Inactivation Of Nucleus Reuniens Impairs Spatial Memory In Mice, Miranda Schwabe
Inactivation Of Nucleus Reuniens Impairs Spatial Memory In Mice, Miranda Schwabe
Theses and Dissertations
Episodic memory is a complex process requiring input from several regions of the brain. Coordinated activity in the Dorsal Hippocampus (DH) and medial Prefrontal Cortex (mPFC) is required for episodic memory consolidation. Our laboratory demonstrated that simultaneous subthreshold chemogenetic inactivation of the dorsal hippocampus (DH) and medial prefrontal cortex (mPFC) impairs the consolidation of object placement (OP) and object recognition (OR) memory in female mice (Tuscher et al., 2018), suggesting that these two brain regions work in concert to promote memory consolidation. However, the mechanisms through which the DH and mPFC interact to promote memory consolidation remain poorly understood. A …
The Effects Of Activity-Based Anorexia On The Rewarding Properties Of Methamphetamine And Wheel Running, Rachael M. Langa
The Effects Of Activity-Based Anorexia On The Rewarding Properties Of Methamphetamine And Wheel Running, Rachael M. Langa
Theses and Dissertations
An activity-based anorexia (ABA) paradigm in adolescent female mice was used to explore whether anorexia affects circuits underlying reward. The ABA paradigm significantly enhanced methamphetamine-induced conditioned place preference (CPP), but not wheel-induced CPP. These results indicate that the ABA paradigm enhances the rewarding properties of methamphetamine, but not wheel running.
How Does Eye Movement Desensitization And Reprocessing (Emdr) Work? An Examination Of The Potential Mechanisms Of Action, Sara Forster
How Does Eye Movement Desensitization And Reprocessing (Emdr) Work? An Examination Of The Potential Mechanisms Of Action, Sara Forster
Theses and Dissertations
A mounting body of evidence suggests that Eye Movement Desensitization and Reprocessing therapy (EMDR) is successful in reducing the impact of posttraumatic symptoms. Although the exact mechanisms of action remain unknown, theories from the psychological to the neuroscientific continue to emerge, expand, and evolve. This study will examine four of the most prominent theories to date and weigh the evidence for and against each one. It will also review, compare, and contrast the theories, evaluate the research supporting each one, and propose the most likely explanation for EMDR's success given the state of the research. Neurobiological mechanisms and correlates as …
Transcriptomic Profiling Of Postmortem Prefrontal Cortex And Nucleus Accumbens From Chronic Alcohol Abusers., Eric S. Vornholt
Transcriptomic Profiling Of Postmortem Prefrontal Cortex And Nucleus Accumbens From Chronic Alcohol Abusers., Eric S. Vornholt
Theses and Dissertations
Alcohol use disorder (AUD) is a debilitating psychiatric illness that develops from a combination of genetic and environmental factors. While it is well documented that AUD is heritable, the shift from recreational alcohol use to abuse/dependence is poorly understood. In this dissertation, using postmortem brain tissue from individuals with alcohol dependence (AD), we profiled the genome-wide expression of circular RNA (circRNA), microRNA (miRNA), and messenger RNA (mRNA) to better understand the impact of gene expression on the development of AUD. To achieve this, we performed two independent studies that explore transcriptome differences between AD cases and controls. The first of …
