famous experiments by neuroscientists Professors Roger Sperry and Michael Gazzaniga. Their studies answered a strange question – what would happen if you planted an instruction into a brain and somehow hid it from the narrator? Say, for example, you managed to insert the instruction WALK into a person’s mind. And that person started walking. Without the narrator telling the brain’s owner why they were walking, how would they explain what they were doing? Would they be like a zombie? Would they just shrug?
