在理解神经控制扫视（当头部被阻止移动时进行的视觉定向运动）方面取得的进展主要源于早期的建模工作，它为开发和测试关于神经活动和观察行为之间关系的假设提供了框架。当头部可以自由移动时，视觉定位通常是通过眼睛和头部的协调运动来完成的。最近对这些运动的时间进展（即运动学）的描述导致了眼睛和头部控制信号相互作用的假设。这个假设现在被形式化为一个控制系统模型，它解释了现有的数据，并对定向凝视转移的神经控制做出了明确的预测。
Advances in understanding the neural control of saccades (visual orienting movements made when the head is prevented from moving) stem largely from early modeling efforts which provided a framework for developing and testing hypotheses about the relationships between neural activity and observed behaviors. When the head is free to move, visual orienting is often accomplished with coordinated movements of the eyes and head. A recent description of the temporal progression (i.e., kinematics) of these movements led to the hypothesis that eye and head control signals interact. This hypothesis is now formalized as a control systems model which accounts for existing data and makes explicit predictions about the neural control of orienting gaze shifts.
