据Jacobson J 2013年9月25日[Nat Neurosci,2013,16(9):1188-1190.]报道,在探寻虚拟环境时,人脑会呈现网格状活动。这表明,人身体内的导航系统即便在身体未发生物理空间意义上的移动时仍是活跃的。先前研究认为,动物对空间的感知源于被称为空间细胞(place cell)和网格细胞(grid cell)的两类神经细胞的作用,当动物进入 According to Jacobson J, September 25, 2013 [Nat Neurosci, 2013,16 (9): 1188-1190.] Reported that the human brain presents a grid-like activity when exploring the virtual environment. This shows that the navigation system in the human body is still active even in the absence of physical movements of the body. Previous studies suggested that the animal’s perception of space stems from the action of two types of nerve cells, called place cells and grid cells. When animals enter
