Identifying Rna Splicing Changes During Alcohol Withdrawal Using An Optimized Rna-Seq Analysis Pipeline, Yasaswi Veera, Luana Martins De Carvalho, Amy Lasek

UROP Posters

Alcohol use disorder (AUD) causes long-lasting changes in brain gene expression and RNA splicing, particularly in the ventral hippocampus. This study analyzes RNA-Seq data from rats exposed to chronic alcohol and withdrawal to identify transcript-level and splicing alterations. An optimized RNA-Seq pipeline using STAR, FeatureCounts, edgeR, and WGCNA improved efficiency by 25-40% while maintaining consistency across 25 datasets. Results reveal changes in neural signaling and stress-response pathways associated with withdrawal. This work provides both biological insight into AUD and a reproducible computational framework for transcriptomic analysis.

Adaptive Evolution Of Learning And Memory In A Model Lineage, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Books and Book Chapters

Although reductionistic studies of mechanisms of learning in a broad range of model species have advanced our understanding of neural mechanisms, our integrated understanding of mechanisms, behavior, ecology, and evolution of learning remains patchy. A more wholistic research approach in a model lineage of species related to the sea hare, Aplysia californica, has revealed a complete loss of mechanisms of sensitization in one sea-hare genus, Dolabrifera, with concomitant changes in its behavior and ecology. A partial loss of sensitization via different mechanisms in a sister genus, Phyllaplysia, provides further information for our evolving understanding of the evolution of learning …

The Open Neuroscience Initiative is a free-to-use textbook

This project began as a means to overcoming the financial burden that face undergraduate neuroscience students when buying textbooks. By compiling and writing a completely free-to-access textbook that covers the foundations of a typical college introduction to neuroscience course, students would have one less obstacle to overcome in their educational career, allowing them to focus their valuable time and attention on learning rather than finances. To make this project a reality, I began with a humble tweet in May 2019 that managed to gain a tiny bit of traction among the neuroscience …

Axon Initial Segment Loss Is Not Observed In The Hippocampus Of A Experimental Autoimmune Encephalomyelitis Mouse Model, Praveen Mohanraju

UROP Posters

The axon initial segment (AIS) is fundamental for neuronal communication and action potential initiation, a characteristic which has been shown to be disrupted in inflammatory diseases such as Multiple Sclerosis (MS). Previous work from our lab has shown AIS breakdown in layer 5 of the cortex in a mouse model of MS known as experimental autoimmune encephalomyelitis (EAE). Moreover, it was shown that AIS breakdown was independent of demyelination but temporally correlated with microglial inflammatory reactivity. In order to determine if this pathology is specific to the cortex or affects other regions of the brain, we exploited these EAE induced …
