Sex-Specific Effects Of Chaperone And Glial Defenses On Experimental Lewy Body Disease, 2022 Duquesne University
Sex-Specific Effects Of Chaperone And Glial Defenses On Experimental Lewy Body Disease, Tarun Bhatia
Electronic Theses and Dissertations
Lewy body disorders are a group of neurodegenerative conditions characterized by the pathological misfolding and aggregation of the abundant protein, α-synuclein. The most common Lewy body disorders are Parkinson’s disease and dementia with Lewy bodies. Apart from ageing, male sex is a major risk factor for Lewy body disorders, as men are at ~1.5-fold higher risk for these diseases than women. Yet, preclinical studies on Lewy body disorders rarely examine sex as a biological variable, and the mechanisms underlying sex-skewedness in disease risk remain undetermined.
Here, we developed a sex-stratified model of Lewy body disorders by exposing primary neurons harvested …
The Cognitive & Educational Implications Of Color Use In Drawing To Learn, 2022 William & Mary
The Cognitive & Educational Implications Of Color Use In Drawing To Learn, Juliana F.M. Cantarutti
Undergraduate Honors Theses
Drawing to Learn (D2L) is a learning aid that encourages STEM students to interact with abstract concepts in STEM by sketching. D2L is not an intuitive skill, and researchers strive to provide students with guidelines on how to master this method. One potential way to enhance the D2L method for students is by incorporation of visual cues, specifically color. While many students choose to incorporate color into their models without explicit instruction to do so, we have found no research on: a) why students use color in sketching, b) its effects on D2L. This study used interviews, surveys, and course …
Hdac6 Inhibition Reverses Long-Term Doxorubicin-Induced Cognitive Dysfunction By Restoring Microglia Homeostasis, 2022 The Texas Medical Center Library
Hdac6 Inhibition Reverses Long-Term Doxorubicin-Induced Cognitive Dysfunction By Restoring Microglia Homeostasis, Blake Mcalpin
Dissertations & Theses (Open Access)
One in 8 women in the US will be diagnosed with breast cancer. Currently, doxorubicin is one of the most effective chemotherapies for breast cancer. Unfortunately, up to 60% of survivors report long-term chemotherapy-induced cognitive dysfunction (CICD) characterized by deficits in working memory, processing speed, and executive functioning. Currently, no interventions for CICD have been approved by the US Food and Drug Administration. I show here that a 14-day treatment with a blood-brain barrier permeable histone deacetylase 6 (HDAC6) inhibitor successfully reverses long-term CICD following a therapeutic doxorubicin dosing schedule in female mice, as assessed by the puzzle box test …

Background: Previous work has examined the association of aggression levels and callous-unemotional traits with outcome expectations and values regarding the consequences of aggression. Less work has examined the outcome expectations and values regarding the consequences of aggression of adolescents with Conduct Disorder (CD). Also, no studies have examined links between irritability (a second socio-affective trait associated with CD) and these social cognitive processes despite the core function of anger in retaliatory aggression and establishing dominance.
Method: The current study, investigating these issues, involved 193 adolescents (typically developing [TD; N = 106], 87 cases with CD [N = 87]). Participants completed …

