While appraisal and coping are known to impact adolescent psychopathology, more vulnerable or resilient responses to stress may depend on individual temperament. This study examined early life temperament as a moderator of the prospective relations of pre-adolescent appraisal and coping with adolescent psychopathology. The sample included 226 (62% female, 14–15 years) adolescents with assessments starting at 3 years of age. Adolescents were predominately White (12% Black 9% Asian, 11% Latinx, 4% Multiracial, and 65% White). Observed early-childhood temperament (fear, frustration, executive control, and delay ability) were tested as moderators of pre-adolescent coping (active and avoidant) and appraisal (threat, positive) on …

Memory And Attention While Scuba Diving At Shallow And Deep Depths: An Open Water Study, Leanne Boucher, Joshua Feingold, Kelly Concannon, Stephanie Talavera, Jaime Tartar, W. Matthew Collins
Journal for Sports Neuroscience
SCUBA diving requires a high level of cognitive functioning, however, many divers anecdotally report poor memory and attentional skills while underwater. Few studies have documented cognitive deficits resulting from an open-water dive. Here, 23 divers completed both shallow (8 m) and deep (28 m) dives over two days in the open-water. The order of the dives was counterbalanced across participants. While at depth, they completed the State-Trait Anxiety Inventory to assess anxiety levels, learned and were tested on a list of 36 words, and completed the trail making task (TMT) to assess executive functioning. They also gave saliva samples to …

