文 | 追问nextquestion 人脑如何测算时间呢？比如时钟滴答，我们可以通过时钟齿轮的震动来感受时间；或者昼夜交替，我们 通过日月移动感受时间——所谓的时间测量，似乎都来源于规律运动的外部事物产生的运动痕迹。 除此之外，有没有人脑内部的时间表征呢？这是一个回归到原点的神经科学思辨，可能也是理解人脑和 人工智能区别的一把钥匙。 神经科学家大卫·罗比（David Robbe）认为，我们并不依赖所谓"脑内时钟"，我们对时间的估计是通过 我们与周围世界（或我们内心世界）的互动以及我们的行为产生的。这来自于他自己的啮齿动物行为实 验，也基于他对法国哲学家亨利·柏格森*（Henri Bergson）的思想的重新审视。他将这些思想整理成了 一篇综述文章 "Lost in Time, Relocating the Perception of Duration Outside the Brain"（迷失在时间中：将 时间感知重新定位在大脑之外）发表在Neuroscience & Biobehavioral Reviews上[1]。 保罗：亨利·柏格森*（Henri Bergson）是谁？你为什么如此痴迷于他和他提出的思 ...
