The Effects Of Early Corticosterone Treatment On The Development Of The Avian Song Control System, Mahin Shahbazi
The Effects Of Early Corticosterone Treatment On The Development Of The Avian Song Control System, Mahin Shahbazi
Neuroscience Institute Dissertations
Stress has long lasting effects on physiology, development, behavior, reproductive success and survival. These effects are mediated by glucocorticoids, such as corticosterone (Cort), via glucocorticoid receptors (GR), though the exact mechanisms underlying these effects are unknown. Early developmental stress affects the size of the avian song control nuclei (particularly HVC; proper name) and song quality in many songbirds, suggesting a direct link between brain and behavior. HVC is required for song learning and production. The complexity of the male zebra finch (Taeniopygia guttata) courtship song is important in female mate choice. Although the mechanisms behind the effects of …
The Relationships Between Perfectionism, Stress, Coping Resources, And Burnout Among Sign Language Interpreters, Tomina J. Schwenke
The Relationships Between Perfectionism, Stress, Coping Resources, And Burnout Among Sign Language Interpreters, Tomina J. Schwenke
Counseling and Psychological Services Dissertations
The multidimensional construct of perfectionism is well studied as it relates to coping with stress and burnout (Flett & Hewitt, 2002). Bontempo and Napier (2011) identify the personality trait of conscientiousness, which includes perfectionistic traits, as beneficial to an interpreter’s job performance. In contrast, several studies suggest that constructs related to maladaptive perfectionistic traits play a role in the development of burnout among interpreters, although perfectionism has not been explicitly identified or used as a research variable (Qin, Marshall, Mozrall, & Marschark, 2008). These studies identify key components of both adaptive and maladaptive perfectionism in the assessment of stress-related outcomes, …
Peripheral And Central Mechanisms Through Which High Energy Diets Impair Hippocampal-Dependent Memory In Male Rats, Amy Patricia Ross
Peripheral And Central Mechanisms Through Which High Energy Diets Impair Hippocampal-Dependent Memory In Male Rats, Amy Patricia Ross
Neuroscience Institute Dissertations
Over the past five decades, per capita caloric intake has increased by approximately 28% in the United States. A hallmark of the current standard American diet is an excess of energy sources from saturated fat and refined carbohydrates. High energy diets such as the “Western” diet cause numerous pathologies, including non-alcoholic fatty liver disease (NAFLD), high blood pressure, dyslipidemia, and peripheral insulin resistance. High energy diets also negatively impact the hippocampus, a brain area important for learning and memory. It is not surprising, then, that high energy diets impair hippocampal-dependent memory. The experiments in this dissertation investigate possible diet-induced consequences …
