Sensitization of pain pathways in the dorsal horn of the spinal cord leads to the emergence of hyperalgesia. Bonin and De Koninck now show that reactivation of sensitized pain pathways in mice with mechanical hyperalgesia renders them labile and enables the hyperalgesia to be reversed.

What are the safest painkillers?
