Bilateral projections from the medial superior olivary nucleus to the inferior colliculus in the mole (Mogera robusta).
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.
