外淋巴的流体动力学对频率选择的重要性已被广泛认知 ,但是有关外淋巴对流传导的生物物理学对代谢动力学的作用却知之甚少。通过使用人工机械电冲动产生装置 ,检测豚鼠在节律性呼吸运动及鼓膜张肌( TTM)自发收缩等情况下外淋巴液流动压和耳蜗微音电位 ( CM)的改变 ,研究外淋巴 The importance of the hydrodynamics of the perilymph to the frequency selection has been widely recognized, but the role of the biophysics of perilymph convection conduction on the metabolic dynamics is poorly understood. The changes of perilymph flow pressure and cochlear micropattern potential (CM) in guinea pigs under rhythmic respiratory motion and spontaneous contractions of tympanic membrane (TTM) were examined by using artificial mechanical impulse generator.
