Four tiny 3D organs connected themselves in a lab dish, forming a replica of the human pain pathway, in a new study. The discovery allows scientists to better understand chronic pain and how pain ...

Scientists have re-created a pain pathway in the brain by growing four key clusters of human nerve cells in a dish. This laboratory model could be used to help explain certain pain syndromes, and ...

Stanford Medicine investigators have replicated, in a lab dish, one of the most prominent human nervous pathways for sensing pain. This nerve circuit transmits sensations from the body’s skin to the ...

Scientists have discovered a brain circuit that gives pain its emotional sting, explaining why some hurts linger as suffering. The breakthrough challenges our beliefs about how we process pain and may ...
