Story summary

Researchers at the University of Washington studied fruit flies to explore proprioception, the sense of body position and movement.
They discovered that nerve cells detecting limb movement are silenced during walking and grooming, allowing the brain to prioritize posture stabilization over movement.
Interneurons inhibit sensory feedback during motion, enhancing sensitivity to external disturbances.
The study employed calcium imaging to trace nerve pathways and confirm interneuron roles.
Findings could inform treatments for sensorimotor disorders and rehabilitation.
