Characterization Of Corticotropin Releasing Factor Receptor 2 In Stress-Regulating Regions Of The Mouse Brain, Jennifer J. Lafrican

Electronic Theses & Dissertations (2024 - present)

Sex differences in the morphology of the brain are thought to underlie the sex differences we see in anxiety and depression, where women are twice as likely to be diagnosed when compared to men. Stress, or a disruption to homeostasis, can exacerbate these mood disorders. Corticotropin releasing factor (CRF), and its receptors, play an important role in regulating the stress response. Binding of CRF with CRFR2 has been shown to reduce behavioral and neuroendocrine stress responses, yet whether there are sex differences in CRFR2 expressing neurons and stress-induced activation of these neurons in mice is unknown, in part due to …

The Menstrual Cycle, Dual-Hormone Hypothesis, And Competition: Implications For Athletic Performance, Camille Burns

Cal Poly Humboldt theses and projects

Female athletes perceive that the fluctuating hormones of the menstrual cycle affect their performance. However, research on objective performance is inconclusive, partly due to a lack of studies conducted in real-world competitive contexts. Testosterone is often seen to be elevated near ovulation and is related to social competitiveness. Under the dual-hormone hypothesis, testosterone only predicts competitive behavior when cortisol is low. The current study had two goals: (1) to test whether the dual-hormone hypothesis applied to competitive drive and objective athletic performance, and (2) to examine whether competitiveness and the intensity of one’s response to competition varied across the menstrual …
