Effects Of Hyperglycemia In Cognition And Sex, Erin E. Mcdonald Apr 2025

Effects Of Hyperglycemia In Cognition And Sex, Erin E. Mcdonald

Senior Honors Theses

An empirical study tested the effects of Type 1 Diabetes (T1D) on cognitive function in a hyperglycemic mouse model. Strong correlations between mental illnesses, such as major depressive disorder, neuropathologies like Alzheimer’s disease, and diabetes suggest comorbid pathology. Considering the prevalence of both T1D and cognitive decline within the general population, the findings were relevant and aimed to identify early signs of cognitive decline in diabetic patients. Behavioral tests and immunohistochemical staining were utilized to determine the cognitive function of the mice, revealing decline or deterioration caused by hyperglycemia. Data gathered from the hyperglycemic or control mice were analyzed based …

Faculty mentor: Dr. Andra Geana, Psychology and Neuroscience

Reinforcement learning (RL) mathematically describes how agents learn to maximize the reward of their environment by understanding and comparing their choice options. This project investigates how anxiety and compulsivity impact the selection of these options and to what extent a text-based, narrative (rather than a game-like environment) changes RL processes in humans.


Not Human Enough: The Origins Of The Uncanny Valley, Franklin Young Apr 2025

Not Human Enough: The Origins Of The Uncanny Valley, Franklin Young

Osmosis Magazine

Why do we feel creeped out when we see something almost human—like a lifelike robot or a bad CGI character? This phenomenon, known as the uncanny valley, describes the uncomfortable emotional response humans experience when encountering entities that appear nearly, but not quite, human. First introduced by Japanese robotics professor Masahiro Mori in 1970, the concept suggests that as objects become more humanlike in appearance, our emotional response to them becomes increasingly positive —until reaching a point where subtle imperfections trigger strong feelings of revulsion.

The Effect Of Lithium On Intracellular Myo-Inositol Levels In Human Lymphoblasts Of Bipolar Disorder Patients, Ntakirutimana Francine

Honors Theses

Bipolar disorder is a chronic disorder characterized by mood swings of mania and depression. Bipolar I is characterized by intense mania, while bipolar II is characterized by hypomania and depression. Currently, there is no cure for bipolar disorder; however, one mainstay of treatment is lithium, which is hypothesized to alleviate symptoms by reducing myo-inositol.

In this study, the effect of lithium on intracellular myo-inositol was determined in lymphoblasts derived from bipolar disorder patients and compared to that of lymphoblasts from a neurotypical individual. At 1mM lithium, the data showed increased myo-inositol levels across cell lines; however, the results were not …

The Effects Of Stress On Injury And Sickness Rates Of Middle-Distance And Distance D3 Athletes, Hailey D. Smith Ms.

Student Scholar Showcase

A runner intentionally stresses their body to experience an adaptation, however, issues occur when the body does not have time to recover. Male athletes (n = 14) on the University of Lynchburg’s distance and middle-distance team participated in this study. For 6 weeks, heart rate variability (HRV4training app), resting heart rate, perceived stress, and cortisol levels were assessed as indicators of recovery and stress. It was anticipated that indicators of physical stress such as higher resting heart rates and higher cortisol levels, would correspond with greater perceived stress and higher occurrence of injury and sickness. Cortisol (n = 2, p …

Perfectionism, Anxiety, And Depression: A Comparison Of Student Mental Health At East Texas A&M University: Honors Vs Non-Honors, Connor Hall

Honors Theses

Honors students at East Texas A&M University (ETAMU) may have higher expectations to succeed due to greater course load and pressure versus students who are not in the honors program. These expectations can lead to stress that may cause perfectionism, anxiety, or depression (Rice, 2006; Wan, 2022; Van Praag, 2004). This study sought to determine if higher expectations and course load could lead to differences in mental health in honors versus non-honors students at East Texas A&M University. In order to determine these mental health characteristics, data was gathered using responses to a Qualtrics survey sent to 7527 ETAMU undergraduate …


The Implications Of The Scientific Developments Behind Oxidative Stress, Heat-Shock Proteins, And Antioxidants On Neurodegenerative Pathology, Nolan Wilbourn Apr 2025

The Implications Of The Scientific Developments Behind Oxidative Stress, Heat-Shock Proteins, And Antioxidants On Neurodegenerative Pathology, Nolan Wilbourn

Honors Theses

Homeostasis is essential for the health and development of all organisms, serving as a universal defense mechanism that ensures the stability of physiological processes faced with external and internal stimuli in the form of health challenges (Archana et al., 2017). Maintaining homeostasis is crucial for our health, as it helps keep the body's internal balance. However, this delicate equilibrium is challenged by various environmental factors, such as diet, exposure to chemicals, and fluctuations in temperature (Collier et al., 2017). These disruptions can lead to dysfunction in cellular processes, particularly affecting the production and regulation of proteins vital for biological functions. …

The central hypothesis was that the stroboscopic vision training would enhance softball vision performance. The central hypothesis was tested using these specific aims: 1) batting statistics for a year with no …


Psilocybin Impairs The Extinction Of Contextual Fear In Adult Female, But Not Male, Rats, Lillianna P. Puppel, Aleece K. Al-Olimat, Kylie M. King, Marisa J. Savini, Claire E. Miller, Colin R. Del Valle, Heather R. Sparkman, Brooke E. Bramlage, Phillip R. Zoladz Apr 2025

