项目摘要
1) Experimental demonstration of the relation of spatial orientation to action controlDuring passive locomotion, the sensation and bodily balance of a driver are quite different from those of a passenger. Therefore, it seems likely that what the brain perceives determines the contents of sensation as well as action. The hypothesis was supported by the present experimental Coriolis stimulation, in which eye movements and bodily balance were recorded while a subejct was standing on a rotating platform.2) Production of an experimental device (rotating platform)Although tilting of a head during passive rotation produces curious eye movements and shifting of the center of pressure, it was hard to explain the phenomenon by a simple rule. In this study, we recorded eye movements and the center of pressure while subjects stood on a rotating platform. Recording was done under both visible and invisible conditions. Eye movements and bodily balance were equally influenced by the vector of the outer world in the brain which can be simply obtained by vector analysis.3) Proposal of a rule for passive and activ control of actionWhile rotating under an invisible condition, the space of outer world in the brain stays stationary since rotation is not perceived. When Corilois stimulation is given, the space in the brain is temporarily occupied by the vector from the labyrinth. As a result, curious eye movements and shift of bodily balance are produced. On the other hand, visible outer world rotates the space in the brain reversely. Although tilting of a head displaces the space in the brain, vestibular input by Corilois stimulation is added to the tilted coordinates in the brain. As a result, the space in the brain is preserved upright irrespective of head tilting.
1)空间定向与动作控制关系的实验验证在被动运动中,驾驶员的感觉和身体平衡与乘客的感觉和身体平衡有很大的不同。因此,似乎大脑所感知的东西决定了感觉和行动的内容。这一假设得到了本实验Coriolis刺激的支持,在该实验中,当受试者站在旋转平台上时记录眼球运动和身体平衡。2)实验装置(旋转平台)的制作虽然在被动旋转期间头部倾斜会产生奇怪的眼球运动和压力中心的转移,但很难用简单的规则来解释这种现象。在这项研究中,我们记录了受试者站在旋转平台上时的眼球运动和压力中心。记录是在可见和不可见的条件下进行的。3)提出了一种被动和主动控制动作的规则当在无形条件下旋转时,由于旋转是不可感知的,大脑中的外部世界空间保持静止。当给予Corilois刺激时,大脑中的空间暂时被来自迷宫的载体占据。因此,好奇的眼球运动和身体平衡的变化产生。另一方面,可见的外部世界使大脑中的空间旋转。虽然头部的倾斜使大脑中的空间移位,但是通过科里奥利刺激的前庭输入被添加到大脑中的倾斜坐标。因此,无论头部倾斜与否,大脑中的空间都保持直立。
