Vestibular compensation, i.e. recovery after unilateral labyrinthectomy (UL) in the lamprey (a lower vertebrate, Cyclostome), as well as different means of promoting the compensation, is described. UL results in a loss of equilibrium and rotation during swimming which is compensated in about 60 days. The deficit can, however, be immediately abolished by applying asymmetrical tonic visual or vestibular input (electrical stimulation of the optic or vestibular nerve, illumination of one eye, removal of one eye). In addition, asymmetrical visual input promotes plastic changes underlying the vestibular compensation. The compensation is discussed in relation to the neuronal network responsible for postural control in the lamprey and identified in our previous studies.
描述了七鳃鳗（一种低等脊椎动物，圆口纲）单侧迷路切除术后的前庭代偿，即恢复情况，以及促进代偿的不同方法。单侧迷路切除术会导致七鳃鳗游泳时失去平衡和旋转能力，这种能力在大约60天内会得到代偿。然而，通过施加不对称的紧张性视觉或前庭输入（对视神经或前庭神经进行电刺激、单眼照明、摘除一只眼睛），这种缺陷可以立即消除。此外，不对称的视觉输入会促进前庭代偿背后的可塑性变化。结合七鳃鳗中负责姿势控制的神经元网络对这种代偿进行了讨论，该神经元网络是我们之前的研究所确定的。
