The authors describe an experimental study carried out on baboons. After unilateral vestibular neurectomy, the behaviour disorders on the one hand, and on the other, modifications and temporal development of reflex muotatic excitability of the spine using Hoffmann's reflex method are analyzed. As far as behaviour is concerned, a four-day period of motor restriction following the operation causes more marked residual disorders in comparison with controls. From the neurophysiological point of view, neurectomy results in seriously disordered spinal reflexes characterized by ipsilateral hypo-excitability developing in there stages: a tw-day initial critical phase during which the disorders are at their worst, a four-day recuperative stage with partial regression of the disorders, finally a chronic compensation stage in which spinal excitability returns to normal after several months.
作者描述了一项在狒狒身上进行的实验研究。在单侧前庭神经切除术后，一方面分析行为障碍，另一方面使用霍夫曼反射法分析脊柱反射性肌紧张兴奋性的变化及其时间发展。就行为而言，与对照组相比，术后为期四天的运动限制期会导致更明显的残留障碍。从神经生理学角度来看，神经切除术导致严重紊乱的脊髓反射，其特征是同侧兴奋性降低，发展过程分为三个阶段：为期两天的初始关键期，在此期间紊乱最为严重；为期四天的恢复阶段，紊乱部分消退；最后是慢性代偿阶段，几个月后脊髓兴奋性恢复正常。
