Do animals possess consciousness? Can consciousness be uploaded into a computer? Can we measure objectively whether someone is conscious or not?
Those may sound like deep, imponderable questions — but in a newly published book, “The Feeling of Life Itself,” neuroscientist Christof Koch actually lays out some answers: Yes, no … and yes, scientists are already testing a method for measuring consciousness, with eerie implications.
Along the way, Koch addresses brain-teasing concepts ranging from the Vulcan mind melds seen on “Star Trek” to the kind of brain-computer interface that billionaire Elon Musk is backing through his Neuralink venture.
