The Effect Of Cerebellar Transcranial Direct Current Stimulation On Anxiety, Shivangi Bhardwaj Aug 2026

The Effect Of Cerebellar Transcranial Direct Current Stimulation On Anxiety, Shivangi Bhardwaj

All-Inclusive List of Electronic Theses and Dissertations

Anxiety is one of the most prevalent mental health disorders in the U.S. Individuals of all ages are affected by anxiety. Therefore, research into anxiety and its potential treatment has constantly been an area of interest. Newer approaches to managing anxiety include non-invasive stimulation techniques, such as Transcranial Direct Current Stimulation (tDCS), because of its accessibility and effectiveness. Past tDCS work typically focused on regions in the frontal lobe. However, tDCS over the cerebellum has not received as much attention compared to the cerebrum, despite recent work demonstrating cerebellar involvement in emotion processing. Thus, a better understanding of how cerebellar …


Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez May 2026

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 …


Targeting The Dorsolateral Prefrontal Cortex With Transcranial Direct Current Stimulation To Improve Depression And Anxiety In Parkinson's Disease, Brock Renicks May 2026

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 …

Eeg Signatures Of Motor Development In Early Childhood: A Systematic Review, Sonia Khurana, Ashwini Kulkarni, Thomas C. Bulea, Hunter J. Bennett

Rehabilitation Sciences Faculty Publications

Background

Early identification of motor developmental disorders is limited due to lack of objective neural markers that characterize typical neurodevelopmental patterns. This systematic review interprets and synthesizes existing evidence to propose a framework of EEG signatures associated with motor development in children aged 0-5 years, which may help inform future benchmarks for early assessment and intervention.

Methods

Following PRISMA guidelines, we searched published and gray literature across five databases between 2000 and 2025 (registered protocol). Included studies examined EEG during task-based, resting-state, or sleep studies linked to motor milestones, task performance, or standardized motor assessments. Study quality was assessed using …

Capacity, Allocation And Update Dynamics Of Human Memory Systems, Shaoying Wang Nov 2025

Capacity, Allocation And Update Dynamics Of Human Memory Systems, Shaoying Wang

Electronic Theses and Dissertations

Information is encoded and stored in three types of memory: sensory memory (SM), short-term memory (STM), and long-term memory (LTM). SM has a large capacity but retains information for only a brief period. When information transfers to STM, only a limited amount can be stored. Information in STM can then be transferred to LTM, which has a much larger capacity and longer retention time. STM is often conceptualized as working memory (WM) to highlight its role in active information processing. Due to the limited capacity of STM, it is commonly believed that STM serves as the bottleneck for information processing. …


Chronic Pain After Traumatic Brain Injury: Treatment Experiences And Effects On Cognition And Functioning, Rachael L. Snyder Aug 2025

Chronic Pain After Traumatic Brain Injury: Treatment Experiences And Effects On Cognition And Functioning, Rachael L. Snyder

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Traumatic brain injury (TBI) can contribute to changes in cognitive and emotional functioning, quality of life, and psychosocial reintegration. Chronic pain is a common consequence of TBI which can uniquely impact such outcomes. Still, the exact nature of the contribution of pain on post-TBI outcomes remains unclear, and there are few existing studies exploring the treatment journey for chronic pain and injury rehabilitation through qualitative methods, specifically individual interviews with TBI survivors. This study aimed to document these narratives and to identify precisely how the experiences of TBI survivors seeking treatments, rather than the treatments themselves, impact outcomes. It also …

Dystonia is a movement disorder with varied clinical features and diverse etiologies. Here we present a revision of the 2013 consensus definition and classification of dystonia in light of subsequent publications and experience with its application during the last decade. A panel of movement disorder specialists with expertise in dystonia reviewed the original document and proposed some revision. There was broad consensus to retain the definition of dystonia with only minor clarifications to the wording. Dystonia is defined as a movement disorder characterized by sustained or intermittent abnormal movements, postures, or both. Dystonic movements and postures are typically patterned and …

Brain and Mind Institute

The global prevalence of dementia is increasing. With no widely available and accessible treatments to halt or reverse the progression of dementia, exploring preventative strategies is critical. Lifestyle-based interventions show promise in preventing or delaying dementia onset. However, understanding the complex and multifactorial mechanisms underlying dementia, and how interventions target these pathways, is essential for developing personalized and effective strategies. In this review, we examined the current evidence of the mediating pathways in dementia risk reduction. We focused on mechanisms investigated in single-domain interventions on physical exercise, cognitive training, diet, metabolic/cardiovascular or psycho-social risk factors in line with those combined …

Task Demands Influence Search Strategy Selection In Otoconia-Deficient Mice, Ryan M. Yoder, Lucas C. Carstensen, Keshav Jagannathan

Psychology

Introduction: The vestibular system plays a crucial role in visual and non-visual navigation. Our recent study found that signals from the otolith organs are necessary for mice’s use of distal visual cues to guide navigation to an invisible goal. Somewhat surprisingly, however, performance was not significantly impaired on some spatial tasks (e.g., Barnes maze reference memory task), questioning the role of otolith signals in visual navigation.

Methods: We report the results of several additional tests of reference memory performance and search strategy use on two versions of the Barnes maze, in an attempt to establish further understanding of the otolithic …

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 …

Traumatic brain injury (TBI)-related growth hormone deficiency is often undertreated, despite documented physical, metabolic, and neuropsychiatric effects. Insulin-like growth factor (IGF-1), with neuroreceptors located in brain regions responsible for learning, memory, and mood, regulates cerebral blood flow, neurogenesis, and neuroplasticity. The aim of this study was to determine associations between IGF-1 levels and post-TBI symptom severity, anxiety, and depression. This retrospective observational study at an Academic Brain Injury Center included participants evaluated 3-12 months post-TBI with available IGF-1 values and complete Rivermead Post-Concussion Symptoms Questionnaire (RPQ-13), Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9) responses. Patients under 18 or …

Self-Harm In Female Youth With Undiagnosed Adhd: Implementing American Academy Of Pediatrics Screening Guidelines, Roselie M. Woodard

Dissertations

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. If undiagnosed or untreated, ADHD can lead to severe psychosocial issues such as academic failure, substance abuse, unplanned pregnancy, and incarceration. The financial burden in the U.S. from diagnostic errors creates an immense, rising fiscal impact. Early diagnosis and management are crucial to prevent these complications.

Females with ADHD, particularly those with the inattentive subtype, often face diagnostic challenges due to symptom masking and over-compensation. This results in poorer cognitive functioning and self-esteem compared to males with ADHD. ADHD is linked to autonomic nervous …

In precision medicine, both predicting the disease susceptibility of an individual and forecasting its disease-free survival are areas of key research. Besides the classical epidemiological predictor variables, data from multiple (omic) platforms are increasingly available. To integrate this wealth of information, we propose new methodology to combine both cooperative learning, a recent approach to leverage the predictive power of several datasets, and polygenic hazard score models. Polygenic hazard score models provide a practitioner with a more differentiated view of the predicted disease-free survival than the one given by merely a point estimate, for instance computed with a polygenic risk score. …

Bertolotti's syndrome, also known as lumbosacral transitional vertebrae, is a relatively rare spinal condition characterized by an anatomical variation in the lower spine. Conservative approaches such as physical therapy, anti-inflammatory medications and lifestyle modifications may be recommended for mild cases. In more severe cases or when conservative measures fail to provide relief, injections such as may be considered to alleviate pain. This case is unique in that we document a challenging technique of ipsilateral transforaminal epidural steroid injection in a patient with Bertolotti's syndrome.