Department of Biology Faculty Scholarship and Creative Works
For more than two decades, research focusing on both clinical and non-clinical populations has suggested a key role for specific regions in the regulation of self-conscious emotions. It is speculated that both the expression and the interpretation of self-conscious emotions are critical in humans for action planning and response, communication, learning, parenting, and most social encounters. Empathy, Guilt, Jealousy, Shame, and Pride are all categorized as self-conscious emotions, all of which are crucial components to one’s sense of self. There has been an abundance of evidence pointing to the right Fronto-Temporal involvement in the integration of cognitive processes underlying the …
Strong Inferences About Pain In Invertebrates Require Stronger Evidence, 2022 University of Texas Health Science Center at Houston
Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters
Animal Sentience
Evidence for sentience in animals distantly related to humans is often sought in observations of behavioral and neural responses to noxious stimuli that would be painful in humans. Most proposed criteria for painful sentience in “lower” animals such as decapod crustaceans have no necessary links to the affective (“suffering”) component of pain. The best evidence for painful affect in animals is learned aversion to stimuli associated with noxious experience, and conditioned preference for contexts associated with relief from aversive consequences of noxious experience, as expressed in voluntary behavior. Such evidence is currently lacking for any invertebrate except octopus.
Characterizing And Investigating The Electrophysiological Properties Of The Plastic Cricket Auditory System In Response To Cooling, 2022 Bowdoin College
Characterizing And Investigating The Electrophysiological Properties Of The Plastic Cricket Auditory System In Response To Cooling, Hannah Tess Scotch
Honors Projects
The auditory system of the Mediterranean field cricket (Gryllus bimaculatus) is capable of profound compensatory plasticity. Following deafferentation due to the loss of an auditory organ, the dendrites of intermediate auditory neuron Ascending Neuron 2 (AN-2) grow across the midline and functionally connect to contralateral afferents. The loss of the auditory organ can be mimicked with reversible cold-deactivation, in which cooled Peltier elements silence the auditory organ and its afferents. Though this would presumably prevent AN-2 from firing, cooling instead induces a novel firing pattern called DOPE (delayed-onset, prolonged-excitation). In this study, intracellular physiological recordings were completed before, …
Making The Invisible Visible: Mapping Chronic Pain Through Art, 2022 Claremont Colleges
Making The Invisible Visible: Mapping Chronic Pain Through Art, Caroline Young
Scripps Senior Theses
This Studio Art thesis explores how I use my art practice as a chronic pain healing process. It draws on the fundamentals of the neuroscience behind pain and the implications of this science for people with chronic pain. People with chronic pain often turn to alternative healing techniques in their search for relief; my own alternative healing approach comes from my art practice of “pain mapping."
The artistic healing process that I have developed takes inspiration from chronically ill artists such as Frida Kahlo and Anna Cowley Ford. The artistic mapping of my pain that I have developed primarily uses …
The Effects Of Venlafaxine And Voluntary Exercise On Chronic Unpredictable Stress Induced Anxiety, 2022 The College of Wooster
The Effects Of Venlafaxine And Voluntary Exercise On Chronic Unpredictable Stress Induced Anxiety, Marly Mcgowan
Senior Independent Study Theses
Anxiety disorders can impair cognition and emotional control, particularly in the face of novel situations, which is concerning due to the high prevalence of such diagnoses. Exposure to unpredictable chronic stress can provide a way to induce anxiety-like behaviors in rodents by disrupting the stress response systems, including the HPA axis and autonomic nervous system. Pharmacological treatments, including SNRIs like venlafaxine, and voluntary exercise are both anxiolytic treatments that can alleviate the impacts of chronic stress. Using unpredictable chronic stress to mimic the human condition, and exposure to venlafaxine and exercise to mitigate the stress, the open field and elevated …
Potential And Limitations Of Using Stem Cells To Cure Alzheimer’S Disease: A Literature Review Of Its Potential And Ethical Limitations In Translation To Human Trials, 2022 Old Dominion University
Potential And Limitations Of Using Stem Cells To Cure Alzheimer’S Disease: A Literature Review Of Its Potential And Ethical Limitations In Translation To Human Trials, Eleni Zivla
OUR Journal: ODU Undergraduate Research Journal
Alzheimer's disease has become one of the most significant, life-limiting illnesses of our time as a result of the rapid increase in the average life expectancy. To successfully develop a cure for this yet incurable disease, one must understand the pathology of Alzheimer’s disease. As found in recent research studies, a brain that is diagnosed with Alzheimer's is characterized by the presence of extracellular amyloid plaques composed of the amyloid-beta (Aβ) peptide and intracellular neurofibrillary tangles composed of the microtubule-associated protein: tau. In this literature review, several stem cell therapies are being reviewed as a potential cure for Alzheimer’s disease …
Mechanistic Insight Into Chronic Stress-Induced Cerebrovascular Dysfunction, 2022 West Virginia University
Mechanistic Insight Into Chronic Stress-Induced Cerebrovascular Dysfunction, Emily Nicole Burrage
Graduate Theses, Dissertations, and Problem Reports
Despite decades of research psychological stress remains a prevalent problem in society, often diminishing quality of life and increasing the risk of developing dementia. The brain plays a central role in the response to stress and as it is unable to store energy substrates, the brain relies heavily on dynamically regulated blood flow. Therefore, it is important that there is a tight coupling between neural activity and cerebral blood flow to meet metabolic demands and maintain critical brain function. It has been established that chronic psychological stress has detrimental effects on cerebrovascular function, potentially through increased superoxide anion production through …

