我们都有迷路的时候。幸运的是,动物大脑中帮助认路的特殊细胞如今首次在人类身上发现。动物使用3种类型的细胞来认路。它们面临一个特定方向时,方向细胞会得到激发。动物处于一个特定地点时,它的位置细胞会激发。而随着它四处活动,网格细胞会定期激发。科学家已经在人类身上发现了方向和位置细胞,但是网格细胞的存在只是在一些大脑扫描过程中才显露出 We all get lost. Fortunately, special cells in animal brains that help identify the pathways are now found in humans for the first time. Animals use three types of cells to recognize the path. When they face a particular direction, the direction of the cells will be stimulated. When the animal is in a particular place, its location will stimulate the cells. And as it moves around, the grid cells fire periodically. Scientists have found direction and location cells in humans, but the presence of grid cells is only revealed during some brain scans
