The medial amygdala (MeA) occupies a prominent role in the neurobehavioral transformation of sensory input into sexual behavior. A central aim in neuroscience is to understand the relationship between neural structure and behavior. Thus, I studied the relationship between mating…

Fetal alcohol spectrum disorder is the leading cause of mental retardation in the western world and is associated with numerous sensory processing deficits. Some of these deficits are a result of faulty neuronal plasticity. Previously our lab has used ferrets to demonstrate that…
Circadian disruption, specifically in shiftwork, entails significant health risks including metabolic and sleep-related disorders. Most current interventions involve the manipulation of the phase, or timing, of circadian rhythms, while those involving the waveform, or shape, of …
A system of constitutive equations is proposed that describes the viscoplastic behavior of a class of metal alloys when subjected to large deformations. The model is purely elastic before the plastic state is reached, and becomes elastic/viscoplastic after the plastic state has …
This thesis describes a non-linear finite element model suitable for the analysis of reinforced concrete, or steel, structures under general three-dimensional states of loading. The 20 noded isoparametric brick element has been used to model the concrete and reinforcing bars are…
The plane-strain compression is one of the most basic operations in metal forming and serves as a useful model for analyzing many forming processes. In this thesis, a numerical simulation procedure using the slip line field (SLF) method has been developed and applied to the anal…
Phenotypic plasticity, the capacity of individuals to respond to changing environments by modifying traits, is critically important in allowing biological innovation in the face of environmental change. My dissertation used the clown anemonefish (Amphiprion percula) study system…
The global extent of tropical dry forests has rapidly diminished in recent decades due to a variety of threats, largely from human activity. Efforts to restore these forests require understanding of the various modes of regeneration and how they are impacted across a range of di…
Although mental health is well defined by sources like the World Health Organization (2014), there is a dearth of reliable scales to measure mental healthiness. This research relies upon the work of early psychologists to describe healthy functioning. Theorists such as Freud (19…
In order to develop more effective rehabilitative therapies for stroke patients, we must understand what biological barriers limit functional recovery. Here we study functional recovery after stroke in the visual domain where recovery can be easily quantified with visual field t…
Adult neurogenesis is the most dramatic form of plasticity in the adult brain and may play a role in learning and memory, especially in perceptually difficult tasks in complex natural environments. New neurons appear only in a few regions of the adult mammalian brain and become …
Human biologists remain invested in the prospect of developing a ‘biocultural synthesis’. The primary concerns identified in major touchstones of this effort include the presentation of biological function in terms of social relations, understanding the role that humans play in …
This research explores the effects of processing history and compressive strain on a microstructurally flexible high entropy alloy (HEA), Fe42Mn28Co10Cr15Si5 (in at%) – named DP-5Si-HEA. The material was characterized by electron backscatter diffraction (EBSD), scanning electron…
Neural systems do not exist in stasis; rather the brain is composed of an ever-evolving ensemble of neural networks that are responsible for changes in behavior and cognition across the lifespan. However, our understanding of these processes in the field of developmental neuroim…
