They then implemented a simple spinal circuit whereby the same neurons in the spinal cord that control muscle force (called alpha motoneurons) also scale (i.e., modulate) the stretch reflex ...

By searching for the reflex circuit that contributes to the generation of a steady walking in cats through robotic experiments, the researchers found a simple reflex circuit that could produce leg ...

The simulation experiment: To test whether and how a spinal circuit can allow voluntary movements by modulating or inhibiting movement perturbations that arise from stretch reflexes, the team, led ...

However, the technique achieved the return of some spinal reflexes in patients, proving that the implanted neuron did form a functional neural circuit with the spine after all.

"Spinal circuit dysfunction is rarely considered in movement disorder research, but the symptoms of these conditions are largely produced by neurons resident within the spinal cord.
