Central processing of inertial sensory information about head attitude and motion in space is crucial for motor control. Vestibular signals are coded relative to a non-inertial system, the head, that is virtually continuously in motion. Evidence for transformation of vestibular signals from head-fixed sensory coordinates to gravity-centered coordinates have been provided by studies of the vestibulo-ocular reflex. The underlying central processing depends on otolith afferent information that needs to be resolved in terms of head translation related inertial forces and head attitude dependent pull of gravity. Theoretical solutions have been suggested, but experimental evidence is still scarce. It appears, along these lines, that gaze control systems are intimately linked to motor control of head attitude and posture.
对头部姿态和空间运动的惯性感觉信息进行中枢处理对于运动控制至关重要。前庭信号是相对于一个非惯性系统——头部进行编码的，而头部实际上几乎一直在运动。前庭眼反射的研究提供了前庭信号从头部固定的感觉坐标转换为以重力为中心的坐标的证据。潜在的中枢处理依赖于耳石传入信息，这些信息需要根据与头部平移相关的惯性力和与头部姿态相关的重力拉力来解析。虽然已经提出了理论解决方案，但实验证据仍然很少。沿着这些思路看来，注视控制系统与头部姿态和姿势的运动控制密切相关。
