The doctor Sean Mackey , of the Stanford University School of Medicine , says that people have searched for a pain detector for a long time, so he hopes that this technology will meet that goal, in order to properly treat various diseases .

To train the computer, eight volunteers underwent brain scans , to observe their reactions when they were touched by hot objects in different degree.
