Abstract：
Humans\' sensory systems work synergistically to allow us to determine where our head and body are relative to the environment. To date, most research on this topic has focused on the visual and vestibular systems. There has been much less research on the contributions of interoceptive signals to spatial orientation, so the overall picture of how spatial orientation works is incomplete. This gap in the literature is especially problematic for aviation and spaceflight, where spatial disorientation is more likely to occur due to less common gravity conditions (i.e. microgravity and hypergravity) and can lead to fatal errors. In the present manuscript we review and summarize the current literature on this topic. Based upon the available evidence it would seem that interoceptive signals, particularly patterns of fluid/organ displacement, may play a role in sensing where our body is relative to the environment. More research utilizing experimentally induced perturbations to interoceptive receptors is needed before quantitative conclusions regarding the role of these interoceptive receptors can be drawn.
摘要：
人类的感官系统协同作用，使我们能够确定我们的头部和身体相对于环境的位置。迄今为止,关于这一主题的大多数研究都集中在视觉和前庭系统上。关于交互感受信号对空间定向的贡献的研究要少得多，所以空间定位是如何工作的整体图景是不完整的。文献中的这种差距对航空和航天来说尤其成问题，由于不太常见的重力条件（即微重力和超重力），空间迷失方向更容易发生，并且可能导致致命的错误。在本手稿中，我们回顾并总结了有关该主题的当前文献。根据现有证据，感觉信号，特别是流体/器官移位的模式，可能在感知我们的身体相对于环境的位置方面发挥作用。在得出有关这些感受性受体的作用的定量结论之前，需要进行更多利用实验诱导的对感受性受体的扰动的研究。
