Stimulation of the fastigial nuclei of the cerebellum was found to excite units located throughout the raphe nuclei of the brainstem. Raphe spinal units with axons conducting at velocities below 20 m/s were either unaffected by fastigial nucleus stimulation or inconsistently excited at long latency. In contrast units with faster conducting spinal axons throughout the raphe and more dorsally in the reticular formation were excited by stimulation of the fastigial nuclei. Many of these units responded at short latency and followed high rates of repetitive stimulation.
研究发现，刺激小脑顶核会兴奋位于整个脑干中缝核的神经元。轴突传导速度低于20米/秒的中缝脊髓神经元，要么不受顶核刺激的影响，要么在长潜伏期时受到不一致的兴奋。相比之下，中缝核中轴突传导速度更快且在网状结构中位置更靠背侧的神经元，会受到顶核刺激的兴奋。其中许多神经元在短潜伏期做出反应，并能跟随高频重复刺激。
