观察了猴子脑桥中脑水平的各种被盖损伤对运动功能的影响。讨论了脑干单胺能机制的重要性。结果还显示了下降被盖红脑系统和红橄榄小脑回路在控制外周运动活动中的重要性。事实证明，与完全中断大脑脚水平的锥体系统相比，破坏感觉运动皮层是消除自发性或骆驼蓬碱引起的震颤更有效的方法。
The effect of various tegmentary lesions at the level of the pontomesenchphalon in monkeys on motor function was observed. The importance of the monoaminergic mechanisms of the brainstem is discussed. The results also show the importance of the descending tegmentary rubral system and the rubroolivocerebellar circuit in controlling peripheral motor activity. The destruction of the sensory motor cortex proves to be a more effective way of eliminating spontaneous or harmaline induced tremor than the complete interruption of the pyramidal system on the level of the cerebral peduncle.
