Recent treatments for depression have expanded, increasing alternative treatments, and it is unknown which treatments have the largest impact on depression. This research was designed to examine the treatments of depression, with a focus on psychotherapy and contemporary treatments such as ketamine, psilocybin, and transcranial magnetic stimulation. A literature review was conducted to assess treatment outcomes and neuroplastic changes in these interventions, as well as combinations of the interventions. Data were evaluated …
Beyond Stabilization: Biological Healing, Structural Exclusion, And The Recovery Gap After Border-Fall Trauma At The U.S.-Mexico Border, Julia Robinson
Beyond Stabilization: Biological Healing, Structural Exclusion, And The Recovery Gap After Border-Fall Trauma At The U.S.-Mexico Border, Julia Robinson
Undergraduate Honors Theses
This honors thesis examines the biochemical, ethical, and public health consequences of insufficient post-operative follow-up care for undocumented immigrants injured in border falls. Discussing pathways of inflammation resolution, wound healing, and bone remodeling, this thesis argues that recovery depends on tightly regulated molecular and cellular processes that are highly vulnerable to disruption without continued monitoring and rehabilitation (Loi et al., 2016; Maruyama et al., 2020). When follow-up care is absent, these processes can be predicted to derail, leading to infection, impaired healing, and permanent disability (Chung & Sohn, 2025; Howard et al., 2020; Kruidenier et al., 2018). Framed through principles …

Lifestyle And Activity Patterns Of The Classic Period Maya From Chac Balam And San Juan, Ambergris Caye, Belize, Abigail L. Hornbeck
Lifestyle And Activity Patterns Of The Classic Period Maya From Chac Balam And San Juan, Ambergris Caye, Belize, Abigail L. Hornbeck
Honors Theses
Bioarchaeological research often uses skeletal remains to reconstruct patterns of activity and labor in past populations. This study examines potential sex-based differences in long bone morphology among individuals from the Classic Maya sites of Chac Balam and San Juan on Ambergris Caye, Belize. These coastal communities participated in maritime trade networks, and daily activities such as cargo transport, canoe travel, and fishing may have placed distinctive mechanical stresses on the skeleton. The goal of this study was to evaluate whether measurable differences in bone structure between males and females reflect differences in habitual activity patterns.
Two complementary methods were used …
Occupational Stressors And Health Impacts Among First Responders, Mason N. Roach
Occupational Stressors And Health Impacts Among First Responders, Mason N. Roach
Honors College Theses
The United States 911 emergency response system is an interconnected web of public services that seeks to provide its community with care, resources, and safety in times of need. However, the impact of this support on the employees providing the service often goes unnoticed. This review identifies and analyzes the unique strains on first responders' physical and mental health using the Job Demand-Control Model and the Allostatic Load Model. A review of available research literature supports the conclusion that occupational-related stress, including trauma exposure, shift work, poor leadership, and inadequate communication, can have long-lasting negative impacts on provider health.

From Fog To Function: An Occupational Therapist's Guide To Evaluating And Treating Cancer-Related Cognitive Impairments, Lauren E. Toner
Entry-Level Occupational Therapy Doctorate - Doctoral Capstone Symposium
Cancer – related cognitive impairment (CRCI) is a common side effect of cancer treatment that interferes with cancer survivors’ occupational performance, independence, and quality of life. Despite its high prevalence, CRCI remains under recognized and inconsistently addressed within oncology care. About 70% of individuals diagnosed with cancer report cognitive changes during or after treatment, yet many do not receive treatment. Occupational therapists are clinically trained to evaluate and treat functional cognition, activities of daily activities, instrumental activities of daily living, and client centered goals, positioning them as key providers in addressing CRCI. However, limited occupational therapy specific resources have hindered …

