	abstract = {<p>Locomotion requires coordinated motor activity throughout an animal{\textquoteright}s body. In both vertebrates and invertebrates, chains of coupled central pattern generators (CPGs) are commonly evoked to explain local rhythmic behaviors. In C.\&nbsp;elegans, we report that proprioception within the motor circuit is responsible for propagating and coordinating rhythmic undulatory waves from head to tail during forward movement. Proprioceptive coupling between adjacent body regions transduces rhythmic movement initiated near the head into bending waves driven along the body by a chain of reflexes. Using optogenetics and calcium imaging to manipulate and monitor motor circuit activity of moving C.\&nbsp;elegans held in microfluidic devices, we found that the B-type cholinergic motor neurons transduce the proprioceptive signal. In C.\&nbsp;elegans, a sensorimotor feedback loop operating within a specific type of motor neuron both drives and organizes body movement.</p>
