空间导航是日常生活所必需的高级认知功能,参与空间导航的海马及内嗅皮层等脑区易受到老化的影响并导致结构萎缩或功能紊乱。早期研究多利用动物实验、纸笔测验、现实环境等实验范式考察老年人的空间导航老化特点。由于具有与现实环境相似的场景、兼容磁共振成像扫描以及导航者可以与场景交互等优点,虚拟现实技术被越来越多地被应用到空间导航的老化研究中,并进一步揭示了海马等内侧颞叶脑区在空间导航老化中的重要作用。

Spatial navigation is an essential high-level cognitive function in daily life. However, the involved brain regions such as hippocampus and entorhinal cortex are vulnerable to aging and result in structural atrophy and functional alterations. Using the experimental paradigms like animal experiments, pencil-paper tests, and real-world navigation, early studies explored the behavioral performance of spatial navigation in older adults. By virtue of having similar scenes with realistic environment, compatible with magnetic resonance imaging scanning, and navigator could have interactions with scenes, virtual reality is increasingly applied in the age-related spatial navigation research, revealing the important role of medial temporal cortex such as hippocampus in age-related spatial navigation studies.
