这台电脑正在学习读心

现代科技使神经科学家们窥探人脑，但是计算机可以读心吗？通过借助被称为脑电图（EEG）的设备，外加一些计算机的魔法，我们英勇的神经科学家们尝试窥探一位被试者的内心所想。

Scientists can record electrical signals from the brain using EEGs and attempt to decode what a person is seeing. By showing hundreds of pictures and capturing brain activity, researchers found a unique neural spike when viewing faces, called the N170. Machine learning helped spot patterns in noisy data, but real success required timing tricks and narrowing the choices. Mind reading by EEG is possible in simple cases, but current technology has significant constraints.
