Hippocampal Connectivity In Parkinson's Disease, Landis Llewelyn
Honors Theses
Background: This thesis was conducted in order to investigate possible connections between functional connectivity of the hippocampus in individuals who have Parkinson’s disease.
Methods: The MRI images, the clinical data, and the demographic data of 93 individuals with PD and 18 individuals without PD were obtained from the Parkinson's Progression Markers Initiative. Resting-state fMRI data from a group of PD patients was compared to a control group of non-PD patients by using previously published methods with FMRIB Software Library (FSL) as well as Analysis of Functional Neuroimages (AFNI).
Results: Compared to the control (non-PD) group, results bilaterally showed lesser connectivity …
Verification And Quantification Of Surface Electromyographic (Emg) Activity Of The Masseter Muscle, Kelsey Bowles
Verification And Quantification Of Surface Electromyographic (Emg) Activity Of The Masseter Muscle, Kelsey Bowles
Honors Theses
Purpose: The goal of the present study is to develop and evaluate an automated technique for measuring biting and chewing related surface electromyographic (EMG) activity of the masseter muscle.
Methods: Data from 28 neurologically healthy participants between the ages of 18-40 were selected for this study. The procedure for collecting the bite/chew data consisted of the participant biting down and chewing three small breath mints while an EMG sensor recorded the masseter muscle activity. A five-step Matlab-based algorithm was created to accurately identify onsets and offsets of each bite and chew event.
Results: Compared to manual measurements using standard …
