Supercomputer models to reveal how nerve cells control movement
Supercomputer-based Models of Motoneurons for Estimating Their Synaptic Inputs in Humans
This project uses advanced computer models together with recordings of muscle nerve signals to work out how spinal and brainstem neurons send the excitation, inhibition, and neuromodulatory signals that drive human movement.

What this research studies
If you take part, researchers will record signals from many of your muscle's motor units while you perform movements. They will run detailed motoneuron models on supercomputers to simulate how excitatory, inhibitory, and neuromodulatory inputs combine to produce those recordings. By reverse-engineering the recorded firing patterns, they aim to estimate the hidden neural inputs that drive movement. This approach builds on newer multi-unit recording methods and realistic neuron models to connect muscle activity to the underlying nerve signals.
Who could benefit from this research
Good fit: Ideal candidates would be adults willing to undergo motor unit recordings, including people with movement disorders (for example, ALS, spinal cord injury, or post-stroke weakness) and healthy volunteers for comparison.
Not a fit: People with conditions unrelated to motor control or those who cannot undergo muscle recordings would be unlikely to benefit directly.
Why it matters
Potential benefit: If successful, this could improve diagnosis and help design better therapies or monitoring tools for people with movement disorders.
How similar studies have performed: Motor unit recording and neuron modeling methods have been used before, but applying supercomputer-driven reverse-engineering to separate excitation, inhibition, and neuromodulation in humans is a novel step.
