Cardiovascular reflexes and their roles in the neurohumeral control of the circulation have been investigated extensively. One reflex that has received very little attention is the vestibulosympathetic reflex. Despite the fact that the vestibular system has been shown to alter sympathetic outflow in animals, little is known about the vestibulosympathetic reflex and its function in humans. In this project, we plan to investigate the muscle sympathetic nerve activity responses to neck flexion, dynamic head movements and neck flexion in conjunction with other cardiovascular reflexes to better understand the vestibulosympathetic reflex.

心血管反射及其在循环的神经肱控制中的作用已被广泛研究。 前庭交感神经反射是一种很少受到注意的反射。 尽管前庭系统已被证明可以改变动物的交感神经流出，但人们对前庭交感神经反射及其在人类中的功能知之甚少。在这个项目中，我们计划调查肌肉交感神经活动的反应，颈部屈曲，动态头部运动和颈部屈曲与其他心血管反射，以更好地了解前庭交感神经反射。
