  • Scientists discovered a new way that neurons switch on pain.
  • This change happens after an injury to the body.
  • Active neurons release a signal outside the cell.
  • The signal makes nearby cells send pain messages.
  • In mice, extra signal made pain responses stronger.
  • When researchers removed the signal, mice felt less pain.
  • The mice still moved and sensed normally after removal.
  • The discovery could help safer pain medicines in future.
