    A built-in 'off switch' to stop persistent pain   
      
   J. Nicholas Betley has led collaborative research seeking the neural   
   basis of long-term sustained pain and finds that a critical hub in the   
   brainstem holds a mechanism for stopping pain signals from reaching   
   the rest of the brain. Their findings could help clinicians better   
   understand chronic pain and lead to new, more efficacious treatments.
