Yet, these advancements risk exacerbating existing disparities in diagnosis and care. The 2024 Alzheimer's Association International Conference (AAIC) Advancements: Exploring Equity in Diagnosis convened interdisciplinary experts to address these inequities and chart a path toward population-generalizable research and practice. This article synthesizes key insights from the conference, highlighting considerations for inclusive and representative research design, ethical approaches in diagnostic disclosure, as well as challenges and solutions at individual, community, and systemic levels to advance …

Evidence For Direct And Sleep-Moderated Relationships Between Aquaporin-4 Genetic Variants And Alzheimer's Disease Phenotypes, Tenielle Porter, Ayeisha Milligan Armstrong, Eleanor K. O'Brien, Vincent Doré, Pierrick Bourgeat, Mitchell Turner, Paul Maruff, Christopher C. Rowe, Belinda M. Brown, Victor L. Villemagne, Stephanie R. Rainey-Smith, Simon M. Laws

Research outputs 2022 to 2026

Introduction: Variants in the aquaporin-4 gene (AQP4) have been associated with Alzheimer's disease (AD) diagnosis, cognition, and brain amyloid beta (Aβ) and may affect the sleep and Aβ relationship. Their association with other AD-related phenotypes/disease progression remain largely unknown. Methods: Associations between AQP4 variants, self-reported sleep measures, and AD-related phenotypes in cognitively unimpaired individuals with evidence of Aβ accumulation were examined using data from the Australian Imaging, Biomarkers and Lifestyle study. Results: AQP4 variants were directly associated with regional brain volumes, atrophy, and cognition. They were also associated with differences in regional brain volumes and atrophy in interaction with sleep …

Neuroscience Articles

BACKGROUND: Ocrelizumab is a humanised anti-CD20 monoclonal antibody approved for people with relapsing (RMS) or primary progressive multiple sclerosis (PPMS). In a post-hoc analysis of phase 3 trials in RMS and PPMS using a 600 mg dose, higher exposure to ocrelizumab was associated with greater B-cell depletion and lower risk of confirmed disability progression. Here, we prospectively assessed the efficacy and safety of a high dose of ocrelizumab in patients with RMS or PPMS.

METHODS: Two multicentre, double-blind, phase 3 controlled trials were conducted to compare high-dose ocrelizumab with the approved 600 mg dose of the drug in patients with …

Environmental And Pharmacological Modulation Of Opioid-Mediated Behavioral Effects In Rats, Corinne Ann Gallagher

Theses and Dissertations

Opioid Use Disorder (OUD) and opioid-associated overdoses continue to pose significant burden to US healthcare systems—both financially and in lives lost. It is imperative to identify risk factors which may predispose vulnerability to OUD development, which could aid in discovery of new therapeutic strategies for susceptible populations. This dissertation investigated the impacts of two such risk factors which modulate opioid-induced reward and behavioral effects: adolescent stress and the adulteration of illicit opioids by xylazine. In Chapter 2, we examined the effects of acute adolescent stress on oxycodone self-administration in rats, and the potential involvement of the locus coeruleus in these …

Foveate, Dahlia Aggarwal

Masters Theses

This thesis investigates how textiles can unsettle visual assumptions, encouraging a perceptual shift. Through weaving, upholstery, and spatial installation, the work stages a tension between what a surface appears to be and how it is encountered by the body. Through woven pattern, tactile texture, and trompe l’oeil textile surfaces, perception is something negotiated rather than fixed: the eye anticipates one reality while the hand discovers another.