Sleep deficiency is now considered an emerging global epidemic associated with many serious health problems, and a major cause of financial and social burdens. Sleep and mental health are closely connected, further exacerbating the negative impact of sleep deficiency on overall health and well-being. A major drawback of conventional treatments is the wide range of undesirable side-effects typically associated with benzodiazepines and antidepressants, which can be more debilitating than the initial disorder. It is therefore valuable to explore the efficiency of other remedies for complementarity and synergism with existing conventional treatments, leading to possible reduction in undesirable side-effects. This review …
Stress-Related Psychopathology During The Covid-19 Pandemic, Katie A. Mclaughlin, Maya L. Rosen, Steven W. Kasparek, Alexandra M. Rodman
Stress-Related Psychopathology During The Covid-19 Pandemic, Katie A. Mclaughlin, Maya L. Rosen, Steven W. Kasparek, Alexandra M. Rodman
Neuroscience: Faculty Publications
The COVID-19 pandemic has introduced widespread societal changes that have required ongoing adaptation. Unsurprisingly, stress-related psychopathology has increased during the pandemic, in both children and adults. We review these patterns through the lens of several leading conceptual models of the link between stress and psychopathology. Some of these models focus on characteristics of environmental stressors—including cumulative risk, specific stressor types, and stress sensitization approaches. Understanding the specific aspects of environmental stressors that are most likely to lead to psychopathology can shed light on who may be in most need of clinical intervention. Other models center on factors that can buffer …
The Role Of The Prefrontal Cortex And Stress In Huntington Disease-Mediated Aggression, Kadambari Vyas
The Role Of The Prefrontal Cortex And Stress In Huntington Disease-Mediated Aggression, Kadambari Vyas
Honors Undergraduate Theses
Huntington Disease (HD) is a fatal neurodegenerative disorder that is characterized by motor, cognitive, and psychiatric symptoms. Although HD onset is determined by motor symptoms, psychiatric symptoms, like depression and aggression, can develop earlier, have a larger impact on quality of life, and are understudied due to stigma. Our lab has observed hyper aggression in our humanized HD mouse model (Hu97/18) compared to our knock-in HD mouse model (Q175FDN). We characterized these differences and found that the Hu97/18 mice overreact in neutral situations, behaving as if they are in threatening situations. We are now using this novel model of HD-related …
Stress And The City: The Impacts Of City Living And Urbanization On Mental Health, Natalie Akins
Stress And The City: The Impacts Of City Living And Urbanization On Mental Health, Natalie Akins
Scripps Senior Theses
Urbanization is causing a demographic and cultural shift to the landscape of cities across the globe. Although urban living can be advantageous for both individual and societal growth, it can negatively affect mental health and wellbeing. Individuals living in urban environments have an increased risk for mental disorders like depression and schizophrenia. Certain challenges common in urban environments and associated with increased stress, may be causing the increase with mental illness. Chronic stress and the subsequent hyperactivation of the hypothalamic-pituitary-adrenal axis and sustained synthesis of glucocorticoids is detrimental to metabolic, endocrine, and immunologic processes. The overexposure to glucocorticoids can lead …
Chronic Adolescent Stress As A Predictive Factor For The Risk Of Developing Ptsd-Like Symptoms In Adulthood, Grace K. Young
Chronic Adolescent Stress As A Predictive Factor For The Risk Of Developing Ptsd-Like Symptoms In Adulthood, Grace K. Young
Theses and Dissertations
Post-traumatic stress disorder is a stress and trauma based psychological disorder that is defined by the DSM-IV as an anxiety disorder that affects approximately 7.8% of people in the United States. PTSD is when those who suffer a traumatic event have intense and distressing feelings, emotions, and memories for a prolonged period of time after the event. A prominent feature of PTSD is the impaired ability to properly extinguish a fear response after a dangerous trigger or stressor is no longer present, also known as safety learning. Stressors are threats perceived within the environment that activate a response within the …
Estrogen Modulation Of Vta Dopamine Neuron Physiology And Behavioral Responsivity To Variable Social Stressors, Mary R. Shanley
Estrogen Modulation Of Vta Dopamine Neuron Physiology And Behavioral Responsivity To Variable Social Stressors, Mary R. Shanley
Dissertations, Theses, and Capstone Projects
The behavioral output of different animals, or even the same animal in different contexts, is remarkably variable in response to the same external stimulus. This behavioral diversity is due to the complex integration of external and internal stimuli, through both neuronal and hormonal signals that selects the best behavioral response. By their nature as long-distance signaling molecules, hormones play a critical role in communicating information about internal states across the organism. Many hormones produced in the periphery target the central nervous system to modulate animal behavior, selecting for behaviors that are appropriate over behaviors that are maladaptive in that specific …
A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab
A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab
Dissertations, Theses, and Capstone Projects
Deep breathing practices have shown promise in reducing stress, anxiety, and depression in different populations, including young adults. Specifically, resonant frequency breathing can exert an impact on stress response systems through the vagus nerve and the hypothalamo-pituitary-adrenal (HPA) axis. This may induce reductions in stress and improvement in emotion regulation. Young adults, including college students, tend to be at a higher risk for psychological distress, as they face several psychosocial challenges. The COVID-19 pandemic has imposed new and unique stressors that resulted in higher levels of stress and emotional symptoms and it has been shown that this may have placed …
The Disproportionate Impact Of Covid-19 On Women, Ava Stallone
The Disproportionate Impact Of Covid-19 On Women, Ava Stallone
Honors Scholar Theses
The impact of COVID-19 is placing a large strain on women. This can be seen through reports of mental health and financial concerns. Women are more vulnerable to COVID-19 related economic effects due to existing gender inequalities, which in turn may also have a negative effect on mental health. Through this study gender disproportion is looked at between mental health and COVID-19 financial concerns among women and men. The aim is to asses how COVID-19 financial concerns may be contributing to stress, anxiety, and depression. It is hypothesized that; women will report worse mental health and greater economic concerns than …

