Description
Pain research currently faces translational crisis, with few preclinical studies translating to new pain medicines. In this talk, Dr. Ma will discuss a new anatomical and functional subdivision of the somatosensory system: one for detecting external threats and driving reflective-defensive reactions to prevent or limit injury, and the other for monitoring internal body injury that produces affective tonic pain and drives self-caring response to reduce suffering. With this circuit-level segregation, he argues that reflexive-defensive assays may not necessarily be able to detect selective loss of clinically more relevant pain, and their wide use by the pain field could contribute to poor translational success.
