OBJECTIVE To investigate microstructural tissue changes of trigeminal nerve (TGN) in patients with unilateral trigeminal neuralgia (TN) by multiple diffusion metrics, and correlate the diffusion indexes with the clinical variables. METHODS 16 patients with TN and 6 healthy controls (HC) were recruited into our study. All participants were imaged with a(More)
Current methods for assessing the efficacy of treatments for Parkinson's disease (PD) rely on physician rated scores. These methods pose three major shortcomings: 1) the subjectivity of the assessments, 2) the lack of precision on the rating scale (6 discrete levels), and 3) the inability to assess symptoms except under very specific conditions and/or for(More)
Internal state as well as environmental conditions influence choice behavior. The neural circuits underpinning state-dependent behavior remain largely unknown. Carbon dioxide (CO2) is an important olfactory cue for many insects, including mosquitoes, flies, moths, and honeybees [1]. Concentrations of CO2 higher than 0.02% above atmospheric level trigger a(More)
The purpose of this study is to investigate whether spontaneous brain activity amplitude alteration occurs in RRMS by comparing appropriately processed fMRI data from subjects with RRMS and healthy controls. Resting-state fMRIs collected from thirty-five RRMS patients and thirty-five age and sex-matched normal controls were compared to investigate the ALFF(More)
Low voltage and low power are two key requirements for on-chip realization of wireless power and data telemetry for applications in biomedical sensor instrumentation. Batteryless operation and wireless telemetry facilitate robust, reliable, and longer lifetime of the implant unit. As an ongoing research work, this paper demonstrates a low-power low-voltage(More)
To further investigate and improve upon current stroke models in nonhuman primates, infarct size, neurologic function and survival were evaluated in two endovascular ischemic models in sixteen rhesus monkeys. The first method utilized a micro-catheter or an inflatable balloon to occlude the M1 segment in six monkeys. In the second model, an autologous clot(More)
The NSF-funded Northwest Distributed Computer Science Department (NW-DCSD) project brings together 24 multi-disciplinary faculty from 19 diverse colleges and universities in an effort to change the face of computing in the Pacific Northwest region of the United States. We offer an innovative and inclusive vision of computing in the 21st century and foster(More)
