我们实验室最近的研究一直致力于理解正常人对眼球运动的适应性控制能力。为了平稳的追求,不同的运动反应对相同的感觉刺激(水平目标运动)可以学习,存储和门控输入或输出,根据上下文(垂直眼睛位置)。水平的“开环”部分的动态特性,视差驱动的收敛眼运动是在自适应控制之下的。眼扭转也受自适应控制,包括扭转“斜视适应”和扭转与水平前庭-眼反射(VOR)交叉耦合。最后,猴子的动眼蚓损伤会导致双眼运动功能紊乱:在没有视差提示的情况下出现“偏视”,以及在一只眼睛前佩戴水平棱镜导致水平斜视对持续视差的适应能力下降。
Recent research from our laboratory has been directed at understanding the range of capabilities for adaptive control of eye movements in normal human subjects. For smooth pursuit, different motor responses to the same sensory stimulus (horizontal target motion) can be learned, stored and gated in or out, according to context (vertical eye position). The dynamic properties of the ‘open-loop’ portion of horizontal, disparity-driven vergence eye movements are under adaptive control. Eye torsion is also subject to adaptive control, including torsional ‘phoria adaptation’ and cross-coupling of torsion into the horizontal vestibulo-ocular reflex (VOR). Finally, lesions of the oculomotor vermis in monkeys produce disordered binocular ocular motor function: ‘esodeviations’ in the absence of disparity cues, and decreased adaptation of the horizontal phoria to a sustained disparity induced by wearing a horizontal prism in front of one eye.
