Neurobiological Mechanisms Of Cognitive Processing Therapy For Post-Traumatic Stress Disorder: A Brain Network Approach, Tessa Vuper Jun 2020

Neurobiological Mechanisms Of Cognitive Processing Therapy For Post-Traumatic Stress Disorder: A Brain Network Approach, Tessa Vuper

Dissertations

Psychotherapy research is increasingly targeting both psychological and neurobiological mechanisms of therapeutic change. This trend is evident in and applicable to post-traumatic stress disorder (PTSD) treatment research given the high nonresponse rate of individuals with PTSD who undergo cognitive-behavioral therapy (CBT). A review of the literature investigating neurobiological mechanisms of CBT in PTSD reveals inconsistent results that fail to fully support dual process or learning models of CBT effects in the brain. However, network-based models of psychopathology provide a new framework from which to understand both mental disorder symptoms and therapeutic mechanisms. The current study investigated a) whether brain networks …


Sedative And Neurotoxic Properties Of Brexanolone Compared To Midazolam In The Developing Rodent Brain, Jacob Huffman Apr 2020

Sedative And Neurotoxic Properties Of Brexanolone Compared To Midazolam In The Developing Rodent Brain, Jacob Huffman

Dissertations

The developing brain is susceptible to extensive neurotoxicity following exposure to sedative/anesthetic drugs (SADs). Every year hundreds of thousands of children around the world are exposed to SADs with no viable non-neurotoxic agents approved for clinical use. Allopregnanolone (AlloP) has well-established sedative effects in adults and neonates. AlloP and many SADs produce sedation/anesthesia through allosteric modulation of GABAA receptors, which is one of two principal mechanisms behind SAD-induced neurotoxicity. Evidence suggests AlloP has the unique capacity to regulate key apoptotic factors in adults and is widely involved with critical stages of neurodevelopment, indicating this neurosteroid might serve as a …


More Than Just Words On A Screen: A Biopsychosocial Approach To Understanding Effects Of Race-Related Media, Melinda Kittleman Mar 2020

More Than Just Words On A Screen: A Biopsychosocial Approach To Understanding Effects Of Race-Related Media, Melinda Kittleman

Dissertations

Racial disparities in physical and mental health are ongoing and well-documented problems in the United States. Black Americans, compared to White Americans, have higher risk of obesity, heart disease, cancer, depression, and substance abuse. Research suggests prejudice and discrimination play a role in racial health disparities. Everyday discrimination is considered a chronic, psychosocial stressor that impacts the health of Black Americans. A biopsychosocial approach states there are various factors that contribute to the pathway from discrimination to disease and proposes complex relationships that explain effects of racial discrimination on health. The current study examined social factors (race-related media), biological factors …
