Effects Of Development On Hpa Function Following Pubertal Stress, Brittany D. Elliott
Effects Of Development On Hpa Function Following Pubertal Stress, Brittany D. Elliott
Graduate Theses, Dissertations, and Problem Reports
For women, two of the greatest risk factors for affective disorders are adversity experienced during puberty and later becoming pregnant. We have created a translationally relevant mouse model where we address these complex risk factors. Previously, we discovered that pregnant mice (dams) that experienced chronic variable stress (CVS) during puberty display a blunted hypothalamic-pituitary-adrenal (HPA) response when exposed to an acute stressor. Interestingly, this alteration only first becomes apparent during pregnancy, which is a sensitive period for these effects due to normative neuroendocrine changes. Further investigation of the mechanisms underlying this dysfunction revealed altered gene expression in the paraventricular nucleus …
Negative Social Media And Its Influence On Athlete's Performance, Bernd R. Huber
Negative Social Media And Its Influence On Athlete's Performance, Bernd R. Huber
Cal Poly Humboldt theses and projects
This study aimed to investigate the potential impact of negative social media content on athletes' cortisol levels and subsequent performance. The study focused on the change in cortisol levels and differences in free throw performance, based on previous research findings. We hypothesized that negative social media postings would increase the stress experienced by student-athletes, resulting in elevated cortisol levels and decreased performance. Additionally, participants (n = 8) completed a questionnaire to examine the interaction between preexisting fear and the biological stress response. Contrary to expectations, there was no significant change in stress response, and negative postings did not have …
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 Relationship Between Stress And Quality Of Life In People With Multiple Sclerosis: The Mediating Role Of Resilience, Byung Jin Kim
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 …
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 …

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; …
Evaluation Of Neurobiological Risk Factors For Alcohol Consumption; Convergent Evidence For Predispositional Effects Of Brain Volume, David Baranger
Evaluation Of Neurobiological Risk Factors For Alcohol Consumption; Convergent Evidence For Predispositional Effects Of Brain Volume, David Baranger
Arts & Sciences Electronic Theses and Dissertations
Alcohol is one of the most widely used psychoactive substances and accounts for 5% of global disease burden. The goal of the present work is to help advance efforts to both identify prognostic markers of risk, and to understand the mechanisms by which alcohol consumption impacts health. Early life stress is one of the strongest predictors of mental illness, including alcohol dependence, and has been hypothesized to impact risk via modulation of striatal reward functions and reward learning. Studies examined the effect of stress on reward learning and processing, and tested for moderation by genetic and environmental risk. Results were …
Hpa Axis Genetic Variation And Life Stress Influences On Functional Connectivity In Resting State Networks, Tara Ann Miskovich
Hpa Axis Genetic Variation And Life Stress Influences On Functional Connectivity In Resting State Networks, Tara Ann Miskovich
Theses and Dissertations
Stressful or traumatic experiences are a key risk factor for developing psychopathology, primarily through the impact that chronic stress has on hypothalamic-pituitary-adrenal (HPA) axis functioning. The HPA axis regulates the stress response but can become dysregulated with chronic activation and impact brain functioning. In addition to environmental stressors, genetic variation in genes in the HPA axis appear to influence HPA axis functioning and is also related to disruption in brain functioning, particularly in the context of high life stress. The current study focused on examining potential mechanisms through which trauma and stress interacts with HPA axis genes to impact key …
Mindfulness And Law Enforcement: An Effective Approach To Implementing Mindfulness For First Responders, Gina White
Mindfulness And Law Enforcement: An Effective Approach To Implementing Mindfulness For First Responders, Gina White
Mindfulness Studies Theses
An increasing number of studies show that people employed as first responders in high trauma service jobs tend to experience a high level of stress, at work and after hours. Studies suggest that constant exposure to job related stress leads to both physical and mental dysregulation. This study looks at the effects of implementing mindfulness tools and techniques to those working in law enforcement. Other works on this topic report mindfulness as a successful tool to increase wellbeing to a broad spectrum of populations. The methodology used in this study was designed specifically for first responders. The data findings were …
The Psychophysiological Correlates Of Personality, Trauma, Posttraumatic Stress Disorder And Social Support, Meghan E. Pierce
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 …
Working Memory Impairments In Chromosome 22q11.2 Deletion Syndrome: The Roles Of Anxiety And Stress Physiology, Ashley F. P. Sanders
Working Memory Impairments In Chromosome 22q11.2 Deletion Syndrome: The Roles Of Anxiety And Stress Physiology, Ashley F. P. Sanders
University of New Orleans Theses and Dissertations
Stress and anxiety negatively impact the working memory system by competing for executive resources. Broad memory deficits have been reported in individuals with chromosome 22q11.2 deletion syndrome (22q11.2DS). We investigated anxiety and physiological stress reactivity in relation to visuospatial working memory impairments in 20 children with 22q11.2DS and 32 typically developing children (M = 11.10 years, SD = 2.95). Results indicate reduced post-stress RSA recovery and overall increased levels of cortisol in children with 22q11.2DS. Additionally, anxiety mediated the relationship between 22q11.2DS and visuospatial working memory impairment. However, there was no indication that stress response physiology mediated this association. …

