10 Words Technology Borrowed from Nature

It can say “hey that’s interesting, turn up the volume on this pain information that’s coming in”, or it can say “turn down the volume on that and pay less attention to it”. In Linden’s book Touch: The Science of Hand, Heart, and Mind, he discusses how our perception of pain relies on the brain and how it processes information coming from the nervous system.
