Vision could be fooled: disturbance of spatial perception by three dimensional visual stimulus

眩晕被认为是由前庭、视觉和躯体感觉输入不匹配引起的。我们发现，作为大脑高级视觉功能的MST区可以接收和整合前庭和视觉输入。MT区域只接收视觉输入。对于躯体感觉失配输入，我们评估了双耳低电流刺激下的步进模型。头部向前或向后弯曲，改变了半规管的位置，引起更严重的踏步水平偏差。只有一个不匹配的感觉可以打破整个空间感知。

The vertigo is thought to be caused by miss-match input of vestibular, visual, and somatic sensation. We revealed that the area MST, which was higher cerebral function of visual, received and integrated both vestibular and visual input. The area MT only received visual input. As to miss-match input of somatic sensation, we evaluated the model of stepping during low current electric stimulation between both ears. Forward or backward flexion of head, which changed the location of semicircular canals, induced more severe horizontal deviation of stepping. Only one miss-match sensation could break down the whole spatial perception.
