自主的注视控制服从Listing定律。当已知眼睛的所谓"主要位置"时，该定律规定了眼睛在注视的每个方向上的扭转。在本文中，一些有趣的关系上市的法律和主要的立场，一方面，和眼肌神经支配的另一方面。一个新的矢量描述的眼睛的位置介绍，它允许代表上市的法律由一个非常简单的方程。它还允许近似眼肌神经支配和眼睛位置之间的转换，通过一个3 × 3矩阵在一个大的领域的凝视和神经支配的数量是直接相关的运动神经元放电率。结果表明，这些神经支配量必须线性耦合产生上市的法律，这种耦合的参数确定的主要位置。最后，神经支配和眼肌肉力量之间的关系被认为是，并提出了一个假设，自愿注视控制和耳石或聚散输入的合作。
Voluntary gaze control obeys the law of Listing. This law specifies the torsion of the eye in every direction of gaze, when the so-called “primary position” of the eye is known. In the present article, some interesting relations between Listing's Law and the primary position on the one hand, and eye muscle innervation on the other hand are derived. A new vectorial description of eye position is introduced which permits to represent Listing's Law by a very simple equation. It also allows to approximate the transformation between eye muscle innervation and eye position by a 3 x 3-matrix in a large field of gaze and with quantities of innervation which are directly related to motoneuron firing rates. It is shown that these innervation quantities must be linearly coupled to yield Listing's Law and that the parameters of this coupling determine the primary position. Finally, relations between innervations and eye muscle forces are considered, and a hypothesis concerning the co-operation of voluntary gaze control and otolith or vergence inputs is presented.
