## Abstract ## Objectives/Hypothesis: Although precise localization of obstruction sites in the upper airway during sleep is essential in subjects with obstructive sleep apnea syndrome (OSAS), no gold standard diagnostic method has been established. This study aimed to evaluate the dynamic collaps

## Abstract ## Objectives/Hypothesis: To determine the dynamic characteristics of airway obstruction in subjects with obstructive sleep apnea (OSA) syndrome. ## Study Design: A prospective cohort study of 20 OSA patients and 19 control subjects who underwent realβtime magnetic resonance imaging
## Abstract In functional MRI experiments on the central auditory system, activation caused by acoustic scanner noise is a dominating factor that partially masks the hemodynamic response signals to sound stimuli of interest. In this study, the nonlinear interaction between auditory responses to sin
