摘　　要：将辣根过氧化物酶(Horseradish peroxidase;HRP)分别电泳入大灰褐蝙蝠(Eptcsicusfuscus)和小灰褐蝙蝠(Myotis lucifugus)的小脑半球和蚓部对超声刺激有反应的记录点,以研究传递声信息到小脑去的有关神经结构。结果表明:小脑接受的主要声信息传入途径,是经过脑桥中转的;小脑也接受直接来自蜗核和上橄榄复合体的传入投射。此外,在下橄榄核和前庭核也发现标记细胞。Neural projections to the cerebellum of the bat, Myotis lucifugus and Eptesicus fu-souS, were studied by iontophoretic injection of horseradish peroxidase (HRP) into the cerebellar vermis and hemispheres. HRP was injected into the recording sites of cerebe-llar neurons responding to acoustic stimuli. The results showed that the cerebellm pri-marily received its auditory projections via the pontine nucleus. The cerebellum also received direct projections from the cochlear nucleus and superior olivary complex.HRP-labelled neurons were also found in the inferior olivary nucleus and vestibular nucleus.