The human ability to adaptively implement a wide variety of tasks is thought to emerge from the dynamic transformation of cognitive information. We hypothesized that these transformations are implemented via conjunctive activations in “conjunction hubs”—brain regions that selectively integrate sensory, cognitive, and motor activations. We used recent advances in using functional connectivity to map the flow of activity between brain regions to construct a task-performing neural network model from fMRI data during a cognitive control task. We verified the importance of conjunction hubs in cognitive computations by simulating neural activity flow over this empirically-estimated functional connectivity model. These empiricallyspecified simulations …
Affective Flexibility As A Developmental Building Block Of Cognitive Reappraisal: An Fmri Study, 2022 University of Nebraska-Lincoln

Center for Brain, Biology, and Behavior: Faculty and Staff Publications
Cognitive reappraisal is a form of emotion regulation that involves reinterpreting the meaning of a stimulus, often to downregulate one’s negative affect. Reappraisal typically recruits distributed regions of prefrontal and parietal cortex to generate new appraisals and downregulate the emotional response in the amygdala. In the current study, we compared reappraisal ability in an fMRI task with affective flexibility in a sample of children and adolescents (ages 6–17, N = 76). Affective flexibility was defined as variability in valence interpretations of ambiguous (surprised) facial expressions from a second behavioral task. Results demonstrated that age and affective flexibility predicted reappraisal ability, …
Physiological Effects Of Activity-Based Anorexia In Female Rats And An Overview Of Eating Disorders, 2022 Regis University
Physiological Effects Of Activity-Based Anorexia In Female Rats And An Overview Of Eating Disorders, Madelyn Uyemura
Regis University Student Publications (comprehensive collection)
The aim of this thesis is to bring AN to the foreground of conversation both in a scientific and sociological framework. Nearly 40 million Americans suffer from anxiety disorders, which is characterized by the feeling of a loss of control. In some cases, another disorder called anorexia nervosa (AN) can codevelop. AN is characterized by a refusal, and inability, to maintain a healthy body weight. Some suffering from anxiety may restrict caloric intake and increase exercise to cope with stress. This results in extreme caloric deprivation. AN can be modeled in rats using an activity-based anorexia (ABA) method. In …
Integrating Interpersonal Neurobiology In Healthcare Leadership And Organizations, 2022 Antioch University - PhD Program in Leadership and Change
Integrating Interpersonal Neurobiology In Healthcare Leadership And Organizations, Lynn Redenbach
Antioch University Full-Text Dissertations & Theses
Interpersonal Neurobiology (IPNB) is an interdisciplinary, science-based field that seeks to understand human reality including the nature of mind, brain, and relationships. IPNB has been used extensively by mental health practitioners as well as child development and parenting experts. While practitioners and scholars have described ways that IPNB can be used in leadership and organizations, there has been no systematic inquiry into the practical and phenomenological experience of this application. IPNB offers an alternative to dominant models of care and leading in healthcare settings and fields, which are characterized by disconnection, objectification, and separation. It offers a relationally centered approach …
Investigating The Effects Of In-Vivo Therapeutics Hypoxia Treatment Paradigms In Neurite Outgrowth Patterns, 2022 University of Kentucky
Investigating The Effects Of In-Vivo Therapeutics Hypoxia Treatment Paradigms In Neurite Outgrowth Patterns, Jae Hyun Yoo
Theses and Dissertations--Medical Sciences
Spinal cord injury, specifically in the cervical C3-C4 region of the cervical spine, contributes to impaired breathing and a diminished quality of life. Therefore it is important to find effective and safe therapeutics to restore breathing function. Indeed, there are a myriad of research being performed in addition to valuable collaboration amongst different institutions. As such, inspired by a previous experiment, we decided to test our hypothesis that an enriching environment consisting of different hypoxic environments - sustained and intermittent hypoxia alongside normoxia - would result in neurite outgrowth. Moreover, we hypothesized that sustained hypoxia would result in the greatest …

Pharmaceutical Sciences and Research
Treatment of diabetic neuropathy is still carried out by providing symptomatic therapy, which only improves ± 50% of the total symptoms felt by patients, but does not tackle the underlying causes of the disease. Astaxanthin is a potent antioxidant, anti-inflammatory, and anti-diabetic carotenoid that could be an additional treatment option. We aimed to measure the effectiveness of administering astaxanthin as an additional therapy to improve the impact of pain and discomfort experienced daily by diabetes mellitus patients with painful diabetic neuropathy. We conducted a randomized experimental study with an open label design of 36 patients who had been diagnosed with …