Department of Biomedical and Translational Sciences Faculty Publications
We report the first crystal structure of the telmisartan-tempol conjugate 2,2,6,6-tetramethyl-1-(λ'-oxidaneyl)piperidin-4-yl 4'-[(1,7'-dimethyl-2'-propyl-1H,3'H-[2,5'-bibenzo[d]imidazol]-3'-yl)methyl]-[1,1'-biphenyl]-2-carboxylate free radical (YK-4-250, C₄₂H₄₆N₅O₃), a dual-function inhibitor designed to target both the angiotensin II type 1 receptor (AT₁R) and reactive oxygen species (ROS). Structural analysis reveals a unique crystal architecture in which the nitroxide radical is stabilized within a sterically protected environment while preserving the telmisartan pharmacophore essential for high-affinity receptor antagonism. YK-4-250 is a novel small-molecule conjugate of telmisartan and tempol that incorporates a catalytic stabilized nitroxide radical and was rationally designed to mitigate gastrointestinal acute radiation syndrome (GI-ARS).

The Relationship Between Phone Usage, Activity Participation, And Hand Strength, Debra Gibbs, Will Best, Raegan Adams, Amanda Finke, Rachel Pierce, Salem Swallows, Alisha Yoo
SPARK Symposium Presentations
Smartphone use among university students in the United States is steadily increasing. Longer duration of smartphone use has been associated with increased risk of smartphone addiction, reduced musculoskeletal strength, and engagement in meaningful activities. While prior research has examined these variables separately, limited evidence exists on the associations between smartphone use, hand grip and pinch strength, and extracurricular and leisure activities among U.S. university students. To address this gap, a correlational study was conducted using the Spearman rank correlation to analyze the relationship between phone use, activity participation, and hand strength. A Qualtrics survey including demographic information, phone usage, and …

Startle Habituation And Vagally Mediated Heart Rate Variability Influence The Use Of Emotion Regulation Strategies, Xiao Yang, Fang Fang, Angela Ximena Babb
Startle Habituation And Vagally Mediated Heart Rate Variability Influence The Use Of Emotion Regulation Strategies, Xiao Yang, Fang Fang, Angela Ximena Babb
Psychology Faculty Publications
Emotion regulation refers to the processes through which people modulate their emotional experiences and expressions, and difficulties in these processes underpin many forms of psychopathology. According to the process model, emotion regulation encompasses five classes of strategies, commonly grouped into antecedent-focused strategies (e.g., cognitive reappraisal) and response-focused strategies (e.g., expressive suppression). These strategies involve both explicit and implicit processes, which can be objectively assessed using physiological indices. The present study examined the effects of startle habituation and vagally mediated heart rate variability (vmHRV) on the use of cognitive appraisal and suppression. Forty-nine college-aged participants were recruited, and their resting heart …

Introducing Neuro Sscial Work: A Brief Reflection On Neuroscience And The Profession, Priscila Llamosa
Social Work Faculty Publications
This reflection introduces and contextualizes the term Neuro Social Work, which I coin to name a specialized practice area at the intersection of social work, neuroscience, and neurodiversity. Drawing on my experience as a social work educator and practitioner, I discuss social work’s uneasy relationship with neuroscience, marked both by the opportunity to deepen our understanding of trauma, development, and healing, and by the risks of using brain‑based evidence to individualize structural harms or justify surveillance of marginalized communities. I outline, in broad strokes, what distinguishes Neuro Social Work from general neuroscience‑informed practice. The note is intended as a concept …
The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough
The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough
Senior Honors Theses
Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Enhancing Cataract Surgery Outcomes: Optimal Use Of Pre- And Post-Operative Eye Drops, Keith Skolnick M.D., Anu Valiaveedu
Mako: NSU Undergraduate Student Journal
Many preoperative and postoperative cataract patients struggle with comprehending the use of prescription medication as directed. Language barriers and low health literacy levels are major factors contributing to improper use of prescriptions. To increase patients comprehension, the Fort Lauderdale Eye Institute employed an educational intervention consisting of a live presentation and an instructional video. Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

