Light microscopic autoradiography and electron microscopic autoradiography were used to study the distribution of label in the cochlear efferents following in vivo incubation with tritiated amino acids. Two basic patterns of labeling were observed. These patterns correspond closely to the lateral and medial superior olivary complex (SOC) olivocochlear systems identified by Warr and Guinan ('79, Brain Res. 173:152-155). Our electron microscopic observations suggest that, at least in the gerbil, the complete separation of outer hair cell (OHC) versus inner hair cell (IHC) efferent innervation proposed by these investigators based upon light microscopic data does not occur. Rather, our data suggest that while the lateral SOC system supplies endings only to the region under the IHC, the medial SOC system may supply endings beneath both the IHCs and OHCs.
利用光学显微镜放射自显影术和电子显微镜放射自显影术，研究了用氚标记氨基酸进行体内孵育后耳蜗传出纤维中标记物的分布情况。观察到两种基本的标记模式。这些模式与Warr和Guinan（《脑研究》，1979年，第173卷，第152 - 155页）所确定的外侧和内侧上橄榄复合体（SOC）橄榄耳蜗系统密切对应。我们的电子显微镜观察表明，至少在沙鼠中，这些研究者基于光学显微镜数据提出的外毛细胞（OHC）与内毛细胞（IHC）传出神经支配完全分离的情况并未发生。相反，我们的数据表明，虽然外侧SOC系统仅向IHC下方区域提供终末，但内侧SOC系统可能向IHC和OHC下方都提供终末。