Long-Term Impacts Of Acute Stressor Exposure On Locus Coeruleus Function And Anxiety-Like Behavior In Rats, Olga Borodovitsyna
Long-Term Impacts Of Acute Stressor Exposure On Locus Coeruleus Function And Anxiety-Like Behavior In Rats, Olga Borodovitsyna
Graduate School of Biomedical Sciences Theses and Dissertations
Stress is a physiological state characterized by behavioral arousal that occurs during exposure to harmful or threatening stimuli, and usually facilitates an adaptive behavioral response. The persistence of stress sometimes causes it to become maladaptive, potentially contributing to disease development, including physiological complications with altered neuroendocrine signaling and impaired function of organ systems, and psychological conditions including depression and anxiety. Anxiety disorders in particular are associated with a history of stress and are the most common class of mental disorders, with a lifetime prevalence of 33.7% in the general population. The locus coeruleus (LC) is a major node in the …
Behavioral, Endocrine, And Neural Responses To Stress In Postpartum And Nulliparous Rats : Potential Mechanisms Of Postpartum Stress Resilience, Joanna Medina
Legacy Theses & Dissertations (2009 - 2024)
Major depressive disorder is one of the most pervasive psychiatric illnesses in the United States. Women are at greater risk for developing depression, particularly during their childbearing years. Approximately 17% of new mothers develop postpartum depression within 4 weeks after parturition. The risk for postpartum depression is even greater in women who do not breastfeed or stop breastfeeding early. Major depressive disorder and postpartum depression share the same symptomology and common etiological bases. Dysregulated stress responses, dopamine activity, and neuroinflammation are recognized mechanisms for depression. The transition to motherhood encompasses physiological and behavioral adaptations in the brain essential for ensuring …

The Relationship Between Stress And Quality Of Life In People With Multiple Sclerosis: The Mediating Role Of Resilience, Byung Jin Kim
Theses and Dissertations--Early Childhood, Special Education, and Counselor Education
Multiple sclerosis (MS) is a chronic disease of the central nervous system encompassing the brain, spinal cord, and optic nerve, in which the patient’s immune system attacks healthy cells and tissues. Due to the unpredictable characteristics of the disease, MS can lead to an unusually high level of stress and may negatively impact the individual’s QoL. Resilience is a psychological structure that shows positive coping and adaptive ability from difficult or stressful situations. Resilience also indicates a buffering effect on the stressors of individuals with disabilities and serves to protect psychological health and function from disability. The purpose of this …
The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, Anna Hallowell
The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, Anna Hallowell
The Journal of Purdue Undergraduate Research
Despite years of research to understand under-lying mechanisms and develop more effective treatment approaches for mood disorders, numerous challenges exist. Many chronic stress models are used to study mood disorders, how-ever the majority have been established with adult males. This is problematic considering that affective disorders are more common in women, and generally develop during late adolescence. Studies have indicated fundamental behavioral, physiological, and neural differences between males and females in response to the same external stressors, furthering a need to develop sex-specific paradigms to accurately model the etiology of mood disorders in females. The Wistar-Kyoto (WKY) rat strain is …
Effects Of Repeated Intermittent Episodes Of Social Stress On The Acquisition And Extinction Of A Reward-Seeking Task, Nikki Sullivan
Effects Of Repeated Intermittent Episodes Of Social Stress On The Acquisition And Extinction Of A Reward-Seeking Task, Nikki Sullivan
Honors Theses
Repeated exposure to stress is known to have a myriad of effects on the brain, contributing to the development of psychiatric disorders, such as anxiety, depression, and drug addiction. For example, rats undergoing repeated social stress develop increased cocaine self-administration. These effects of stress are not well-understood and are related to changes in the brain reward system. This study investigated the effects of repeated social stress on reward-seeking behavior via the acquisition and extinction of a discriminative stimulus (DS) task and on anxiety-like behavior in the elevated plus maze (EPM). Male rats underwent intermittent social defeat (4 sessions in 10 …

