    • 2019, Bill Bryson, The Body: A Guide for Occupants, Black Swan (2020), page 79:
      These injuries, known as contrecoup injuries, appear on the opposite side of the brain from the point of impact because the brain is flung against its own protective (or in this case not-so-protective) casing.
