Origin and percentage of bilaterally projecting pontocerebellar neurons whose axons branch within the cerebellum and link the two cerebellar hemispheres were studied in cats using double retrograde fluorescent tracing and lesion techniques. These pontocerebellar neurons, which can be viewed as a separate component of the pontocerebellar system, account for 5-10% of the pontine neurons projecting to the lateral hemisphere. The system is mainly composed of neurons the axons of which recross within the cerebellum. The pontocerebellar interhemispheric system described here is likely to be the basis for the previously described intracerebellar commissural system. The bilateral distribution of these fibers may provide an important substrate for the coordination of bilaterally performed movements.
利用双逆行荧光追踪和损伤技术,在猫身上研究了轴突在小脑内分支并连接两个小脑半球的双侧投射脑桥小脑神经元的起源和比例。这些脑桥小脑神经元可被视为脑桥小脑系统的一个独立组成部分,占投射到外侧半球的脑桥神经元的5%-10%。该系统主要由轴突在小脑中再次交叉的神经元组成。这里描述的脑桥小脑半球间系统可能是先前描述的小脑内连合系统的基础。这些纤维的双侧分布可能为双侧运动的协调提供重要的基质。
