摘要出于诊断目的,动眼神经反应最近引起了越来越多的关注。这与动眼系统是更简单的、类似机器的感觉运动系统之一的观点是一致的。本文提出了两个例子来证明感觉运动处理的复杂性可能比在相当有限的刺激条件下的实验结果所预期的要高。在第一部分中,表明包括视觉结构的空间梯度评估在内的复杂预处理是反射式眼跳编程的一个组成部分。第二部分涉及眼跳运动的适应性。数据表明,扫视增益控制对于扫视方向具有高度特异性。有人认为,由于特定适应机制的影响,许多中枢缺陷可能被隐藏。
SummaryThe oculomotor reactions have recently attracted increasing attention for diagnostic purposes. This is in line with the view that the oculomotor system is one of the simpler, machine-like sensorimotor systems. This paper presents two examples to demonstrate that the complexity of sensorimotor processing may be higher than expected from the outcome of experiments under rather restricted stimulus conditions. In the first part it is shown that complex preprocessing including the evaluation of spatial gradients of visual structure is an integral part of the programming of reflex-like saccades. The second part concerns adaptivity of saccadic eye movements. The data demonstrate that saccadic gain control is highly specific to the direction of the saccade. It is suggested that many central deficits may be hidden as a consequence of the effect of specific adaptive mechanisms.