Dermatoglyphic Fluctuating Asymmetry In Schizotypy, Marcus R. Thomas
All-Inclusive List of Electronic Theses and Dissertations
Schizotypy has been linked with many of the proposed endophenotypes of schizophrenia, but research is limited on the relationship between schizotypy and dermatoglyphic fluctuating asymmetry. The present study sought to examine relationships between schizotypy, dermatoglyphic fluctuating asymmetry, handedness, and season of birth. 146 undergraduate students were identified as schizotypes (n = 52) or controls (n = 94) based on the Multidimensional Schizotypy Scale and had their finger and palm prints collected along with completing additional measures of schizotypy and handedness. Schizotypes did not exhibit a greater degree of dermatoglyphic fluctuating asymmetry, negative schizotypy was associated with increased absolute finger ridge …

Field Journal: The Excluded Middle, Carrie E. Kouts
Masters Theses
What does it look like to engage with organisms and landscapes at the periphery of anthropocentric value structures? How does one break the internalized myth that the “built” environment is excluded from the natural world? When does a hyper-mobile and hyper-commodified society confront the exponential crisis of animal death? Within this series of journal entries, field notes, collection observations, weird prose, and sensory musings, one will find questions on the nature of being human and the complex narratives of care we encounter in a world shared with more-than-humans. Each handwritten vignette and photograph from daily life weaves a non-linear and …
Are Cycles Of Neural Activity The Algorithm Of The Brain?, Edwin Omondi Onyango
Are Cycles Of Neural Activity The Algorithm Of The Brain?, Edwin Omondi Onyango
Computer Science Senior Theses
We propose that precisely timed neural activity cycles can serve as structural primitives for memory and computation in a system that exhibits associative learning like the brain. Inspired by biologically grounded mechanisms such as calcium-dependent plasticity, spike-timing-dependent learning, and phase-sensitive excitability, we construct a spiking neural network model in which repeated temporal coincidences drive the formation of self-sustaining activity loops. These cycles, once formed, persist as dynamic memory traces: not stored as static weights, but as reverberating patterns that replay in time when these loops are restarted. We show that noise alone fails to induce stable structure, but even sparse, …
The Endocannabinoid System's Influence And Modulation Of Nociception, Doreen M. Flannery
The Endocannabinoid System's Influence And Modulation Of Nociception, Doreen M. Flannery
Honors Thesis
The anatomy and physiology of pain is a well-defined pathway where noxious stimuli is processed by different systems in the brain. The central research question of this review is how can we better understand the neurobiological effects pain has, and assess if there is therapeutic potential in using endocannabinoids to modulate these effects. Endocannabinoids are signaling molecules that play a key role at both the cellular and molecular level in modulating both acute and chronic pain by influencing different processes within each level that affect how the body responds to both internal and external stimuli. The endocannabinoid system is a …

Investigating Prefrontal Cortex Neuronal Signatures Of Opioid-Induced Risk-Taking Behavior, Cana Quave
Dissertations and Theses (Open Access)
Opioid use disorder occurs alongside impaired risk-related decision-making, but the underlying neural correlates are unclear. We developed an approach-avoidance conflict task using a modified conditioned place preference procedure to study neural signals of risky opioid seeking in the prefrontal cortex, a region implicated in executive decision-making. Following morphine conditioned place preference, rats underwent a conflict test in which fear-inducing cat odor was introduced in the previously drug-paired side of the apparatus. While the saline-exposed control group avoided cat odor, the morphine group included two subsets of rats that either maintained a preference for the paired side despite the presence of …
The Role Of Occupational Therapy In Bladder And Bowel Management For Individuals With Spinal Cord Injuries: An Educational Video Series, Julia Ryan
Student Capstone Papers
Occupational therapy (OT) practitioners are uniquely positioned to support individuals with spinal cord injury (SCI) in developing effective bowel and bladder management (BBM) routines. However, most existing literature approaches BBM from a medical perspective, offering limited guidance on how to translate occupation-based strategies into OT practice. This lack of discipline-specific resources contributes to reduced confidence among generalist practitioners and hinders the consistent implementation of BBM interventions across inpatient and community settings. To address this gap, a nine-part educational video series was developed to enhance OT practitioners’ knowledge, clinical reasoning, and confidence in delivering BBM interventions for clients with SCI. The …

