Mice undergoing neuropathic pain induce anxiogenic-like effects and hypernociception in cagemates.

Rodents can recognize pain-related responses in conspecifics. Therefore, cohabitation with a conspecific animal with chronic pain can potentially promote a stressful situation, which can trigger behavioral changes such as anxiety and depression and alter nociceptive responses. In this study we investigated the effect of cohabitation with a mouse undergoing sciatic nerve constriction (neuropathic pain model).