Drawing on a range of sensations gathered from observing landscape formations and textures, it translates enduring scale and material qualities into an interior landscape of woven surfaces and textile-based furniture. Rather than serving as …

Local dendritic computations are thought to critically influence neuronal signaling and plasticity yet remain largely unexplored in vivo due to challenges in stably imaging small structures at ultrafast timescales. We developed a 3D real-time motion correction platform for movement-stabilized, ultrafast two-photon voltage imaging. By co-labeling CA1 pyramidal neurons with voltage and calcium indicators, we simultaneously measured somato-dendritic and electro-calcium coupling at multiple dendritic sites. We characterized isolated dendritic spikes and distance-dependent backpropagation of naturally occurring and photostimulation-evoked bursts and single spikes. We found that bursts backpropagated more reliably than single spikes, validated that somato-dendritic coupling decreases with distance from soma, …

Empowering Women: Understanding Neurological Changes In The Aging Brain, Joy Mckenzie

InnovateHER Meeting 2026

Women tend to have more neurological changes than men as they age starting in their mid-30s (Mosconi, 2024). While aging is a natural process, the neurological changes can impact a woman’s personal and professional quality of life (Faubion et al., 2023; Gravini, 2023). For years, women’s neurological symptoms have been ignored by being told that their experiences are normal and just a part of life (Haver, 2025). That narrative is starting to shift with the increased awareness of changes specific to women. There are resources to assess cognitive changes such as memory, processing speed, and word finding and strategies to …

In vivo microscopy (IVM) has shown great promise to improve early detection of epithelial precancer, but it suffers from fundamental trade-offs that limit the resolution, field-of-view (FOV) and depth-of-field (DOF). Here, we present PrecisionView, a compact, deep learning-enabled endomicroscope that breaks these constraints and achieves 20 mm2 FOV and 500 µm DOF with 4 µm resolution, representing approximately 5× increase in FOV and 8× larger DOF compared to conventional IVM with similar resolution. PrecisionView integrates a deep learning-optimized phase mask and real-time reconstruction, enabling rapid in vivo assessment of two key hallmarks of cancer: epithelial cell nuclear morphology and subsurface …

Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez

Psychology ETDs

Fetal Alcohol Spectrum Disorders involve morphologic and neurobiological abnormalities in offspring subjected to prenatal alcohol exposure. Although not as well studied as high exposure, moderate prenatal alcohol exposure represents the most common and undetected form in humans. While learning and memory deficits have been well characterized at the behavioral level in humans with Fetal Alcohol Spectrum Disorders and in animal models of moderate prenatal alcohol exposure, few studies have determined the circuit or systems level mechanisms of the behavioral deficits. A complete understanding of the neural bases of memory deficits after moderate prenatal alcohol exposure is needed to ultimately identify …

Brain-Based Mechanisms Of Behavioral Impairment In Fetal Alcohol Spectrum Disorder (Fasd): The Neuroimaging Biomarkers Of Inhibitory Control, Zinia Pervin

Biomedical Engineering ETDs

The developing brain is highly susceptible to alcohol-induced toxicity, often resulting in long-term deficits in executive function and behavioral regulation. Inhibitory control impairments are among the most prominent deficits observed in Fetal Alcohol Spectrum Disorder (FASD). This study investigated the neural mechanisms of inhibitory dysfunction using a multimodal MEG–DTI approach in 67 children aged 6–8 years (34 with FASD, 33 controls) who performed a Go/No-Go task. Source-level MEG analyses revealed reduced stimulus-locked cortical activation in the anterior cingulate cortex and significant group-by-hemisphere interactions in the superior parietal cortex and cuneus. Time–frequency analyses showed diminished response-locked beta power in the sensory-motor …

Birth Control Use Alters Memory For A Stressful Experience, Julia N. Gross, Kristie Payment, Boyd R. Rorabaugh, Phillip R. Zoladz

Aurora

Hormonal birth control methods are widely used; however, some users suffer considerable side effects. Previous research suggests oral contraceptive users exhibit a blunted cortisol response to psychosocial stressors and alterations in emotional memory, including differential recall of emotional images and details of emotional stories. However, no studies have examined how birth control influences memory for a stressful experience.

