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.

The capability of cocaine-associated stimuli in eliciting craving in human addicts, even after extended periods of abstinence, is modeled in animals using cue reinstatement of extinguished cocaine-seeking behavior. This study aimed to examine brain activation in response to cocaine cues in this model apart from activation produced by test novelty using a novel cue control. Rats trained to self-administer cocaine paired with either an oscillating light or tone cue underwent daily extinction training and were then tested for reinstatement of extinguished cocaine-seeking behavior elicited by response-contingent presentations of either their assigned cocaine-paired cue or the alternate, novel cue. Additional controls …

MicroRNAs are small, non-coding transcripts that post-transcriptionally regulate expression of multiple genes. Recently microRNAs have been linked to the etiology of neuropsychiatric disorders, including drug addiction. Following genome-wide sequence analyses, microRNA-495 (miR-495) was found to target several genes within the Knowledgebase of Addiction-Related Genes (KARG) database and to be highly expressed in the nucleus accumbens (NAc), a pivotal brain region involved in reward and motivation. The central hypothesis of this dissertation is that NAc miR-495 regulates drug abuse-related behavior by targeting several addiction-related genes (ARGs). I tested this hypothesis in two ways: 1) by examining the effects of viral-mediated miR-495 …
