Methamphetamine-Induced Modulation Of Anxiety/Depressive-Like Behaviors And Hpa Axis Output : Contributing Factors Within Stress Associated Brain Regions, Jason Jacobskind
Methamphetamine-Induced Modulation Of Anxiety/Depressive-Like Behaviors And Hpa Axis Output : Contributing Factors Within Stress Associated Brain Regions, Jason Jacobskind

Methamphetamine (MA) is a psychostimulant drug of addiction that induces a wide range ofeffects. Among its many side effects is the potentiation of cellular, physiological, and behavioral changes in the stress response system. Upon exposure, the hypothalamic-pituitary-adrenal (HPA) axis is initiated. This process entails many factors. Receiving input from other brain regions, the paraventricular nucleus (PVN) of the hypothalamus secretes corticotropin-releasing factor (CRF) and arginine vasopressin into the anterior pituitary gland. These together stimulate the synthesis and release of adrenocorticotropic hormone, which circulates via the blood stream to cause the release of glucocortoicoids, the stress hormone (CORT). Binding of glucocorticoids …
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 Impact Of Stress On Steroid Hormones And Cue Reactivity In Smokers And Gamblers, Stephanie Elaine Wemm
The Impact Of Stress On Steroid Hormones And Cue Reactivity In Smokers And Gamblers, Stephanie Elaine Wemm
Legacy Theses & Dissertations (2009 - 2024)
Addictions, both substance and behavioral, have been conceptualized as having similar biopsychosocial processes with different opportunistic expressions (Shaffer et al., 2004). Biological processes such as the hormonal response to stress as measured by cortisol, dehydroepiandrosterone (DHEA), and the ratio of the DHEA/cortisol may be among the variables underlying the disposition to develop an addictive disorder, regardless of whether it is a substance-based or a so-called behavioral addiction. The current study aimed to examine whether physiological and psychological reactions to stress are similar in high-frequency smokers and gamblers. The subjective (urges, cravings) and physiological responses (skin conductance and heart rate) of …
Exploring The Impact Of Meditation On Attentional Allocation To Emotion, Sychopathology, And Acute Stress, In A Community Sample With Mixed Anxiety And Depression, Nicholas Thomas Van Dam
Exploring The Impact Of Meditation On Attentional Allocation To Emotion, Sychopathology, And Acute Stress, In A Community Sample With Mixed Anxiety And Depression, Nicholas Thomas Van Dam
Legacy Theses & Dissertations (2009 - 2024)
Attempts to define mindfulness in the clinical and psychological sciences have been marred by contradictions, inconsistencies, and controversies. In this wait-list (WL) controlled mindfulness meditation training (MMT) study, the efficacy and potential mechanisms of MMT was tested in a community sample with undiagnosed, but significant, symptoms of anxiety, depression, and stress. In a pre/post design, which also included 3 month follow-up, participants completed self-report measures, participated in a psychosocial stress task (before and after which they completed self-report mood questionnaires and had physiological and salivary neuroendocrine markers collected), and completed an emotional attentional blink paradigm. Compared to WL (n = …
Glossolalia Influences On Stress Response Among Apostolic Pentecostals, Christopher Dana Lynn
Glossolalia Influences On Stress Response Among Apostolic Pentecostals, Christopher Dana Lynn
Legacy Theses & Dissertations (2009 - 2024)
This study tests the hypothesis that long–term experience of Apostolic Pentecostal glossolalia or “speaking in tongues” reduces the reactivity of biological stress response to normal or "daily" stressors. Glossolalia is a form of religious dissociation. Dissociation is a universal capacity often conflated with “trance.” It refers to the partitioning of awareness associated with a variety of cross–cultural forms, from daydreaming and denial to possession trance, shamanic spirit journeys, and dissociative identity disorder. Dissociation is believed to reduce or filter stress by mediating evaluation of potential stressors and reactivity of the mechanisms of biological stress response. Previous studies have examined these …