The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson
Electronic Theses and Dissertations
Acute stress is commonly experienced by many throughout their lives. Given the demanding lifestyle of many career paths, it's important to gauge the influence of these stressors upon cognitive performance. The present dissertation focus' upon explicit learning in attempts to explore one avenue of the stress-cognition relationship. The Trier Social Stress Test (TSST) was used as a lab stressor for Experiments 1 and 2, in which participants are asked to give a speech and complete a difficult math task in front of 2 evaluators trained to monitor non-verbal behavior. Experiment 1 investigates the dynamic stress response during the minutes following …
The Influence Of Prenatal Stress On Behaviors Associated With Schizophrenia And Autism Spectrum Disorder., Harold Bauerle
The Influence Of Prenatal Stress On Behaviors Associated With Schizophrenia And Autism Spectrum Disorder., Harold Bauerle
Graduate College Dissertations and Theses
Disorders such as schizophrenia (SCZ) and austism spectrum disorder (ASD) have long been associated with prenatal stress. In these three experiments, we attempted to correlate stress during gestation with behaviors considered to have good facial validity with SCZ and ASD in both juvenile and adult animals. To differentiate the effects of prenatal stress (PS) from the effects of early life stress due to a dam's behavior (MS), half of offspring animals were cross fostered to dams treated in the alternative condition as the offspring during pregnancy in experiments 2 and 3. In experiment 1, but not in 2 or 3, …
Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens
Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens
Walden Dissertations and Doctoral Studies
There is a limited research base on low voltage brain conditions, which are characterized by electrical activity being measured at below 20 microvolts. The purpose of this study was to examine the relationship between saliva cortisol levels and voltage using an EGG in a college student population. Illuminating this relationship is important to inform how low voltage conditions can affect daily memory and cognitive functioning of undergraduate college students that may be a result of stress. The college student population may be vulnerable to the low voltage condition because of stress from the transition between teenage and adult life and …

Alcohol Use Disorders And An Fmri Stress Task: A Connectivity Analysis, Natasha E. Wright
Theses and Dissertations
Little research has been conducted on neuronal stress processing in individuals
with alcohol dependence (AD). The present study examined neural stress response in AD individuals compared to controls using an fMRI stress task, assessing amygdala
activation and its connectivity to the medial prefrontal cortex (mPFC). Further, the study
analyzed the impact of hormone levels and subjective stress on frontal-limbic
connectivity patterns.
Ten abstinent AD individuals and 11 controls were recruited. Subjects
participated in an fMRI stress task. A region of interest (amygdala) analysis was
conducted using area-under-the-curve. This activation was then examined in a whole brain functional connectivity analysis. Follow-up …
Associations Between Hypothalamic-Pituitary-Adrenal Axis System Gene Variants And Cortisol Reactivity In Preschoolers: Main Effects And Gene-Environment Interactions, Haroon I. Sheikh
Electronic Thesis and Dissertation Repository
Exposure to stressful events during early development has consistently been shown to produce long lasting effects on the hypothalamic-pituitary-adrenal (HPA) axis, which may increase vulnerability to mood and anxiety disorders. Recently reported genetic association studies indicate that these disorders may be influenced, in part, by gene-environment interactions (GxE) involving polymorphisms within the corticotrophin-releasing hormone and monoaminergic system genes. However, little is known about how genetic variants and life stress work to shape children’s neuroendocrine reactivity and emerging symptoms. Therefore, the aim of this thesis is to examine main effects of candidate genes and GxE on the neuroendocrine stress response and …
Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres
Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres
University of New Orleans Theses and Dissertations
Stress has been widely shown to directly influence people’s emotional and behavioral processing as well as their underlying biological systems. This project examined physiological and behavioral responses as indicators of stress and coping in the context of a psychosocial stressor in a controlled laboratory setting. We examined the association between indicators of behavioral coping and underlying physiological reactivity within participants while experiencing stress. Participants included 68 emerging adults. Physiological measures include autonomic biomarkers (e.g., heart-rate, skin conductance) at rest and during the stressor while behavioral indicators that were coded include acute verbal and non-verbal actions exhibited by participants during the …
