria., Jason H. Gumbel
Investigations Of Potential Mechanisms Underlying Spinal Cord Injury-Induced Polyuria., Jason H. Gumbel
Electronic Theses and Dissertations
Spinal cord injury (SCI) results in neurological impairments including motor, sensory, and autonomic dysfunction. These neurological deficits result in a litany of complications apart from muscular paralysis, including bladder, bowel, cardiovascular, and sexual function. SCI-induced polyuria (the overproduction/passage of urine) remains understudied, and therefore mechanisms behind it are largely unknown and require extensive investigation for potential targeted therapies to improve quality of life. The objective of this dissertation was to investigate potential mechanisms of SCI-induced polyuria and explore potential therapies to improve quality of life in the SCI population. Metabolic cages, Western blot, enzyme-linked immunoassay, and immunostaining were first used …
Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar
Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar
Journal of Wellness
The essential question of the relationship between consciousness and matter is ignored in medical school curricula, leading to a machine-like view of the human being that contributes to physician burnout and intellectual dissatisfaction. The evidence suggesting that the brain may not be the seat of consciousness is generally ignored to preserve the worldview of the primacy of matter. By investigating new frameworks detailing the nature of consciousness at different levels of hierarchy, we can bring intellectual rigor to a once opaque subject that supports a fundamental reality about our experience: We are human beings, not only human bodies.
Glycine Receptor Expression Across Identified Retinal Ganglion Cell Types., Ian Scot Pyle
Glycine Receptor Expression Across Identified Retinal Ganglion Cell Types., Ian Scot Pyle
Electronic Theses and Dissertations
Retinal ganglion cells (RGCs) represent the culmination of all retinal signaling and their output forms the substrate for vision throughout the rest of the brain. About 40 different RGC types have been defined by differences in their visually evoked responses, morphology, and genetic makeup. These responses arise from interactions between inhibition and excitation throughout the retinal circuit (Franke et al., 2017; Masland, 2012; Sanes & Masland, 2015; Werblin, 2011). Unlike most other areas of the central nervous system (CNS), the retina utilizes both GABA and glycine inhibitory neurotransmitters to refine glutamatergic excitatory signals (Franke & Baden, 2017; Werblin, 2011; C. …

Circuits For Active Vision : Parallel Tectothalamocortical Visual Pathways In The Mouse., Na Zhou
Electronic Theses and Dissertations
Vision is a critical sensation for the interaction between humans and their surrounding environment. The eyes connect with the brain via retinal ganglion cell axons, which transmit visual sensory information from the periphery into the central nervous system for further processing, eventually leading to visual perception and the visual guidance of movement. Two main targets of retinal axons are the superior colliculus (SC) and the dorsal thalamus. From the SC, visual information is conveyed to the dorsal thalamus, and from the dorsal thalamus visual information is conveyed to the cortex, striatum and amygdala. This dissertation is focused on the functional …
