Temporal summation of pain sensation is pivotal both in physiological and pathological nociception. In humans, it develops in parallel with temporal summation of the nociceptive withdrawal reflex (NWR) of the lower limb, an objective representation of the temporal processing of nociceptive signals into the spinal cord. ⋯ The study demonstrated that TST of the NWR involves a selective deactivation of PCC.

Chronic pain is a growing societal concern that warrants scientific investigation, especially given the ineffectiveness of many treatments. Given evidence that pain experience relies on multisensory integration, there is interest in using body ownership illusions for reducing acute pain. ⋯ Pain intensity in chronic pain patients was reduced by 37% by 'out of body' illusions. These data demonstrate the potential of such illusions for the management of chronic pain.
