通过观察山辣根过氧化物酶在蛙髓背核（DMN，耳蜗核的一种动物同属物）内的顺行和逆行转运模式，探讨了蛙髓背核的传入和输出神经支配模式。发现该结构向双侧投射到上橄榄核（SON）和中脑背侧被盖核，对侧投射到对侧DMN、外lemnicus核（LLN）和半圆环体（TS）。TS的终止位点局限于层核和主核。DMN依次接受这些结构的投射，TS和背被盖核除外。对同侧LLN和TS的投影不明显。除上述发现外，DMN， SON和TS的上升投影以及SON的离心投影都被发现是局部组织的。
The afferent and efferent innervation patterns of the frog dorsal medullary nucleus (DMN; anuran homolog of the cochlear nucleus) were examined by studying the anterograde and retrograde transport patterns of horseradish peroxidase injected focally into the nucleus. It was found that this structure projected bilaterally to the superior olivary nuclei (SON) and dorsal midbrain tegmental nuclei, and contralaterally to the opposite DMN, the lateral lemnicus nucleus (LLN) and the torus semicircularis (TS). The termination sites in the TS were restricted to the laminar and principal nuclei. The DMN in turn received projections from these structures with the exception of the TS and dorsal tegmental nuclei. The projection to the ipsilateral LLN and TS was not pronounced. In addition to the above findings, the ascending projection to the DMN, SON and TS, as well as the centrifugal projection from the SON, were found to be organized tonotopically.
