We Only Need Half a Brain

Did you know that we can thrive with only half a brain? Weird. The New Yorker has a wonderful article documenting the lives of patients who live through these hemispherectomies. The strangest thing is that no one knows how they do it:

When I asked the surgeons how it’s possible for people with half a brain to live, let alone have a life, each of them spoke about plasticity, flexibility, redundancy, and potential, and then they smiled and said the same thing: “We don’t really know.”
