Neuroscientists from the University of California, Berkeley have successfully decoded brain activity into audible sounds. This is effectively mind reading.
By recording nerve impulses from the auditory cortex, scientists were able to detect which word a subject was thinking about 80-90% of the time. Although a highly invasive procedure, the experiment rested on the assumption that the activation of nerves in the auditory cortex is identical or similar when a word is heard or processed, as when a subject simply thought about it. What will the future utilize such technology for? We can only imagine.
