The Impact Of Volume Of Tissue Activation On Cortical-Striatal Networks And Verbal Fluency Declines In Post-Deep Brain Stimulation Parkinson's Disease Patients., Alexander Luke Alley
The Impact Of Volume Of Tissue Activation On Cortical-Striatal Networks And Verbal Fluency Declines In Post-Deep Brain Stimulation Parkinson's Disease Patients., Alexander Luke Alley
Electronic Theses and Dissertations
This study investigated the cortical-striatal networks of verbal fluency declines in 6-month, post-operative, deep brain stimulation Parkinson’s Disease patients. Nine Parkinson’s disease participants with implanted STN or GPi DBS systems were recruited for this study. Verbal fluency data was obtained from each patient preoperatively and 6- months post implantation. The stimulation-based volume of tissue activated area (VTA) of each target site (STN or GPi) was analyzed using Lead-DBS and Lead-Group. The white matter tracks intersecting each patient’s VTA, terminating in the pre-SMA, SMA, caudate nucleus, and anterior cingulate were investigated and correlated with verbal fluency declines. We found statistically significant …
Bdnf-Related Gene Expression Of Laser Capture Microdissected Glutamate Neurons From The Anterior Cingulate Cortex In Mouse Models Of Autism Spectrum Disorder, Misty Owens
Electronic Theses and Dissertations
Autism spectrum disorder (ASD) is a neurodevelopmental disorder affecting social behaviors. ASD affects 1 in 59 children with males affected more frequently. ASD is postulated to result from excitatory and inhibitory neurotransmission imbalances. Brain-derived neurotrophic factor (BDNF) signaling affects ASD by influencing synaptogenesis, plasticity, and survival. Studying early in-utero neuropathological changes within ASD requires the use of animal models. Expression of BDNF-associated genes were analyzed within laser capture microdissected pyramidal neurons from the anterior cingulate cortex of male and female BTBR and valproic acid mouse models. No expression differences were found in any gene comparing the three groups. Gender comparisons …
A Protocol Driven Stroke Code's Impact On Door-To-Needle Times, Jesse Osborne
A Protocol Driven Stroke Code's Impact On Door-To-Needle Times, Jesse Osborne
Electronic Theses and Dissertations
Tissue plasminogen activator (tPA) is most effective the faster it is able to be administered to a patient that has been affected by stroke. A Stroke Code is a strategy that acute care facilities implement to reduce the time from diagnosing a stroke to administering tPA. The purpose of this study was to determine if the initiation of a Stroke Code in an acute care hospital reduces the door-to-needle time for patients affected by a stroke. In particular, does a Stroke Code reduce door-to-needle times. The research was conducted using data from April 1, 2014 to December 31, 2014 (pre-Stroke …
