We can't live without it, but many of us struggle to live with it. Pain has an essential biological function, but too much — or the wrong sort — ruins lives and puts a sizeable dent in economic productivity. By David Holmes, infographic by Mohamed Ashour.

People with neuropathic pain have struggled to find relief with conventional drugs. Researchers are investigating whether more meaningful pain classifications could help.

In a longitudinal brain imaging study, patients with subacute back pain were followed over the course of 1 year. Initially greater functional connectivity of nucleus accumbens with prefrontal cortex predicted pain persistence, implying that corticostriatal circuitry is causally involved in the transition from acute to chronic pain.

Anterior insula (AI) and medial anterior cingulate cortex (mACC) are activated by self and vicarious pain, disgust and fairness, yet the overlap of these representations are not known. Here the authors provide evidence for shared neural codes in the left AI and mACC and distinct codes in the right AI.

Chronic pain is a common problem that incurs substantial costs to the individual and society as a whole. The efficacy of currently available medications is limited, prompting the exploration of alternative therapeutic approaches. Here, Jensen et al. summarize the state of knowledge regarding the efficacy and mechanisms of four different neuromodulatory interventions—hypnosis, meditation training, noninvasive brain stimulation, and neurofeedback—for the treatment of chronic pain.

The medial prefrontal cortex (mPFC) is implicated in pain regulation, yet the underlying mechanisms are poorly understood. Here the authors establish a critical role for mPFC in regulating pain sensation and pain-related anxiety, mediated by activation of the cyclin-dependent kinase 5 signalling pathway.
