Thanks to an experiment to better understand brain structure and function, and how well brains of the deceased could help us test potential treatments for neurodegenerative diseases, we've accidentally entered a brave new world in which reanimated minds hooked up to machines and computers aren't nearly as impossible as we might like. What does that mean for the future of neurology and medical treatments? Are some of the studies we want to do even ethical? Do we really need to worry about science going too far, and is there really such a thing, especially if we have a chance to save lives and understand ourselves better than ever before?
