Meta-Analytic Connectivity Modelling Of Healthy Swallowing, Chris R. Tilton Jan 2023

Meta-Analytic Connectivity Modelling Of Healthy Swallowing, Chris R. Tilton

Honors Theses and Capstones

A quantitative, voxel-wise meta-analysis was performed to investigate the brain regions involved in healthy human swallowing. Studies included in the meta-analysis (1) examined water swallowing, saliva swallowing, or both, (2) included healthy, normal subjects, and (3) reported stereotaxic brain activation coordinates in standard space. Following these criteria, a systematic literature review identified 8 studies that met the criteria. An activation likelihood estimation (ALE) meta-analysis and meta-analytic connectivity modelling (MACM) analysis were performed with BrainMap software. Ten clusters with high activation likelihood were found in the bilateral precentral gyri, right insula, left declive, right medial frontal gyrus, right dorsal nucleus of …


Individual Behavioral And Neurobiological Markers Associated With A Vulnerable To Ethanol Use Phenotype, Kelsey M. Alimandi Jan 2023

Individual Behavioral And Neurobiological Markers Associated With A Vulnerable To Ethanol Use Phenotype, Kelsey M. Alimandi

Honors Theses and Capstones

Alcohol use disorder (AUD) is a chronic relapsing brain condition that is characterized by excessive alcohol consumption, continued use when faced with negative consequences, and a negative emotional state associated with withdrawals (anxiety, irritability, depression). The main challenge to treating AUD is preventing relapse. The purpose of this study was to use a prolonged-exposure model to allow rats to self-administer ethanol to determine the brain regions active during relapse events. The rats performed multiple behavioral tests such as economic demand, negative consequences, and an elevated plus maze. These tests determined how hard rats were willing to work for an ethanol …

The Possible Role Of Extra-Ocular Photoreceptors In The Entrainment Of Lobster Circadian Rhythms To Light:Dark Cycles, Sara A. Mckinney Apr 2013

The Possible Role Of Extra-Ocular Photoreceptors In The Entrainment Of Lobster Circadian Rhythms To Light:Dark Cycles, Sara A. Mckinney

Honors Theses and Capstones

The American lobster, Homarus americanus, is a decapod crustacean whose daily nocturnal rhythms of activity are driven, in part, by an internal biological clock. While this circadian clock is capable of producing a rhythm of approximately 24 hours on its own, it can also be entrained to light:dark cycles. Recent findings in our laboratory suggest that lobsters have photosensitive neurons throughout their nervous system (extra-ocular photoreceptors). The objective of this research was to test the hypothesis that these extra-ocular photoreceptors aid in entraining their daily rhythm of activity. First, the locomotion of juvenile American lobsters was measured in trials under …


Norepinephrine Involvement In The Intermittent Swim Stress-Induced Deficit In Spatial Learning And Memory, Emily Elgert Apr 2013

Norepinephrine Involvement In The Intermittent Swim Stress-Induced Deficit In Spatial Learning And Memory, Emily Elgert

Honors Theses and Capstones

Learning and memory impairments are often caused by stress disorders including depression. The present study investigated the involvement of norepinephrine in the swim stress-induced deficits of spatial learning and memory. Exposure to intermittent swim stress (ISS) followed by learning and memory tests in the Morris water maze (MWM) were used to investigate this relationship. The ISS paradigm consists of intermittent exposure to cold water, producing stress responses in rats. Reboxetine, a norepinephrine selective reuptake inhibitor (NSRI), was employed to investigate whether this compound reverses the ISS-induced deficit. In other words, rats exposed to the ISS, were hypothesized to experience impaired …