Center for Brain, Biology, and Behavior: Faculty Publications
This study sought to address the complex interplay between both biological and psychological perceptions of stress and sleep in the acute stages following a mild traumatic brain injury. A secondary goal was to identify potential targets for intervention. Eleven acutely injured youth (mean age 12 years) were studied at home with overnight actigraphy, salivary cortisol and melatonin assays, and subjective ratings of stress and fatigue (injured group). Nine matched control youth also were assessed (control group). Results suggested longer sleep latencies (time to fall asleep) and higher levels of fatigue in the injured group exist (p ¼ 0.025 and p …
Alterations In Corticotropin-Releasing Factor Receptor Type 1 In The Hypothalamus And Preoptic Area During The Postpartum Period, Rose Ann M. De Guzman
Alterations In Corticotropin-Releasing Factor Receptor Type 1 In The Hypothalamus And Preoptic Area During The Postpartum Period, Rose Ann M. De Guzman
Legacy Theses & Dissertations (2009 - 2024)
Despite the apparent sex difference in prevalence of anxiety in humans, pre-clinical studies that have led to anxiolytic drug discoveries between 1960 and 2012 used male animals and approximately 6% of 10,000 studies used female animals. The generalizability of the efficacy of these drugs to both sexes may be limited if data derived are predominantly based on the male brain. The purpose of this dissertation, therefore, was to investigate potential underlying neuronal mechanisms that could be contributing to the sex differences in stress-related mood disorder prevalence and to focus on shedding light on female brains.

Validation Of Metabolic And Immunologic Biomarkers Tnf-A, Igf, Il-6, Crp And Hair Cortisol In The Common Marmoset, Sushmita Adhikari, Mariah Wulf, Aaryn Mustoe Phd, Jeffrey French Phd
Theses/Capstones/Creative Projects
The common marmoset is a good model for research because they are easy to house and have complex social relationships (French et al., 2019). Marmosets are sensitive to social isolation, and when introduced to a stressor, the HPA axis is activated (Saltzman & Abbott, 2011). The purpose of this experiment is to validate marmosets as a translational model for stress due to social relationships in humans. This is done by validating biomarker concentration levels at baseline, then comparing the concentration when introduced to a stressor. The biomarkers IL-6, CRP, IGF-1 and TNF-a were tested using a serum assay, then running …

Departmental Papers (Biology)
This study assessed the role of stress systems in the nucleus accumbens (NAc) in promoting sex differences in the reinforcing effects of nicotine. Intravenous self-administration (IVSA) of various doses of nicotine was compared following overexpression of corticotropin-releasing factor (CRF) in the NAc of female and male rats. Ovariectomized (OVX) females were also included to assess the role of ovarian hormones in promoting nicotine reinforcement. Rats received intra-NAc administration of an adeno-associated vector that overexpressed CRF (AAV2/5-CRF) or green fluorescent protein (AAV2/5-GFP). All rats were then given extended access (23 h/day) to an inactive and an active lever that delivered nicotine. …
The Drosophila Neuroblasts: A Model System For Human Ribosomopathies, Sonu Shrestha Baral
The Drosophila Neuroblasts: A Model System For Human Ribosomopathies, Sonu Shrestha Baral
LSU Doctoral Dissertations
This dissertation describes the use of Drosophila neuroblasts (NBs) to model human ribosomopathies; the overall goal is to understand why specific stem cell and progenitor cell populations are the primary targets in nucleolar stress as seen in the ribosomopathies. Chapter 1 provides an overview of relevant literature. Chapter 2 describes nucleolar stress in Drosophila neuroblasts as a model for human ribosomopathies. For this, we induce nucleolar stress by using the UAS-GAL4 system to express RNAi that depletes Nopp140 transcripts, and we also employ homozygous, CRISPR-Cas9-generated Nopp140 gene disruptions with a systemic null phenotype (Nopp140-/-). Embryonic lethality was observed …

