But in a new study, researchers were able to pretty accurately sketch out the thoughts of participants simply by scanning their brains. The images were removed, and the computer program crawled their brain activity, attempting to re-create the face in their memory. They followed the participants’ brain activity as they looked at each image, mapping neural activity to a code of numbers that correspond to the characteristics of each face. The computer’s new sketch reflected the face processed in the earlier participant’s brain. The image on the left represents the brain visually processing each image while the brain on the right is the memory attempting to recreate the image.
