Can people be identified by their brainwaves?

With brainwaves, when we see an image or read a word, our brains react and start to process the signal. It seems that each individual’s response to the external stimulus is different and forms a unique pattern. Technically brainwaves are a type of neural oscillation, a pattern that is rhythmic or repetitive within the central nervous system. These signals can be observed via an electroencephalogram. Two researchers – Professor Sarah Laszlo and Professor Zhanpeng Jin have carried out studies where brainwaves have been mapped. In tests, the neuroscientists have mapped the brain activity of 50 subjects. For this task, each subject was fitted with an electroencephalogram headset. Each person then viewed a series of 500 images. The images were selected in order to create an emotional response. The picture range…
