Proprioceptive sensory-driven mechanisms shape Clarke's column development.

Coordinated locomotion depends not only on motor programs but also on the sensory feedback that refines them. Proprioceptive sensory neurons (pSNs) modulate motor circuits through direct synapses, yet their role in shaping spinal cord circuits has remained unclear. Here, we uncover an essential function for pSNs in org...
