Cephalopod Consciousness On “Their Own Terms”: Who Are “They”?, Willa M. Lane, Victor Ajuwon, Nicola S. Clayton Nov 2025

Cephalopod Consciousness On “Their Own Terms”: Who Are “They”?, Willa M. Lane, Victor Ajuwon, Nicola S. Clayton

Animal Sentience

Mather’s call to consider cephalopods’ consciousness “on their own terms” raises the question of the extent to which cephalopods can be considered a homogenous group. While coloeoid cephalopods share traits that strongly distinguish them from other molluscs and invertebrates, they show vast ecological and morphological diversity, with implications for the design of empirical investigations of consciousness. Extending Mather’s argument, we apply Birch et al.’s (2020) five-dimensional model to compare octopus, cuttlefish, squid, and nautilus. This comparison shows that even within a graded rather than categorical framework, putative consciousness profiles depend on which taxa are included in discussions of “cephalopod consciousness.” …

Faculty Research 2025

Genomic studies of neurodevelopmental disorders (NDDs) have identified several relevant genomic variants. EBF3 is a gene with an excess of protein-coding de novo variants and underlies Hypotonia, Ataxia, and Delayed Development Syndrome. We previously identified noncoding de novo variants in an enhancer of EBF3 and further found enrichment of deletions of this enhancer in NDDs. In this study, we generated a novel mouse line that deletes the highly conserved, orthologous mouse region within the Rr169617 regulatory region, and characterized the molecular and phenotypic aspects of this mouse model. We found a deviation from Mendelian expectation (P=0.02) with significant depletion of …

The Potential Co-Occurrence Of Perfectionism, Food Insecurity, And Gpa With Orthorexia Nervosa Risk, Samantha Kay Gould Nov 2025

The Potential Co-Occurrence Of Perfectionism, Food Insecurity, And Gpa With Orthorexia Nervosa Risk, Samantha Kay Gould

Master's Theses

There are indeterminate risk, prevalence, and correlation data on orthorexia nervosa (ON) as shown by current literature on disordered eating (Rodgers et al., 2021). As a roughly defined disordered eating pattern, ON may be better understood after identifying associations among other attributes in a college student sample (Abdullah et al., 2020; Mavrandrea & Gonidakis, 2023; Parra-Fernández, 2019; Rogowska et al., 2021). A cooccurrence and influence of perfectionism, food insecurity, and grade point average (GPA) with ON risk was hypothesized since current literature suggests college students exhibit each of these characteristics independently (Abdullah et al., 2020; Ambwani et al., 2019; Caferoglu …

Fetal Microchimerism Of The Eye Lens, Jamie Moubarak Nov 2025

Fetal Microchimerism Of The Eye Lens, Jamie Moubarak

Electronic Theses and Dissertations

Fetal microchimerism (FMc) is the presence of a small fetal cell population in the mother, sometimes exhibiting stem cell–like properties. FMc has been observed within many placental mammal organs, except the eye. We used Yspecific PCR on genomic mouse DNA to test the hypothesis that fetal microchimerism can also be found in the lens. Of the parous females tested, we detected an Ssty2-specific amplicon in 83% (5/6) of samples and an Sry-specific amplicon in 2/4 samples. 100% (5/5) of non-age-matched parous females were positive for both primers. These results provide evidence that cells of fetal or placental origin …
