封面故事:空间记忆是人类认识世界和改造世界的基本认知能力,与我们的生活息息相关.无论是寻找常用的生活物件,如钥匙和手机,还是外出上班、购物和约会,都依赖我们对周围环境的记忆.同时,空间记忆特别是认知地图的学习能力对于精神分裂症和阿尔茨海默病的早期诊断和干预有重要意义.近40多年大量动物和人类的空间记忆实验研究取得了重大进展,然而对人类空间记忆的神经基础和环路机制理解目前还处于起步阶段.围绕空间记忆的核心问题“大脑如何表征周围环境”,本研究综述了基于脑成像和电生理技术开展的空间记忆研究.通过梳理以往研究中有关生物体在构建认知地图的神经结构和神经活动规律,提出了海马结构和新皮层对空间记忆的编码环路和表征机制,并在此基础上对未来研究进行了展望.

Cover Story:Spatial memory is one of basic cognitive abilities for human to explore the world. It is ubiquitous in our thinking and speaking about our living environment. We essentially rely on spatial knowledge about the external environment not only when finding the objects (e.g., keys and cell phones), but also when shopping, working or dating. Given that special memory plays fundamental and important roles in daily life, it is vital to characterize how the brain represents the environment. Using fMRI and electrophysiological techniques to date, many studies have investigated spatial memory processing and neural mechanisms of hippocampus formation and neocortex. In this review, we focus on the key questions about how the brain constructs the cognitive map and which neural circuits are involved for this processing. Future studies to explore neural basis of human spatial memory will need to be highly interdisciplinary and integrative, and may contribute to the diagnosis and intervention of cognitive disorders.
