Mind-Reading Machine Can Visualize Your Memories

Scientists have discovered a way to reconstruct the images in a person's mind. In a new study, researchers concluded that it's possible to visualize a person's memory using only an fMRI machine and some machine learning software. For the study, published in the Journal of Neuroscience, the researchers showed 23 participants hundreds of faces while hooked up to an fMRI machine. While they were looking at the faces, an AI program was learning to associate their perception of certain features with different brain activity. Then, once the machine has learned which activity corresponds to which feature, the participants are shown a picture of a brand-new face, and the machine reconstructs it.
