Designs And Outcomes Of Transcranial Magnetic Stimulation (Tms) And Repetitive Transcranial Magnetic Stimulation (Rtms) Circuits, Daniel Senda
UNLV Theses, Dissertations, Professional Papers, and Capstones
This thesis reports the design and outcomes of several circuits intended for transcranial magnetic stimulation (TMS) and repetitive transcranial magnetic stimulation (rTMS) research. In simple terms, TMS circuits are composed of four main blocks: high voltage power source, energy storage bank, control switch, and coil. Each one of these blocks has characteristics that influence how well the circuit will perform for TMS procedures. A successful TMS research circuit must have the ability to emit controlled electromagnetic pulses through a coil connected to it. For the first block, voltages ranging from 50 V to 2 kV were used. In the second …
Axon Initial Segment Morphology Across Typical Cortical Development And In Mouse Models Of Neurodevelopmental Disorders With A High Incidence Of Epilepsy, Rachel Ali Rodriguez
Axon Initial Segment Morphology Across Typical Cortical Development And In Mouse Models Of Neurodevelopmental Disorders With A High Incidence Of Epilepsy, Rachel Ali Rodriguez
UNLV Theses, Dissertations, Professional Papers, and Capstones
Neurodevelopmental disorders (NDDs) are commonly associated with a high incidence of epileptic seizures which result from excessive firing of neurons. The axon initial segment (AIS) is a neuronal compartment essential for the control of activity patterns of neurons. The AIS undergoes important modifications during development, but the molecular mechanisms that affect the development, morphology, and protein composition of the AIS are still not well understood. We examined AIS morphology of medial prefrontal cortex (mPFC) pyramidal neurons in wildtype mice across development and in two mouse models of NDDs. Results indicate restructurings at the AIS during typical development, some of which …
Multiple Approaches To Auditory Rhythm: Development Of Sustained Musical Beat And The Relation To Language, Development Of Rhythmic Categories Via Iterated Production, And A Meta-Analytic Study Of Neural Entrainment To Beat, Karli Marie Nave
UNLV Theses, Dissertations, Professional Papers, and Capstones
Rhythm is ubiquitous to human communication, coordination, and experience of music. In this dissertation, I address three empirical questions through three different methodologies, all of which contribute to the growing body of literature on human auditory rhythm processing. In Chapter 2, I present a registered report detailing the results of independent conceptual replications of Nozaradan, Peretz, Missal, & Mouraux (2011), all using the same vetted protocol. Listeners performed the same tasks as in Nozaradan et al. (2011), with the addition of behavioral measures of perception. In neuroscience, neural correlates to musical beat perception have been identified, yet little to no …
Opioid And Naloxone Training In A Rural School District, Allyson C. Waldron
Opioid And Naloxone Training In A Rural School District, Allyson C. Waldron
UNLV Theses, Dissertations, Professional Papers, and Capstones
The opioid epidemic is a national health emergency in the United States, with over 128 people dying each day due to an opioid overdose. It is estimated that 4.3 million people over the age of 12 use opioids without a medical need, and 1.3 million youth ages 12-17 use opioids inappropriately. Drug overdose deaths have become the leading cause of accidental death in the United States, prompting the U.S. Surgeon General and the World Health Organization to advise that more Americans have access to naloxone and understand how to use this life-saving drug correctly. Naloxone is an opioid antagonist, used …
The Role Of Nutrition And Hormone Signaling In Extended Larval Development And Obesity In Starvation-Selected Drosophila Melanogaster, Jennifer M. Clark
The Role Of Nutrition And Hormone Signaling In Extended Larval Development And Obesity In Starvation-Selected Drosophila Melanogaster, Jennifer M. Clark
UNLV Theses, Dissertations, Professional Papers, and Capstones
Brief periods of starvation are a common stressor that most animals encounter in the wild and must be able to survive in order to maximize their fitness. Starvation resistance of the adult fruit fly, Drosophila melanogaster, is thought to be primarily conferred by adult fat stores, body size, metabolic rate, behavior, and activity levels. Additionally, flies selected for starvation resistance also often show delayed pupariation, which is usually indicative of altered hormone signaling. How starvation selection extends development and if it contributes to adult starvation resistance remains incompletely studied. Identifying the targets of starvation selection that cause extended development and …
Improving Self-Care Measures Of Hypertension Through Implementation Of An Education And Action Plan, Crystal Celeste Huffaker
Improving Self-Care Measures Of Hypertension Through Implementation Of An Education And Action Plan, Crystal Celeste Huffaker
UNLV Theses, Dissertations, Professional Papers, and Capstones
Hypertension (HTN) is a leading cause of morbidity and mortality worldwide and one of the most common conditions seen by primary care providers. Current clinical practice guidelines recommend lifestyle modifications for patients with elevated blood pressure (BP) and diagnosed HTN. Despite these recommendations, many patients diagnosed with HTN make insufficient modifications to their lifestyle. The purpose of this project was to determine the impact of implementing an education session, with development of a patient action plan, along with 4-week, 8-week, and 12-week follow-ups on the adoption of self-care measures for HTN. Participants had their BP, height, and weight measured along …
Development Of A Novel Cognitive-Motor Dual Task Assessment Battery In Neurodegenerative Disease, Jason Longhurst
Development Of A Novel Cognitive-Motor Dual Task Assessment Battery In Neurodegenerative Disease, Jason Longhurst
UNLV Theses, Dissertations, Professional Papers, and Capstones
Automaticity --- the ability to perform a task with directing attentional resources to its completion --- is commonly reduced among individuals with neurodegenerative diseases. These automaticity deficits result in impaired functional and daily activities and are sensitive to subtle, subclinical impairments. However, current measurement of automaticity by dual task paradigms is methodologically limited. In order to gain insight into the current state of the literature regarding cognitive-motor interference in symptomatic and prodromal neurodegenerative disease, the author of this dissertation conducted a scoping review (Chapter 1). To address the methodological limitations of current measurement of automaticity, a new measurement tool was …
