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 ...

New research suggests pain is not a simple signal of injury but a process that unfolds across nerves, spinal cord, and brain.

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 ...

Researchers have discovered that a particular molecular signaling pathway plays an important role in producing osteoarthritis (OA) pain. Using a mouse model of painful osteoarthritis, they show that ...

A neural circuit hidden in an understudied region of the brain plays a critical role in turning temporary pain into pain that can last months or years, according to new University of Colorado Boulder ...

Researchers have uncovered a neural pathway preferentially involved in pain perception across species. The study was led by Profs. Tu Yiheng and Hu Li from the Institute of Psychology of the Chinese ...
