“Action-Stabilizing Synergies During Finger Force Production Tasks: Spinal and Supraspinal Circuitry Involvement and Effects of Visual Feedback Removal”

https://pubmed.ncbi.nlm.nih.gov/38116603

The abstract reports on a study that found two types of action-stabilizing synergies during finger force production tasks, reflecting spinal circuitry for motor unit synergies and supraspinal circuitry for multi-finger synergies, with the latter being more susceptible to disruption by removal of visual feedback.
