| 摘 要： | 本工作用不同运动图形分别同时刺激家兔左右眼，通过检测正常及单侧前庭迷路损伤后家兔的ＯＫＮ反应，证明在这种刺激情况下，正常家兔的眼动反应为交替的ＯＫＮ反应，为进一步探讨交替ＯＫＮ的控制机制及控制部位建立了动物模型。

| Abstract: | Optokinetic responses to two dichoptically presented grating moving in opposite directions were investigated in normal and unilateral labyrinthectomized rabbits. In normal rabbits, OKN took place alternately, while in unilateral labyrinthectomized rabbits, alternating OKN still took place only with some irregularity. These resultS indicatethat OKN in rabbit to dichoptic stimulation is alternately controlled by the velocity in formation .comimg from the left and the right eye, a fact suggesting that the.switching center of the control system locates somewhere behind the point of binocular summation inthe central nervous system. |
