神经营养因子又具有促进听觉神经系统发育并维持其正常功能的作用，其作用贯穿于从听板形成直至Corti器毛细胞与传入、传出神经末梢纤维之间建立突触关系的全过程。

ResultsThere was no expression of Caspase-3 in group A. The expression of Caspase-3 in group C was decreased compared with that in group B（P＜0.01. In groups B and C, expansion and vacuolization of mitochondria, swollen neurons and apoptotic bodies appeared, which suggested that WBH could induce neuron injury, and the neuron injury in group C was more severe than that in group B.

结果A组大鼠海马区神经元无Caspase-3表达，B、C两组大鼠海马区神经元有Caspase-3表达，B组较C组Caspase-3表达平均灰度值减小。B、C两组大鼠海马神经元超微结构发生改变、细胞器水肿，部分线粒体空化，内质网稀疏，突触前膜、后膜结构不完整，可见自噬体结构；B组大鼠的神经元超微结构损害较C组轻。
