Coordinated movement relies on the nervous system constructing a real-time representation of the body in space and time, grounded in proprioceptive signals of force, position, and motion. The cervical spinal cord is the first central site where forelimb proprioceptive inputs are integrated and transformed into structured neural representations. This proposal aims to define how specific spinal neuronal cell types encode and assemble these signals to generate a functional representation of forelimb state.
