'Mind-Reading' Technology Can Turn Brain Activity Into Images - ExtremeTech

While study participants were hooked up to the fMRI, the team at Radboud displayed photographs of individual humans and asked participants to study them closely. The information from the fMRI was fed into a powerful AI algorithm called a Generative Adversarial Network, or GAN. Based on the neurological data received, the GAN was able to construct photo-like images similar to those shown to the participants. While the visual stimuli and AI-constructed images aren't perfect matches--in one pair, a man ages a bit, while in another a woman goes from strawberry to bleach blonde--they're surprisingly close.
