Half a Brain Is Enough: The Story of Nico “Some things we believe because, even though they seem impossible, someone we trust says that they are true. It’s like that with the little boy in Dr Antonio Battro’s book, Half a Brain is Enough: The Story of Nico. Nico has half a brain–and a complete mind. Battro is so expert and likable and forthright that you come away from his book not only knowing Nico’s story is true, but sharing his awe at that amazing fact.” JAMA
