Connections between the right and left cochlear nuclei were studied with retrograde and anterograde axonal transport techniques. Large, multipolar neurons in the anterior and posterior divisions of the anteroventral cochlear nucleus and in the posteroventral cochlear nucleus project to the ventral and dorsal cochlear nuclei on the opposite side. In addition, giant cells in the deep layers of the dorsal cochlear nucleus project to the contralateral posteroventral cochlear nucleus and possibly also to the contralateral dorsal cochlear nucleus. The pattern of terminal distribution of the crossed connections was determined by using the anterograde axonal transport of horseradish peroxidase-labelled wheat germ lectin. Although no part of the cochlear nuclear complex is completely free of anterograde label, the densest labelling is found in the anterior division of the anteroventral cochlear nucleus, throughout the posteroventral cochlear nucleus (where it is closely associated with cell bodies), and in the fusiform and superficial layers of the dorsal cochlear nucleus. These direct synaptic connections from one cochlear nucleus to the other could play a significant role in processes that depend on binaural interactions within the central nervous system.
采用逆行和顺行轴突运输技术研究了左右耳蜗核之间的联系。前腹侧耳蜗核的前、后亚核以及后腹侧耳蜗核中的大型多极神经元投射到对侧的腹侧和背侧耳蜗核。此外，背侧耳蜗核深层的巨细胞投射到对侧后腹侧耳蜗核，也可能投射到对侧背侧耳蜗核。通过使用辣根过氧化物酶标记的小麦胚凝集素的顺行轴突运输来确定交叉连接的终末分布模式。虽然耳蜗核复合体的任何部分都没有完全没有顺行标记，但在腹侧前耳蜗核的前亚核、整个后腹侧耳蜗核（与细胞体紧密相关）以及背侧耳蜗核的梭形层和浅层中发现了最密集的标记。从一个耳蜗核到另一个耳蜗核的这些直接突触连接可能在依赖于中枢神经系统内双耳相互作用的过程中发挥重要作用。