The Role Of The Female Reproductive Cycle In Social Communication And Relevance To Mental Health, Julissa Amaro Castillo, Fernando Dominguez, Ariana Hinojosa, Giselle Padilla, Mario Gil
Research Symposium
The female reproductive cycle is characterized by fluctuating hormones, including estrogens and progesterone, that are involved in reproductive health; however, they have also been linked to disorders like Premenstrual syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), mood swings, depression and others. The goal of this study is to use the Syrian hamster (Mesocricetus auratus) as an animal model to examine the influence of the reproductive cycle and hormones on behavior. Scent-marking activity known as flank marking is exhibited by territorial or sociable animals. In essence, animals mark their territory or convey information such as reproductive status by rubbing their flanks or …

Effects Of Arginine-Vasopressin In The Brain On Cardiovascular Function In A Psychosocial Stress Animal Model, Esmeralda Lopez-Garcia, Ariana V. Hinojosa, Esperanza I. Alaniz, Fernando Dominguez, Giselle Padilla, Mario Gil
Research Symposium
Background: Psychosocial stress impacts cardiovascular health, increasing the risk of events like myocardial infarction (MI), stress cardiomyopathy, and neuropsychiatric disorders, including Major Depressive Disorder (MDD) and Anxiety. However, our understanding of the biological mechanisms that connect psychosocial stress with negative cardiovascular and psychological outcomes remains incomplete. Arginine-vasopressin (AVP) is linked to both mental and physical health by regulating social behavior, blood pressure, and anxiety-related behaviors. This study investigates the potential cardioprotective effects of the neuropeptide AVP, in an effort to generate evidence that it may strengthen heart function and lessen the severity of adverse cardiovascular events caused by stress, brain …

Exploring The Effects Of Serotonin And Ssris On The Neurological, Behavioral, And Cardiovascular Systems Under Induced Stress –Using The Animal Model Of The Syrian Hamster, Ariana V. Hinojosa, Esperanza I. Alaniz, Esmeralda Lopez-Garcia, Giselle Padilla, Fernando Dominquez, Mario Gil
Research Symposium
Background: Serotonin is a neurotransmitter that has been found to have a wide range of effects on not just the neuropsychological processes but has also been found to exert effects outside the central nervous system (CNS); regulating numerous biological processes, such as metabolism, gastrointestinal system, reproductive function, and even the cardiovascular system. However, there is still a limited understanding of how serotonin affects all these systems due to its complexity and ability to regulate homeostasis. This project aims to create a stronger foundation of knowledge about serotonin and its influence on the interaction between the CNS, behavior, and cardiac function …

Excitation And Polarization Of Isolated Neurons By High-Frequency Sine Waves For Temporal Interference Stimulation, Iurii Semenov, Vitalii Kim, Giedre Silkuniene, Andrei G. Pakhomov
Bioelectrics Publications
The capacity of temporal interference (TI) stimulation to target deep brain regions without affecting nearby surface electrodes remains uncertain. Using artifact-free optical recording, we compare excitation patterns and thresholds in hippocampal neurons stimulated by “pure” and amplitude-modulated sine waves, representing TI waveforms near electrodes and at the target, respectively. We show that pure 2- and 20-kHz sine waves induce repetitive firing at rates that increase up to 60–90 Hz with stronger electric fields. Beyond this limit, action potentials merge into sustained depolarization, resulting in an excitation block. Modulating the sine waves at 20 Hz aligns firing with amplitude “beats” and …

A Comparative Analysis Of Perineuronal Nets In Trout And Zebrafish Models, Adnan Alyan
Cal Poly Humboldt theses and projects
Perineuronal nets (PNNs) are specialized extracellular matrix structures that surround certain types of neurons in the central nervous system. Research from the past few decades has cemented PNNs as an integral player in the closure and onset of critical periods, memory modulation, and neural plasticity. These effects are thought to occur when PNNs form around a neuron and structurally stabilize its synaptic connections. PNNs have been directly linked to behavioral changes, making them of interest to psychologists as well as neuroscientists. Several PNN components, such as Hapln1 and aggrecan such as have been found in zebrafish, a teleost fish (Kang …
