谷氨酸及其受体与耳蜗神经元死亡的关系 e,Glu)作为耳蜗的传入神经递质,以L-Glu形式在毛细胞、听神经传入活动中起重要作用[1,2].当耳蜗内毛细胞(inner hair cell,IHC)释放Glu过多或再摄取不充分时,可导致以传入神经树突水肿为特征的兴奋性损害,伴大幅度听力下降,严重者

目的探讨庆大霉素对耳蜗内毛细胞带状突触数量的影响及其意义。
Objective To investigate the change of the ribbon synapses in inner hair cells by using gentamicin.
目的:建立耳蜗器官体外培养模型,观察缺氧对体外培养耳蜗内毛细胞(IHC)及外毛细胞(OHC)的影响。
Objective To establish a practical model for Wistar rat cochlea organ cultivated in vitro and observe the effect of hypoxia on the inner hair cells(IHC) and outer hair cells(OHC).
结果:给予万古霉素后的离体耳蜗内、外毛细胞未发生坏死和缺失,毛细胞密度与正常对照组无差别。
Results: There was no significant difference between the experimental group and the control on the density of hair cells.
On the top you see where the hair cells are located in the human cochlea.
幻灯上方显示的是,人耳蜗内毛细胞的位置。
There are only 12,000-15,000 in the human cochlea.
耳蜗内的毛细胞只有12000到15000个。
If these 8 million people , would correspond to the number of neurons in the brain, the equivalent of the hair cells that you could get out of a single cochlea would be equivalent to one person walking down 42nd street.
如果这八百万人,相当于大脑中的神经元数量的话,能从一个耳蜗内取出的毛细胞,就好比是,第42大街上的某位行人。
