51POSTER 55SHOCKS & SHOTS: THE EFFECTS OF ADOLESCENT TRAUMA ON ADULTHOOD ALCOHOL CONSUMPTIONLOGAN KENNY (WASHINGTON COLLEGE), GRACE BROWN (WASHINGTON COLLEGE), CAROLINE DRUPKA (WASHINGTON COLLEGE), DANIEL KOCHLI (WASHINGTON COLLEGE), ELIZABETH YOST (WASHINGTON COLLEGE) The purpose of this experiment is to test how adolescent trauma in rats affects adulthood alcohol consumption. Stress Enhanced Fear Learning (SEFL) was used to induce trauma. AutoShaping, Novelty Suppressed Feeding, and Open Field tasks occur before the self-administration of alcohol period. Results found that SEFL effects were significant across conditions. Overall results indicated that the non-shocked rats consumed more alcohol than the shocked rats. Clinical Applications are discussed.POSTER 56THE EFFECT OF ACUTE STRESS AND ESTROGEN TREATMENT ON SPATIAL LEARNINGMARIAM USMAN (CHRISTOPHER NEWPORT UNIVERSITY), YASMIERE BURKE (CHRISTOPHER NEWPORT UNIVERSITY), OLGA LIPATOVA (CHRISTOPHER NEWPORT UNIVERSITY) The present experiment examined the interactive effects of acute restraint stress and estrogen treatment on ovariectomized (OVX) female rats' ability to acquire and retain spatial information using the Open-Field Tower Maze task. Stress was found to enhance the acquisition of hippocampus-dependent spatial learning in OVX-cholesterol rats but impair it in OVX-estrogen rats. Additionally, stress appeared to reduce the rate of re-acquisition during the 48-hour retention test, with no significant effects observed on long-term retention.POSTER 57THE EFFECTS OF A CHRONIC HIGH-FAT, HIGHSUGAR DIET ON DELAY DISCOUNTING.STEPHEN ROBERTSON (SUSQUEHANNA UNIVERSITY), SHANNON JEFFERIS (SUSQUEHANNA UNIVERSITY), ASH STRYKER (SUSQUEHANNA UNIVERSITY), TIMOTHY WOOD (SUSQUEHANNA UNIVERSITY) The current study examined the ability of a chronic high-fat, high-sugar diet to alter impulsivity as measured by a delay discounting task. Further, we gave a series of acute haloperidol (dopamine receptor antagonist) challenges to probe for diet induced changes in dopamine receptors. Data collection is currently underway; however, the collected data reveal that haloperidol shows a dose-dependent increase in delay discounting (increased impulsivity) %u2013 especially for male rats fed a high-fat, high-sugar diet.POSTER 58THE EFFECTS OF TAURINE AS AN ANTIDEPRESSANTEMMALEE COLE (WASHINGTON COLLEGE), GEN KOZUB (WASHINGTON COLLEGE), DAN KOCHLI (WASHINGTON COLLEGE) This study explores the effects of Taurine as an antidepressant in 16 Wistar Kyoto rats. Rats were placed into Taurine or Vehicle groups based on various conditions. Effects of taurine were assessed by conducting three behavioral tasks: the open field, theelevated plus maze, and the forced swim task. Data collection is in progress. Results will be used to see if taurine can be used as an antidepressant.POSTER 59THE RELATIONSHIP BETWEEN LIFESTYLE FACTORS AND HUMAN SPATIAL PATTERN SEPARATIONMIKAYLA GOMEZ (IONA UNIVERSITY), SARAH WONGGOODRICH (IONA UNIVERSITY) Hippocampal pattern separation, the ability to discriminate between similar events in memory, is a critical process for keeping our memories accurate and resilient against confusion. The current study examines the association between lifestyle factors (sleep, chronic stress, and physical activity) and spatial pattern separation performance in young adults. These study findings may further advance our limited understanding of how spatial pattern separation is regulated in humans.POSTER 60THE RELATIONSHIP BETWEEN SLEEPINESS, DOPAMINE, AND FOOD IMPULSIVITYRAE MEARS (UNIVERSITY OF MARY WASHINGTON), KATHERINE BLAIRE (UNIVERSITY OF MARY WASHINGTON), MARIA DUQUE (UNIVERSITY OF MARY WASHINGTON), DAYTON KEFFER (UNIVERSITY OF MARY WASHINGTON), SOFIA TAYLOR (UNIVERSITY OF MARY WASHINGTON), ALLY TINGEN (UNIVERSITY OF MARY WASHINGTON), HILARY STEBBINS (UNIVERSITY OF MARY WASHINGTON) This poster investigates the role of sleepiness and dopamine function (measured by spontaneous eye blink rate; sEBR), in impulsive action toward food stimuli.
