一直以来，神经科学家认为人脸识别（facial recognition）——人类大脑最高级的活动之一——是感性的且高度特异性（highly specific）的，无法轻易被重构和模仿（reconstruct and simulate）。传统的理论认为，我们日常的每一种意识体验、思维以及记忆，不管是对于某个亲戚朋友，还是其他任何人或者物，都只有特定的神经元与之对应。神经元以一种非常具体而明确的方式存储记忆的观点无疑十分浪漫，不乏情怀。然而加州理工大学的两名科学家最近的研究发现，人脸识别的过程实际上类似于计算机算法（alrithm）。在他们尝试将面部信息分解成两组各含25个度量标准（measurement）的数字时，结果发现计算机程序识别及重建的能力和人脑相差无二。

参考译文：大脑如何识别熟悉的长相这个难题可以回溯到20世纪60年代。当时美国的神经科学家杰瑞•莱特文提出，人类应对具体对象拥有高度特化的神经元。这个概念后来被称为“祖母细胞”，这基于一个观点：当见到祖母时，你的一个特定神经元会被激活。
