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 …
Physiology Of Yawning : Proximate Mechanisms Supporting An Ultimate Function, Melanie Lee Shoup-Knox
Physiology Of Yawning : Proximate Mechanisms Supporting An Ultimate Function, Melanie Lee Shoup-Knox
Legacy Theses & Dissertations (2009 - 2024)
Recent research suggests that yawning functions to cool the brain during periods of mild hyperthermia. Evidence for this hypothesis is largely behavioral, and includes reports of increased yawning during increases in ambient temperature and times of stress as well as an amelioration of yawning upon nasal breathing and forehead cooling. Little research has been published on the physiological mechanisms supporting a brain cooling function, however. The current set of studies explores human and animal physiological parameters in search of evidence of brain cooling during yawning. In humans, heart rate, skin temperature, and skin conductance findings suggest that yawning involves an …