Psilocybin Impairs The Extinction Of Contextual Fear In Adult Female, But Not Male, Rats, Lillianna P. Puppel, Aleece K. Al-Olimat, Kylie M. King, Marisa J. Savini, Claire E. Miller, Colin R. Del Valle, Heather R. Sparkman, Brooke E. Bramlage, Phillip R. Zoladz

ONU Student Research Colloquium

Fear-related disorders are often treated with exposure therapy, a technique based on the concept of extinction. However, this type of therapy is ineffective for many individuals, so finding a pharmacological adjunct that augments the extinction of fear could lead to better treatment outcomes. In recent preclinical work, investigators have shown that psychedelics can accelerate the extinction of fear, potentially through their impact on neurotrophic signaling. We previously found that psilocybin exerted sex-dependent effects on the extinction of conditioned fear to an isolated cue (i.e., a tone). Specifically, psilocybin enhanced the extinction of cue fear in male rats but impaired it …

The Role Of Urbanization And Corticosterone In Auditory Sensory Processing In House Sparrows (Passer Domesticus), Brooke Fox, Ashley Lauraine, Hannah Peterson

24th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2025)

Urban habitat expansion will introduce new anthropogenic challenges for wildlife populations, including habitat fragmentation, novel predators, and pollution. These challenges may hinder animal communication and contribute to increased stress levels. This study will investigate the physiological consequences of stressors on the house sparrow (Passer domesticus). Specifically, we will examine how urbanization affects stress hormone (i.e., corticosterone, CORT) levels and its relationship to auditory processing. It is predicted that urbanization may impose novel stressors on animals, leading to differences in this hormone across urban and rural birds. We seek to understand if differences in CORT levels could impact animals' …


The Role Of Cholinergic Ventral Pallidum Cells In Effortful Motivation, Elizabeth A. Bien Apr 2025

The Role Of Cholinergic Ventral Pallidum Cells In Effortful Motivation, Elizabeth A. Bien

Dartmouth College Ph.D Dissertations

Maladaptive reward-seeking behavior can be driven by one of several different components including excessive craving elicited by cues that predict rewards, failing to effortfully pursue rewards when it is beneficial to do so, and compulsively seeking rewards when it is no longer advantageous to do so. This thesis includes experiments focusing on these three different components of reward-seeking behavior to better understand how reward-seeking can become maladaptive. First, we wanted to examine the role that sex plays in the acquisition and compulsiveness of sign-tracking behavior in the Long Evans rat, a strain that is commonly used as the background for …


Local Nutrient Addition Drives Plant Diversity Losses But Not Biotic Homogenization In Global Grasslands, Qingqing Chen, Shane A. Blowes, W. Stanley Harpole, Emma Ladouceur, Elizabeth T. Borer, Andrew Macdougall, Erika Hersch-Green, Et Al. Apr 2025

Local Nutrient Addition Drives Plant Diversity Losses But Not Biotic Homogenization In Global Grasslands, Qingqing Chen, Shane A. Blowes, W. Stanley Harpole, Emma Ladouceur, Elizabeth T. Borer, Andrew Macdougall, Erika Hersch-Green, Et Al.

Michigan Tech Publications

Nutrient enrichment typically causes local plant diversity declines. A common but untested expectation is that nutrient enrichment also reduces variation in nutrient conditions among localities and selects for a smaller pool of species, causing greater diversity declines at larger than local scales and thus biotic homogenization. Here we apply a framework that links changes in species richness across scales to changes in the numbers of spatially restricted and widespread species for a standardized nutrient addition experiment across 72 grasslands on six continents. Overall, we find proportionally similar species loss at local and larger scales, suggesting similar declines of spatially restricted …

Examining Physiological Responses To Misophonic Triggers, Christian O'Reilly, Xuan Yang, Sewon Oh, Doug Wedell, Svetlana Shinkareva Apr 2025

Examining Physiological Responses To Misophonic Triggers, Christian O'Reilly, Xuan Yang, Sewon Oh, Doug Wedell, Svetlana Shinkareva

Faculty Publications

We collected and analyzed an array of biosignals (face electromyogram, skin electrodermal activity, peripheral temperature, and electrocardiogram) in 60 participants with and without misophonia, a condition characterized by decreased tolerance to innocuous sounds. Our goal was to objectively characterize the physiological response to misophonia triggering sounds. We found that misophonic responses can be objectively identified in some cases through atypical physiological reactions to triggering stimuli, though not all participants exhibited this response. Our analyses suggest a large interindividual variability in response to misophonic triggers and highlights the need for methodological adjustments in future experiments to increase the detectability of misophonic …

Faculty, Staff and Student Publications

This study aims to characterize and compare the functional neural networks associated with different olfactory stimuli, including air, non-social odours, and human body odours. We introduce a novel processing pipeline based on event-related functional magnetic resonance imaging (fMRI) and graph theory for network identification. To ensure the stability and small worldness of the characterized networks, we conduct statistical validations, network modularity assessments, and robustness measurement against local attacks. The key hypothesis is that human body odours (so-called social odours) and non-social odours engage distinct neural networks, particularly in regions responsible for social processing. We found that the posterior medial orbitofrontal …