The present study analyzes data previously collected from female undergraduate students. In this study, participants reported contraceptive use, then underwent a modified version of the Trier Social Stress Test (TSST) or the friendly-TSST (f-TSST). The TSST required participants to deliver a ten-minute, …

Exploring The Biological Basis For Exercise Neuroprotection In Parkinson’S Disease: A Cross-Sectional Study Of Exercise And Physical Activity On Inflammatory Cytokines And Neurotrophins, Leah Isabelle P. Alegre, Jacob M. Brewer, Adeline Florschutz, Kate E. Hamiltonthompson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Regular exercise and physical therapy are known to increase production of neurotrophins, including brain-derived neurotrophic factor (BDNF), and anti-inflammatory cytokines. These changes combine to theoretically protect and slow the progressive loss of neurons in Parkinson’s disease (PD). The purpose of this study was to examine the effect of exercise and physical activity on various anti-inflammatory and pro-inflammatory cytokines and neurotrophins in people with PD (PwP). This was a cross-sectional design involving PwP (n=37), aged 43-85 years, who participated in two 30-minute bouts of exercise (with brief rest breaks during and pre/post blood draws) separated by a week. Measures collected prior …

Effectiveness Of Cognitive Stimulation Therapy On The Quality Of Life Of Adults With Dementia: A Secondary Analysis, Evelyn Airam

UNLV Theses, Dissertations, Professional Papers, and Capstones

This secondary analysis study evaluated the effectiveness of Cognitive Stimulation Therapy (CST) on quality of life (QoL), depressive symptoms, and cognitive function in 108 community-dwelling older adults with cognitive impairments, including dementia. Outcomes involved Quality of Life (QoL) measured by the Quality of Life in Alzheimer’s Disease (QoL-AD), symptoms of depression by the Cornell Scale for Depression in Dementia (CSDD), and cognitive function using the Saint Louis University Mental Status (SLUMS). After the CST, significant improvements were observed in QoL (p = .004), depressive symptoms (p = .002), and cognitive function (p < .001), with small effect sizes. Additionally, a significant interaction between sex and dementia diagnosis status was found in predicting cognitive changes, suggesting that the relationship between dementia diagnosis and cognitive improvement differs by sex. No between-group differences were found for QoL or depression. Findings support CST as a multidimensional, non-pharmacological intervention that improves cognitive, psychological, and social outcomes. Although effects were small, consistent improvements are clinically meaningful given the progressive nature of dementia. This study extends existing literature by demonstrating CST’s effectiveness in a community-based setting and reinforces its alignment with occupational therapy’s emphasis on participation and holistic care. Results highlight the need for early intervention and expanded access to CST programs to enhance quality of life in this population.

The Making Of An Extremist: How Do We Become Someone Else’S Nightmare?, María Paula Morales

The Confluence

This article explores how ordinary people can be pulled into extremist movements and what psychological forces drive that process. It looks at three perspectives: social identity theory, which explains how group belonging shapes behavior, identity development, which shows how people searching for meaning may find it in extremist causes; and social neuroscience, which connects radicalization to brain activity linked to fear, loyalty, and moral judgement. Together, these approaches show that radicalization is not simply about ideology but about identity, emotion, and belonging. By understanding these dynamics, we can find better ways to prevent extremism and promote healthier, more inclusive communities.

The Neurobiology Of Interruptions In Emergency Medicine: The Case For Informed Interruption Management In Support Of Cognitive Stability In High-Reliability Clinical Environments, James Espinosa, Henry Schuitema, Alan Lucerna

Rowan-Virtua Research Day

Background: Interruptions are ubiquitous in Emergency Departments (EDs) and have been associated with task delay, multitasking, and increased error risk. While operational and human-factors impacts are well described, the underlying neurocognitive mechanisms remain underexplored. Not all interruptions are avoidable.  However,  interruptions in emergency medicine represent neurocognitive destabilization events that can degrade task representation and increase vulnerability to error during task resumption. Recognizing the neural mechanisms underlying interruptions reframes their management as a systems-level patient safety priority. The aim is not elimination of clinically necessary communication, but thoughtful reduction, prioritization, and design that protects cognitive stability.

Objective: To synthesize cognitive neuroscience …

Procedural Narration As An Important Cognitive Adjunct To Analgesia: Naming And Neurobiologically Grounding An Established Emergency Medicine Practice, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: Experienced emergency physicians routinely provide real-time verbal guidance during procedures. Although widespread and intuitive, this practice has not been commonly conceptualized within pain neuroscience.

