Graduate Theses and Dissertations
Inconsistent findings have been observed on the impact of hydration state on cognitive functions. The isolated effect of hypohydration on neurocognitive performance, balance, vestibular ocular motor function and mood outcomes in widely used concussion assessment tools has not been studied. The purpose of this study was to investigate how hypohydration affected the results in concussion testing batteries. A single-blind randomized crossover design was used. Thirteen healthy males (22 ± 4y, 180.9 ± 5.7cm) without history of concussion within the past six months or any condition or disease that could influence outcome measurements participated in this study. Each subject completed concussion …

Developmental dyslexia is a language learning disorder that affects a significant portion of the population. Many subjects who suffer from dyslexia show auditory processing deficits as children, some of which persist into adulthood, which impair their ability to learn one or more aspects of language. There is evidence that some types of training can correct the auditory processing deficits and bring the subject to a normal reading or speaking proficiency for their age group. One common rodent model for dyslexia is the cortical freeze lesion model. This model induces a lesion in the rat cortex similar to the microgyria present …

Diffusion weighted imaging (DWI) is a magnetic resonance imaging (MRI) method that produces in vivo images of biological tissues weighted with the local micro-structural characteristics of water diffusion. Diffusion tensor imaging (DTI), a form of DWI, is useful when a tissue, such as the neural axons of white matter in the brain, has an internal fibrous structure that allows water to diffuse more rapidly in alignment with the fibers. Changes in the water diffusion pattern indicate changes in the fiber structure which can result from damage to the fibers. Measurements of the water diffusion patterns include overall diffusivity, Apparent Diffusion …
