Brain Fingerprinting

Brain fingerprinting is a controversial technique that is advocated as a way to identify a terrorist or other dangerous person by measuring the “brainprint” of that person when shown a particular body of writing or an image that was previously familiar (such as of a training camp or manual). The brainprint is based on the P300 complex, a series of well-known brainwave components that can be measured. The technique is said to be more effective than a lie detector test.

脑指纹

脑指纹是一项有争议的技术，被鼓吹用作识别恐怖分子或危险人物，它是通过向某人显示他熟悉的特别文章或图像（如训练营或手册上的内容）时测量他的“脑纹”。脑纹是基于P300复合体，即一系列著名的、可以测量的脑波成分。据说，该技术比测谎仪测试更有效。

用处

对自身来说呢，指纹可以把感觉到的冷、热、软、硬等各种“情报”通报拾大脑这个司令部，然后，大脑根据这些“情报”，发号施令，指挥动作。指纹还具有增强皮肤摩擦的作用，使手指能紧紧地握住东西，不易滑掉。其他的呢，还可以用在侦查、取证（刑事或按手印等），有的还用指纹制作鉴别设备用来防盗。
