Transcriptomic Landscape Of Mammalian Ventral Pallidum At Single-Cell Resolution, Lite Yang, Lisa Z Fang, Michelle R Lynch, Chang S Xu, Hannah J Hahm, Yufen Zhang, Monique R Heitmeier, Vincent D Costa, Vijay K Samineni, Meaghan C Creed

2020-Current year OA Pubs

The ventral pallidum (VP) is critical for motivated behaviors. While contemporary work has begun to elucidate the functional diversity of VP neurons, the molecular heterogeneity underlying this functional diversity remains incompletely understood. We used single-nucleus RNA sequencing and in situ hybridization to define the transcriptional taxonomy of VP cell types in mice, macaques, and baboons. We found transcriptional conservation between all three species, within the broader neurochemical cell types. Unique dopaminoceptive and cholinergic subclusters were identified and conserved across both primate species but had no homolog in mice. This harmonized consensus VP cellular atlas will pave the way for understanding …

Persons Or Human-Mimicking Robots? Implications Of Ai For Moral Status, Kate Burckle, Catherine Peters

Honors Thesis

Rapid progress in the field of Artificial Intelligence (AI), in which AI technologies can now perform human tasks, e.g. hold advanced conversations, cook, clean, and navigate harsh terrain, blurs the line between humans and robots. The emergence of advanced AI technologies suggests that AI programs may develop consciousness in the near future, prompting important questions: if AIs attain abilities to perform the same tasks and exercise capacities traditionally limited to humans, do they deserve similar moral status? If so, what treatment would we owe to them? Through examination of competing accounts of personhood and moral status, this paper seeks to …

Subcutaneous Electroencephalography Monitoring For People With Epilepsy And Intellectual Disability: Co-Production Workshops, Rohit Shankar

Key Epigenetic And Signaling Factors In The Formation And Maintenance Of The Blood-Brain Barrier, Jayanarayanan Sadanandan, Sithara Thomas, Iny Elizabeth Mathew, Zhen Huang, Spiros L Blackburn, Nitin Tandon, Hrishikesh Lokhande, Pierre D Mccrea, Emery H Bresnick, Pramod K Dash, Devin W Mcbride, Arif Harmanci, Lalit K Ahirwar, Dania Jose, Ari C Dienel, Hussein A Zeineddine, Sungha Hong, Peeyush Kumar T

Faculty, Staff and Student Publications

The blood-brain barrier (BBB) controls the movement of molecules into and out of the central nervous system (CNS). Since a functional BBB forms by mouse embryonic day E15.5, we reasoned that gene cohorts expressed in CNS endothelial cells (EC) at E13.5 contribute to BBB formation. In contrast, adult gene signatures reflect BBB maintenance mechanisms. Supporting this hypothesis, transcriptomic analysis revealed distinct cohorts of EC genes involved in BBB formation and maintenance. Here, we demonstrate that epigenetic regulator's histone deacetylase 2 (HDAC2) and polycomb repressive complex 2 (PRC2) control EC gene expression for BBB development and prevent Wnt/β-catenin (Wnt) target genes …

Constructing The Communal Body: Literary Topographies Of Underclass And Working-Class Neighborhoods In Modern Osaka (1933-1960), Ran Wei

Arts & Sciences Graduate Student Theses and Dissertations

When literary scholars examine narratives about Osaka, they have largely focused on the relationship between Osaka and Tokyo or the representations of Osaka in the national imagination. The approach tends to neglect the role that minority groups play in creating Osaka as a city of local cosmopolitanism. Centering on how Osaka writers have represented four underclass and working-class neighborhoods in the city, this dissertation scrutinizes how the narratives complicate the images of Osaka constructed by the national government and challenge the official narrative of a homogeneous Japan. Despite Osaka’s changing position within the nation-state, its importance as a home for …

Infant Mortality Data: Missing Pieces To Prevention In Lesotho, Jacinda Croissant

Master's Projects and Capstones

Lower-middle-income countries (LMICs) like Lesotho lack complete and quality infant mortality data. Without infant mortality data, it can be challenging to develop public health education, programming, and policies to address preventative infant deaths in specific populations (Rao et al., 2004). A literature review identified strategies to improve infant mortality data in LMICs. Through a community engagement model and digital storytelling, community members can gain awareness, begin an ongoing conversation about local public health issues, and participate in an improved data collection system.
