Hypokinesia and bradykinesia in Parkinson’s disease are consistent with reduced motor vigour, not an impaired capacity to generate and transmit neural drive to muscle

Abstract Hypokinesia and bradykinesia in Parkinson’s disease have been attributed to reduced motor vigour, an account that assumes the neural drive to muscle is intact but inappropriately scaled; an alternative is that generation of the drive is itself impaired. We recorded high-...

Probabilistic inference of homonymous and heteronymous recurrent inhibition in human muscles from large-scale motor neuron recordings

Understanding how spinal circuits shape motor neuron behavior during muscle contractions remains a major challenge. Here, we combined large-scale motor unit recordings with simulation-based inference to generate probabilistic estimates of homonymous and heteronymous recurrent inh...
