—This paper considers one type of common-mode feedback (CMFB) circuit that uses two differential pairs to sense the common-mode output voltage (V oc) of a fully differential op amp. Analysis of the circuit and simulation show that even powers of the differential-mode output voltage (V od) affect the common-mode control signal generated by the CMFB circuit.(More)
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)
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)
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)
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)
BACKGROUND AND OBJECTIVE Hypothermia has shown promise as a neuroprotective strategy for stroke. The use of whole body hypothermia has limited clinical utility due to many severe side effects. Selective brain cooling, or local brain hypothermia, has been previously proposed as an alternative treatment strategy. This study investigated the safety,(More)
OBJECTIVE The objectives of this study were, first, to explore differences in brain activity between normal people and idiopathic restless legs syndrome (RLS) patients during asymptomatic periods; and, second, to determine whether administering repetitive transcranial magnetic stimulation (rTMS) to specific cortical regions would reverse any observed(More)
