Using in vivo calcium imaging in a mouse model of neuropathic pain, the authors found a persistent increase in the activity of somatosensory cortex pyramidal neurons following peripheral nerve injury. Repeated pharmacogenetic activation of somatostatin-expressing inhibitory neurons after injury not only corrected this abnormal cortical activity but also prevented the development of chronic pain.