Objective: To name and mechanistically ground procedural narration as a form of cognitive analgesia, and to promote its intentional use and teaching in Emergency Medicine.

Methods: Narrative review integrating predictive coding theory, placebo/nocebo research, affective neuroscience, descending inhibitory pathway literature, and attentional modulation studies.

Results: Procedural narration reduces uncertainty, aligns expectation with sensation, modulates limbic threat processing, engages prefrontal cortical regulation, and supports descending inhibitory control of nociception.

Conclusion: Procedural narration is not a novel …

In School Age Children With Autism Spectrum Disorder, Does Academic Achievement And Social Development Improve In Inclusive Classroom Environments?, Ashley A. Macquaid

Rowan-Virtua Research Day

Autism Spectrum Disorder (ASD) is a developmental disorder characterized by difficulties in social skills, communication, and sensory processing 1. ASD affects approximately 1 in 100 children internationally 2. With the growing prevalence, classroom inclusivity of individuals with autism has emerged as a priority in education. However, current literature presents a range of positive and negative factors without clear indication of effective classroom placement for students' specific needs. This research aims to determine if inclusive classroom environments improve academic achievement and social development for school-age children with ASD. A systematic search on PubMed, Embase, and Cochrane databases yielded studies published between …

Adolescent Opioid Use And Prefrontal Cortex Development - A Systematic Review, Jonathan Perumpail, Liam Kerrick, Shreya Kadi

Rowan-Virtua Research Day

Adolescence represents a critical period of neurodevelopment characterized by ongoing maturation of the prefrontal cortex (PFC), a brain region essential for executive function, impulse control, and behavioral regulation. Exposure to opioids during this vulnerable window may disrupt neural development and lead to long-term consequences. This review synthesizes current preclinical and human evidence examining the effects of adolescent opioid exposure on PFC development. Across rodent models, opioid exposure is associated with impaired synaptogenesis, altered dopaminergic signaling, and dysregulation of the prefrontal-mesolimbic circuits involved in decision making. Human studies showed reduced functional connectivity and white matter changes in those with opioid use …

Young, Mikel Shea Ehntholt, Anuoluwapo Fadare, Jamie R. Feinour, Jennifer A. Jond, Jonathan Perumpail, Kevin Eaise, Lily Roessler, Shay Lynn Greco, Vanessa Salasky

Rowan-Virtua Research Day

Background. Neuro intensive care unit (ICU) patients often experience sleep deprivation due to serial neurologic assessments, among other factors. Subjective sleep disturbance has been associated with increased delirium risk in patients with intracerebral hemorrhage (ICH).¹ However, relationships between specific sleep features, delirium and subsequent outcomes in neurocritically ill patients have not been studied.¹ Additionally, ICH-related clinical research has not historically been conducted at Virtua Our Lady of Lourdes (VOLOL) Hospital. This study aimed to assess feasibility of obtaining quantitative sleep data, delirium assessments, and 90-day functional outcomes in neurocritical care patients with ICH.

Hypothesis. We hypothesized that 90-day …

Predicting Narcissism Through Social Media, Cameryn Freglette, Melanie Palomares

Caravel Undergraduate Research Journal

The objective of this study was to assess if narcissism can be predicted through social media behaviors such as frequency of posts, posting selfies, and social media presence on a variety of platforms. This study was conducted through a questionnaire related to social media use and a brief assessment from the Narcissistic Personality Inventory (NPI- 16). Results indicated that social media use per day was significantly different between people who post selfies and those who do not. Participants that scored higher for narcissism used social media less but posted significantly more selfies. Results were not significant in predicting narcissism through …

Heads Up! Designing A Nursing Assessment Tool For Early Recognition Of Intracranial Hypertension Post Head Injury, Sergio A. Dondiego

Honors Capstones

This meta-analysis identifies noninvasive clinical predictors of intracranial hypertension (IH) post head trauma to develop a multi-criteria IH screening tool designed for nurses to wear on their badge reels. High-sensitivity predictors were prioritized to assist in early IH suspicion. Findings suggest that radiographic-measured abnormalities including an optic nerve sheath diameter (ONSD) 5.6 mm and signs of significant head trauma via computed tomography (CT) were highly effective for predicting IH and were therefore defined as major criteria for the assessment tool. Other significant examination findings include a Glasgow Coma Scale (GCS) score 8 and atypical pupillary reactivity. While age showed conflicting …

