45POSTER 24ASSESSMENT OF A NOVEL PLR APP IN ADULTS VARYING IN AUTISTIC TRAITSALYSSA DESTEFANO (CUNY GRADUATE CENTER, COLLEGE OF STATEN ISLAND), CHLOE BRITTENHAM (ALBERT EINSTEIN COLLEGE OF MEDICINE), SAPIR SOKER-ELIMALIAH (UNIVERSITY OF SOUTHERN CALIFORNIA), LINDSAY HAYES (CUNY GRADUATE CENTER, KINGSBOROUGH COMMUNITY COLLEGE), JENNIFER WAGNER (COLLEGE OF STATEN ISLAND, CUNY GRADUATE CENTER) The pupil light response (PLR) has been found to be weaker in autistic individuals and non-autistic adults with high levels of autistic traits. This study utilizes a novel PLR app to assess the feasibility of using the app in place of lab-based measurements. Findings showed that app-based PLR metrics were also associated with variation in autistic traits, suggesting this as a useful tool for remote measurement of the PLR.POSTER 25ASSOCIATIONS BETWEEN GENERALIZED AND PREGNANCY-SPECIFIC MATERNAL ANXIETY SYMPTOMS AND INFANT BRAIN FUNCTIONANAHID AKBARYAN (NEW YORK UNIVERSITY GROSSMAN SCHOOL OF MEDICINE), NICOL%u00d2 PINI (COLUMBIA UNIVERSITY), LAUREN COSTELLO (NEW YORK UNIVERSITY GROSSMAN SCHOOL OF MEDICINE), JULIANNA COLLAZO VARGAS (NEW YORK UNIVERSITY GROSSMAN SCHOOL OF MEDICINE), ALLIE SAUL J. BERKOWITZ (NEW YORK UNIVERSITY GROSSMAN SCHOOL OF MEDICINE), ERIKA J. GARCIA (NEW YORK UNIVERSITY GROSSMAN SCHOOL OF MEDICINE), GABRIELLA RADICE (NEW YORK UNIVERSITY GROSSMAN SCHOOL OF MEDICINE), EMILY ODOM (NEW YORK UNIVERSITY GROSSMAN SCHOOL OF MEDICINE), LAUREN C. SHUFFREY (NEW YORK UNIVERSITY GROSSMAN SCHOOL OF MEDICINE) This analysis examines how generalized and pregnancy-specific maternal anxiety impacts infant brain function, measured by EEG power. Building on research linking maternal mental health to fetal brain development, this study isolates the unique effects of anxiety while controlling for depressive symptoms. Data from the ongoing DOLPHIN study will assess anxiety through questionnaires and analyze infant EEG power, hypothesizing that higher prenatal maternal anxiety symptoms are associated with greater right frontal asymmetry in infant brain activity.POSTER 26BALANCING ACT: ASSESSING THE RELATIONSHIP BETWEEN PERSONALITY AND BALANCEFAITH HUDNALL (MORGAN STATE UNIVERSITY), DAMON BRYANT (MORGAN STATE UNIVERSITY) Neurological disorders often disrupt proprioception, increasing fall risk. This study examines the relationship between proprioception and selfmonitoring (SM) through postural stability tests in college-aged students without neurological disorders. Proprioception is evaluated using the Modified Clinical Test for Sensory Interaction on Balance (mCTSIB), Limits of Stability (LOS), and the Balance Error Scoring System (BESS), alongside the Self-Monitoring Scale. We hypothesize that behaviorally variable high selfmonitors will exhibit superior postural stability. Findings may inform personalized rehabilitation strategies.POSTER 27CHEMOGENETIC INACTIVATION OF THE BASOLATERAL AMYGDALA ATTENUATES FEAR EXPRESSIONBRIGID BALDWIN (WASHINGTON COLLEGE), EMMALEE COLE (WASHINGTON COLLEGE), CAROLINE DRUPKA (WASHINGTON COLLEGE), GENEVIEVE KOZUB (WASHINGTON COLLEGE), BRYNN CASTELLANI (WASHINGTON COLLEGE), JUSTUS WILLIAMS (WASHINGTON COLLEGE), DANIEL KOCHLI (WASHINGTON COLLEGE) We investigated fear extinction by targeting the Basolateral Amygdala (BLA) via chemogenetic inhibition. We conducted fear conditioning training, extinction, extinction retention, and spontaneous recovery tests on rats. Rats that did not undergo chemogenetic inhibition exhibited reduced freezing during extinction, whereas inhibited rats had similar levels. Silencing the BLA significantly affected fear expression, highlighting its role in context fear learning.POSTER 28CONDITIONING PEOPLE TO PREFER VIRTUAL REALITY ROOMS WITH ALCOHOL CUESERIN CURRAN (UNIVERSITY OF CONNECTICUT), JUSTIN GUINTA (UNIVERSITY OF CONNECTICUT), NIKOLE RODRIGUEZ (UNIVERSITY OF CONNECTICUT), LILLIAN PERRY (UNIVERSITY OF CONNECTICUT), AVA WILLIAMS (UNIVERSITY OF CONNECTICUT), AISHWARYA BENZY (UNIVERSITY OF CONNECTICUT), SKYLER SKLENARIK (CENTRAL CONNECTICUT STATE UNIVERSITY), CHRIS BURROWS (UNIVERSITY OF CONNECTICUT), FINIAN ZAKAS (UNIVERSITY OF CONNECTICUT), ROBERT ASTUR (UNIVERSITY OF CONNECTICUT) Undergraduates were placed into a virtual world where one VR room contained alcohol stimuli while another 45Friday, March 7
