Abstract

The intact and operated (unilateral cutting of utricular or saccular nerve branches) pigeons were exposed to rotations in the horizontal plane. The position of the pigeon with respect to the rotation axis was such that horizontal canal afferents were activated either separately or together with otolith afferents. The results of canal-otolith interaction did not depend directly on enhancement or diminishing of the otolith afferentation but rather on a relative amount of the otolith signal alterations from the two labyrinths. Any variations of the nystagmus duration (increasing or decreasing) could result from different changes of the otolith signals from the two labyrinths.

摘要

将完整的和经手术处理(单侧切断椭圆囊或球囊神经分支)的鸽子置于水平面上进行旋转。鸽子相对于旋转轴的位置使得水平半规管传入神经要么单独被激活,要么与耳石传入神经一起被激活。半规管 - 耳石相互作用的结果并不直接取决于耳石传入神经活动的增强或减弱,而是取决于来自两个迷路的耳石信号变化的相对量。眼震持续时间的任何变化(增加或减少)都可能源于来自两个迷路的耳石信号的不同变化。
