ASU Electronic Theses and Dissertations


This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at gradformat@asu.edu.


Each year, millions of aging women will experience menopause, a transition from reproductive capability to reproductive senescence. In women, this transition is characterized by depleted ovarian follicles, declines in levels of sex hormones, and a dysregulation of gonadotrophin feedback loops. Consequently, menopause is accompanied by hot flashes, urogenital atrophy, cognitive decline, and other symptoms that reduce quality of life. To ameliorate these negative consequences, estrogen-containing hormone therapy is prescribed. Findings from clinical and pre-clinical research studies suggest that menopausal hormone therapies can benefit memory and associated neural substrates. However, findings are variable, with some studies reporting null or even detrimental …

5-HT2A receptor (R) antagonists and 5-HT2CR agonists attenuate reinstatement of cocaine-seeking behavior (i.e., incentive motivation). 5-HT2Rs are distributed throughout the brain, primarily in regions involved in reward circuitry, including the prefrontal cortex (PFC), caudate putamen (CPu), and basolateral (BlA) and central (CeA) amygdala. Using animal models, we tested our hypotheses that 5-HT2ARs in the medial (m) PFC mediate the incentive motivational effects of cocaine and cocaine-paired cues; 5-HT2ARs and 5-HT2CRs interact to attenuate cocaine hyperlocomotion and functional neuronal activation (i.e, Fos protein); and 5-HT2CRs in the BlA mediate the incentive motivational effects of cocaine-paired cues and anxiety-like behavior, while 5-HT2CRs …

Patients with schizophrenia have deficits in sensorimotor gating, the ability to gate out irrelevant stimuli in order to attend to relevant stimuli. Prepulse inhibition (PPI) of the startle response is a reliable and valid model of sensorimotor gating across species. Repeated D2-like agonist treatment alleviates prior PPI deficits in rats, termed a PPI recovery, and is observable 28 days after treatment. The aim of the current project is to illuminate the underlying mechanism for this persistent change of behavior and determine the clinical relevance of repeated D2-like agonist treatment. Our results revealed a significant increase in Delta FosB, a transcription …
