Origins and terminations of fibers of the dorsal and intermediate acoustic striae were studied by surgically severing these tracts and injecting HRP into the incision. This procedure results in filling the severed axons with HRP. Filled axons were traced to cell groups of origin and to some terminations of the acoustic striae. HRP-labeled terminals were found in the cochlear nuclei as well as in periolivary cell groups. Filling of cells with HRP RANged from being complete, resulting in Golgi-like images, to being barely detectable. Labeled cells were abundant in the dorsal and posteroventral cochlear nucleus adjacent to the injection as well as scattered throughout the periolivary cell groups of both sides, being highest in concentration around the ipsilateral lateral superior olive. On the side contralateral to the injection, labeled cells were found along the medial border of the dorsal cochlear nucleus, in the interstitial nucleus of the stria of Held, and sparsely throughout the ventral cochlear nucleus. The distribution of labeled cells was similar following HRP injections of the dorsal cochlear nucleus, except that these injections revealed additional descending projections from the inferior colliculi and from the ventral nucleus of the trapezoid body of both sides. These additional projections were interpreted as entering the CN by a ventral route. Findings of this study are in accord with physiological recordings made from fibers of the acoustic striae.
通过手术切断背侧和中间听纹的纤维束并向切口中注入辣根过氧化物酶（HRP），研究了这些纤维束的起源和终止部位。该操作使切断的轴突充满HRP。充满HRP的轴突被追踪到起源细胞群和听纹的一些终止部位。在耳蜗核以及橄榄周细胞群中发现了HRP标记的终末。细胞被HRP填充的程度从完全填充（形成类似高尔基染色的图像）到几乎无法检测到不等。标记细胞在注射部位附近的背侧和后腹侧耳蜗核中丰富，并且散布在两侧的橄榄周细胞群中，在同侧外侧上橄榄周围浓度最高。在注射对侧，标记细胞沿背侧耳蜗核的内侧边界、赫尔德氏纹间质核以及稀疏地分布在腹侧耳蜗核中。在向背侧耳蜗核注射HRP后，标记细胞的分布相似，只是这些注射显示了来自两侧下丘和梯形体腹侧核的额外下行投射。这些额外的投射被解释为通过腹侧途径进入耳蜗核。本研究结果与从听纹纤维进行的生理记录一致。
