Abstract

A retrograde tracing study in the mole using wheat germ-agglutinated horseradish peroxidase (WGA-HRP) indicated that the medial superior olivary nucleus (MSO) projects to the inferior colliculus (IC) bilaterally. Considering the strict ipsilateral projections from the MSO to the IC in all other eutherian species ever reported, the bilateral projection in the mole is quite unique. This may reflect specializations of the peripheral auditory apparatus of the underground dwellers and/or primitiveness of the insectivorous brains.

摘要

一项使用小麦胚芽凝集辣根过氧化物酶（WGA-HRP）对鼹鼠进行的逆行追踪研究表明，内侧上橄榄核（MSO）双侧投射至下丘（IC）。鉴于在所有其他已报道的真兽类物种中，MSO到IC的投射都是严格的同侧投射，鼹鼠中的双侧投射相当独特。这可能反映了地下穴居动物外周听觉器官的特殊性和/或食虫类大脑的原始性。
