The Role Of The Progesterone Receptor In The Development Of The Ventromedial Nucleus And Female Sexual Behaviors, Keith L. Gonzales
The Role Of The Progesterone Receptor In The Development Of The Ventromedial Nucleus And Female Sexual Behaviors, Keith L. Gonzales
Legacy Theses & Dissertations (2009 - 2024)
Steroid induced gene transcription plays an important role in neural sex differences within many mammalian species. Steroid hormones actions within the developing brain have profound, permanent effects in the development of neurochemical processes and behaviors. Within the developing ventromedial nucleus of the hypothalamus (VMN), a potent transcription factor, the progesterone receptor (PR), is highly expressed within female rats. Furthermore, the regulation of PR within the developing VMN of the female rat is anatomically and developmentally specific. Typically, PR expression is highly dependent on the activity of estradiol acting at ERα. As such, circulating levels of estradiol act to induce PR …
Biological And Behavioral Correlates Among Young Adults Exposed To Harsh Parenting Practices, Christy Lyn Olezeski
Biological And Behavioral Correlates Among Young Adults Exposed To Harsh Parenting Practices, Christy Lyn Olezeski
Legacy Theses & Dissertations (2009 - 2024)
Whereas the subject of harsh parenting has been a source of debate for many years, research has shown that harsh parenting practices are associated with an increase in behavioral problems, including aggression toward others. However, not all youth who have been subjected to harsh parenting develop problems. Researchers have begun examining moderators of the effects of harsh parenting and other psychosocial stressors, specifically whether functioning in physiological stress response systems buffers or exacerbates the effects of harsh parenting on later functioning. Research also suggests that exposure to stressful situations (including harsh parenting) may affect the biological stress system. In particular, …
Effects Of Early Developmental Stress On Adult Physiology And Behavior, Michael James Frederick
Effects Of Early Developmental Stress On Adult Physiology And Behavior, Michael James Frederick
Legacy Theses & Dissertations (2009 - 2024)
Events during early development can have long-term effects on physiology and behavior. While extreme developmental stress is known to be associated with a variety of behavioral problems, it is less well understood how milder stress may affect behavior, personality, and reproductive success. This research project assessed a variety of behavioral dimensions in a college age sample, while assessing early development using size at birth, fluctuating asymmetry, and retrospective surveys. Maternal stress during pregnancy was found to reduce adolescent growth spurts and adult handgrip strength in the offspring. In males, lower birth weights were associated with higher scores of impulsivity and …
