Evaluation Of Prerequisite Discrimination Skills For Obtaining Assent From Individuals With Intellectual Disabilities: A Translational Study, Jessica J. Helen Detrick

Dissertations

Assent can be defined as an individual’s affirmative agreement to participate and should be obtained by those who cannot consent (i.e., children and adults deemed as “incapable”) when conducting research or providing services. Federal policies recommend considering age, maturity, and psychological state to determine if a participant can assent. Beyond these considerations, there is little guidance. However, practitioners and researchers still have an ethical obligation to obtain assent. Morris and colleagues (2021) conducted a literature review of assent procedures documented within behavior-analytic journals and found few studies. Of the procedures identified, many would likely be difficult to implement with participants …

Immune Modulation Affects Olfactory Glomerular Recovery In Zebrafish, Bonnie E. Ebendick

Dissertations

Adult zebrafish regenerate neurons throughout their lifetime and exhibit rapid recovery from neuronal damage with support from their immune system, making them an excellent model for studying neuroinflammation and brain repair mechanisms. When olfactory sensory neurons are lesioned, their cell death stimulates the immune system by activating microglia and other immune cells in the olfactory bulb, initiating tissue repair and neuronal replacement. This dissertation investigates how the immune system influences recovery from neuronal damage, testing the hypothesis that immune perturbation in zebrafish alters neural recovery.

To investigate the link between immune function and neuronal regeneration, zebrafish received a unilateral lesion …
