Symptom inventories are generally only collected after a suspected concussion, but regular in-season monitoring may allude to clinical symptoms associated with repetitive subconcussive impacts and potential undiagnosed concussions. Despite sex-specific differences in symptom presentation and outcome of concussion, no return-to-play protocol takes sex into account. The objective of this study was to monitor a cohort of contact-sport athletes and compare the frequency and severity of in-season concussion-like symptom reporting between sexes. Graded symptom checklists from 144 female and 104 male athlete-seasons were administered weekly to quantify the effect of subconcussive impacts on frequency and severity of in-season symptom reporting. In-season, …
Multiple Sclerosis And Its Symptom Management Through Supplementation And Dietary Planning, Lindsey J. Davis
Multiple Sclerosis And Its Symptom Management Through Supplementation And Dietary Planning, Lindsey J. Davis
Selected Honors Theses
Multiple Sclerosis (MS) is an autoimmune, neuroinflammatory disorder that is characterized by the breakdown of myelinated axons in the Central and Peripheral Nervous Systems. It is a potentially debilitating autoimmune disease that affects almost 1 million people in the United States, and nearly 2.5 million people worldwide. The precise etiology of MS is still being researched, but much progress has been made towards understanding the molecular mechanisms and impactful ways to treat this disease. While there is still no cure, new treatment plans are constantly being orchestrated in effort to alleviate the burden that MS carries. Combination treatment plans have …
Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass
Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass
Dissertations, Theses, and Capstone Projects
Traumatic brain injury (TBI) is one of the most common causes of death and disability worldwide, yet accurate in vivo detection of TBI neuropathology remains challenging due to complexities in the structural and functional changes observed post-injury as well as limitations in conventional neuroimaging modalities. Although advanced neuroimaging techniques such as arterial spin labeling (ASL) can noninvasively assess cerebral blood flow (CBF) changes observed post-injury, this technique is underutilized in TBI research partly due to the low signal-to-noise-ratio (SNR) inherent in ASL imaging. The aim of the current study is to examine the use of machine learning, specifically a Support …
Exploring The Usefulness Of Mindfulness Practices Through Zoom Meetings In Reducing Anxiety And/Or Stress Of Adults With Learning And Developmental Disabilities During The Covid-19 Pandemic, Thatiane Abra
Expressive Therapies Capstone Theses
This thesis explored which mindfulness meditations or mindfulness practices could be beneficial in the online sessions, the extent to which adults with learning and developmental disabilities could learn the practices remotely, and how stress and anxiety disorders could be reduced through online mindfulness interventions. Furthermore, it was also necessary to address the online sessions as the only mental health treatment possibility during the Coronavirus pandemic for the clients observed and the benefits and limitations of these interventions. Additionally, the importance of structure and routine for this population, the multi-modal structure of the interventions, and how attunement plays an important role …

In recent years, multivariate pattern analysis (MVPA) has been hugely beneficial for cognitive neuroscience by making new experiment designs possible and by increasing the inferential power of functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and other neuroimaging methodologies. In a similar time frame, “deep learning” (a term for the use of artificial neural networks with convolutional, recurrent, or similarly sophisticated architectures) has produced a parallel revolution in the field of machine learning and has been employed across a wide variety of applications. Traditional MVPA also uses a form of machine learning, but most commonly with much simpler techniques based on …

Standard magnetic resonance imaging approaches offer high-resolution but indirect measures of neural activity, limiting understanding of the physiological processes associated with imaging findings. Here, we used calibrated functional magnetic resonance imaging during the resting state to recover low-frequency fluctuations of the cerebral metabolic rate of oxygen (CMRO2). We tested whether functional connections derived from these fluctuations exhibited organization properties similar to those established by previous standard functional and anatomical connectivity studies. Seventeen participants underwent 20 min of resting imaging during dual-echo, pseudocontinuous arterial spin labeling, and blood-oxygen-level dependent (BOLD) signal acquisition. Participants also underwent a 10 min normocapnic and hypercapnic …
The Role Of Hamstring Contraction During Running: An Analysis, Theodore Hu
The Role Of Hamstring Contraction During Running: An Analysis, Theodore Hu
Senior Honors Theses
The hamstring muscle group, spanning the posterior aspect of the proximal lower limb, generates large amounts of contractile force during running. Researchers have examined this power generation within different phases of the stride cycle. Forces generated by the hamstrings hold implications for both running efficiency and the role of strengthening for injury prevention. The goal of this review is to examine the hamstring’s unique physiology as a bi-articular muscle, its role in running stride, various training philosophies, and the specific impact on running economy contributing to overall running performance. The summation of research presented shows that the hamstring muscle group …

Background: Alzheimer’s disease (AD) is generally thought to spare primary sensory function; however, such interpretations have drawn from a literature that has rarely taken into account the variable cognitive declines seen in patients with AD. As these cognitive domains are now known to modulate cortical somato-sensory processing, it remains possible that abnormalities in somatosensory function in patients with AD have been suppressed by neuropsychological variability in previous research. Methods: In this study, we combine magnetoencephalographic (MEG) brain imaging during a paired-pulse somatosensory gating task with an extensive battery of neuropsychological tests to investigate the influence of cognitive variability on estimated …
