Developmental Changes In The Activation And Structure Of The Contextual Fear Neural Circuit From Infancy To Adulthood, Anthony John Santarelli

Legacy Theses & Dissertations (2009 - 2024)

The contextual fear circuit, centered on the basolateral nucleus of the amygdala (BLA), is comprised of projections from the hippocampal formation and prefrontal cortex, and mediates an animals ability to learn and predict associations between the environment and biologically relevant stimuli. While the function and structure of this circuit has been well characterized in adult species, relatively little is known about its development as an animal transitions from infancy to adulthood. Recent evidence has begun to suggest that infants, juveniles, and adolescents may show remarkable heterogeneity in the behavioral, activational, and structural properties of the circuit. In this thesis, I …

Behavioral Impairment Following Gestational Exposure To Titanium Dioxide Nanomaterial Aerosols In Male And Female Rats, Matthew Leland Eckard

Graduate Theses, Dissertations, and Problem Reports

Engineered nanomaterials (ENMs) are beginning to be recognized as hazardous to human and animal health. Titanium dioxide (TiO2) is primarily used as a whitening agent in paints, plastics, and sunscreens. While relatively inert in its bulk form, nano-TiO2 (diameter) can produce prolonged inflammation and oxidative stress in target tissue. Recently, the potential for nano-TiO2 to cause neuroinflammation and damage has heightened concerns about its continued use. One important concern is that nano-TiO2, and other metal oxide ENMs, may affect fetal neurodevelopment. Accordingly, it is imperative to screen ENMs, like TiO2, for possible neurotoxicity following developmental exposures. The current set of …

Projected Sea Level Rise And The Conservation Ecology Of The Micronesian Megapode (Megapodius Laperouse Senex) In Palau, Micronesia, Paul M. Radley

Theses: Doctorates and Masters

Climate change has been a subject of numerous studies. While findings suggest that most biological taxa will be affected by its manifestations, aspects of a species life history may increase its susceptibility to climate change. Given their reliance on environmental sources of heat to incubate their eggs, I examined the vulnerability to climate change of the avian family Megapodiidae. I also assessed habitat use, susceptibility to sea level rise, and the effect of introduced rats and tourist presence, as added stressors to climate change, on the Micronesian Megapode (Megapodius

laperouse senex) in Palau.

Based on available literature, I …
