Another controversial discussion point will be recent proof - of - concept work on how pictures of what's happening in the brain — functional magnetic resonance imaging (fMRI) or an EEG test (which captures electrical brain activity)-- could be coupled with computer algorithms to eventually reconstruct what a person saw or to capture other aspects of human perception.
