Prenatal Stress Effects On Sex Differences In Recognition Memory And Synaptic Expression Of Ampa-Type Glutamate Receptors, Rumyr Sobrepena Apr 2025

Prenatal Stress Effects On Sex Differences In Recognition Memory And Synaptic Expression Of Ampa-Type Glutamate Receptors, Rumyr Sobrepena

Undergraduate Research and Engagement Symposium

Prenatal stress (PRS) increases the risk of cognitive deficits in male but not female offspring. This study investigates sex-specific effects of PRS on RNA editing, AMPA receptor expression, and dendritic spine density in the dorsal CA1 hippocampus—critical for memory. Behavioral assays revealed impaired recognition memory in PRS males only. We hypothesize that reduced RNA editing and synaptic AMPA receptor localization underlie these deficits. Through immunohistochemistry, confocal imaging, and qPCR, we will assess correlations between molecular alterations and cognition. Findings may uncover mechanisms of female resilience to PRS and identify targets for treating neurodevelopmental disorders marked by cognitive impairments.

Seasonal And Environmental Influences On Snake Captures In Northern Indiana, Skye La Rosa, Nicholas Sekits, Sara Ruane

Undergraduate Research and Engagement Symposium

Midwestern snake populations have been declining, yet, snakes are challenging to capture and study due to their cryptic nature. We examined how the time of sampling, coverboard type, and temperature influenced the capture rates and sizes of Common Gartersnakes (Thamnophis sirtalis) and Dekay’s Brownsnakes (Storeria dekayi). We deployed coverboards (rubber or carpet) at 20 sites across northern Indiana and found that T. sirtalis captures peaked in July and August, and both species had smaller sizes in August. Coverboard type had no significant effect. These findings provide insight into snake ecology, particularly seasonal patterns, and habitat preferences, informing future conservation efforts.