Characterization Of A Novel, Stress-Responsive Sexually Dimorphic Corticotropin-Releasing Factor Receptor 1 (Crfr1) Nucleus In The Rostral Anteroventral Periventricular Nucleus Of The Mouse, Zachary Julius Rosinger
Legacy Theses & Dissertations (2009 - 2024)
Within the United States, women are at double the risk of men to develop a stress-related mood disorder (e.g., anxiety or depression) during their reproductive years (Kornstein et al., 2000; Kessler et al., 2005). Many factors contribute to the potential sex difference in such disorders, including gonadal hormones (hypothalamic-pituitary-gonadal axis; HPG) and how they interact with the stress response system, or hypothalamic-pituitary-adrenal (HPA) axis. Corticotropin-releasing factor (CRF) signals through binding the GS-coupled receptor, CRF receptor 1 (CRFR1), and activity between CRF/CRFR1 regulates the hormonal and behavioral stress response (Chen et al., 1993; Bale and Vale, 2004; Heinrichs et al., 1995; …

It is well known that young organisms do not maintain memories as long as adults, but the mechanisms for this ontogenetic difference are undetermined. Previous work has revealed that the α-amino-3-hydroxy-5-methyl-4isoxazolepropionic acidreceptor (AMPAr)subunits aretraffickedinto the synaptic membranefollowing memory retrieval in adults. Additionally, phosphorylated PSD-95-pS295 promotes AMPAr stabilization at the synapse. We investigated these plasticity related proteins as potential mediators in the differential contextual stress memory retrieval capabilities observed between adult and juvenile rats. Rats were assigned to either pedestal stress (1h) or no stress control (home cage). Each animal was placed alone in an open field for 5minat the base …

Brain development and behavior are sensitive to a variety of environmental influences including social interactions and physicochemical stressors. Sensory input in situ is a mosaic of both enrichment and stress, yet little is known about how multiple environmental factors interact to affect brain anatomical structures, circuits and cognitive function. In this study, we addressed these issues by testing the individual and combined effects of sub-adult thermal stress, larval density and early-adult living spatial enrichment on brain anatomy and olfactory associative learning in adult Drosophila melanogaster. In response to heat stress, the mushroom bodies (MBs) were the most volumetrically impaired among …

The Psychophysiological Correlates Of Personality, Trauma, Posttraumatic Stress Disorder And Social Support, Meghan E. Pierce
UNLV Theses, Dissertations, Professional Papers, and Capstones
Theories considering the etiology of psychopathy suggest that trauma exposure, specifically childhood maltreatment and sexual abuse, is related to the development of callous-unemotional traits in children and adolescents, which are precursors to psychopathic traits in adulthood. Furthermore, posttraumatic stress disorder has an opposite relationship with many of the emotional and behavioral components of the two-factor model of psychopathy. Specifically, PTSD is positively associated to IA and traits associated with it and negatively associated with FD. Thus, this study sought to expand upon the current theories of a trauma-based etiology of psychopathy by investigating the relationship between trauma, PTSD, and psychopathic …
Central Role Of Vasotocin In The Neuroendocrine Regulation Of Stress Responses And Food Intake In Chickens, Gallus Gallus, Gurueswar Nagarajan
Central Role Of Vasotocin In The Neuroendocrine Regulation Of Stress Responses And Food Intake In Chickens, Gallus Gallus, Gurueswar Nagarajan
Graduate Theses and Dissertations
It is well known that arginine vasotocin (AVT) in birds is involved in physiological homeostasis such as cardiovascular, osmotic regulation as well as reproductive functions. Pertinent to these physiological functions, AVT immunoreactive (-ir) neurons in the hypothalamus have been found associated with hemorrhage, dehydration, oviposition and other physiological regulation. Evidence, however, suggests that AVT also plays significant roles in modulating behavior, memory, stress, and food intake. This dissertation research addresses the latter two neuroendocrine functions of AVT in detail within the chicken brain. First, the functional role of AVT-ir neurons in conjunction with corticotropin releasing hormone (CRH)-ir neurons in the …