Stromal Interaction Molecule (Stim) Proteins In Microglia And The Impact On Store-Operated Calcium Entry (Soce) And Spinal Cord Injury Recovery, Norah G. Hill

College of Arts & Sciences Senior Theses

In spinal cord injury (SCI), worsening functional outcomes are largely because of secondary injury processes and prolonged chronic inflammation. A major contributor of secondary injury is overload of intracellular calcium, causing neuronal overexcitation and persistent inflammatory responses. One of the primary mediators of calcium entry into the cell is store-operated calcium entry (SOCE). In SOCE, sensors detecting calcium depletion from the endoplasmic reticulum stores are called STIM proteins (1-2). When calcium is low in the cell, STIM proteins will activate Orai channels to open, allowing for the influx of calcium into the cell. The purpose of this study was to …

The Power Of Belief: Investigating The Intersection Of Religious Observance, Social Support, And Psychological Distress, Victoria R. Atwater

Undergraduate Honors Thesis Collection

Religion can act as a protective factor against stress and depression (Koenig et al., 2009; Krok, 2008) and can be examined through an individual’s relationship with religion or the efficacy of religious practices on mental health. In this study, 206 participants completed an online questionnaire that measured stress, depression, religious coping, religiosity (intrinsic religiosity, organized religious activities and non-organized religious activities), and social support using validated scales. The results indicate a positive correlation between stress, depression, and negative religious coping as predicted. While intrinsic religiosity and positive religious coping did not significantly influence stress or depression, organized religious activities were …

Targeting The Dorsolateral Prefrontal Cortex With Transcranial Direct Current Stimulation To Improve Depression And Anxiety In Parkinson's Disease, Brock Renicks

Honors Theses

The aim of this study is to observe the outcomes of transcranial direct current stimulation (tDCS) as a treatment for Parkinson’s Disease (PD). This study will primarily look at changes in depression and anxiety, as these symptoms are often comorbid with Parkinson’s Disease. Transcranial direct current stimulation is a non-invasive, very low-intensity form of electrical stimulation of the brain. It is being increasingly used as a form of treatment for Parkinson’s Disease and depression and anxiety, however the literature is ambiguous, showing mixed results throughout various studies, with no standardization of tDCS administration. To determine the effect of tDCS on …

Evaluating Spect Neuroimaging In Psychiatric Diagnosis: A Critical Review And Proposed Randomized Controlled Study, Kiley Carter

Senior Honors Theses

Mental illness affects a substantial proportion of adults in the United States, yet psychiatric diagnosis remains subject to diagnostic variability. Single-photon emission computed tomography (SPECT) is a neuroimaging technique that measures cerebral blood flow and has been proposed as an adjunctive tool for psychiatric evaluation. Existing literature reports group-level perfusion patterns associated with certain psychiatric conditions, suggesting potential utility in diagnosing complex or treatment-resistant cases. However, critics of SPECT emphasize the absence of randomized controlled data demonstrating improved patient outcomes. To address this gap, a prospective randomized controlled trial comparing standard psychiatric care with SPECT-guided evaluation is proposed. The proposed …

Targeting The Dorsolateral Prefrontal Cortex With Transcranial Direct Current Stimulation To Improve Depression And Anxiety In Parkinson’S Disease, Brock Renicks

Poster Presentations

Around 40% of people with Parkinson’s Disease experience depression and anxiety (Zhao et al, 2025). Depression and Anxiety have been said to be localized to the dorsolateral prefrontal cortex (Brunoni et al, 2016). Transcranial Direct current stimulation (tDCS) has been shown to modulate depression and anxiety by targeting the dorsolateral prefrontal cortex (Sreeraj et al, 2023). It is beneficial due to its cost, portability, and simplicity of use. Thus we will be assessing the efficacy of tDCS in reducing depression and anxiety in individuals with Parkinson’s Disease.
