The incidence of reciprocal synapses at the base of outer hair cells of the human organ of Corti was studied by electron-microscopic serial section reconstruction. Reciprocal synapses were found in each of six ears from five individuals. A total of 1,386 serial sections and the neural poles of 25 outer hair cells in two individuals were examined. Fourteen of the 25 outer hair cells (56%) possessed reciprocal synapses. The incidence of reciprocal synapses increased from the first to the third rows of outer hair cells, as determined by the percentage of outer hair cells and afferent nerve terminals of each row demonstrating reciprocal synapses and the average number of reciprocal synapses per hair cell in each row. Hair cells with reciprocal synapses had more afferent and fewer efferent terminals per hair cell than hair cells without reciprocal synapses.
通过电子显微镜连续切片重建技术，研究了人类柯蒂氏器外毛细胞基部相互突触的发生率。在来自五个个体的六只耳朵中均发现了相互突触。共检查了1386个连续切片以及两个个体中25个外毛细胞的神经极。25个外毛细胞中有14个（56%）具有相互突触。根据每行显示相互突触的外毛细胞和传入神经末梢的百分比以及每行每个毛细胞的相互突触平均数量来确定，相互突触的发生率从外毛细胞的第一排到第三排呈增加趋势。与没有相互突触的毛细胞相比，具有相互突触的毛细胞每个毛细胞的传入末梢更多，传出末梢更少。
