  • “Reaching decisions during ongoing movements”Journal of Neurophysiology 2020
  • Please feel free to share your thoughts or feedback through the jclub mailing list: 

    We often make decisions while moving (i.e. “decide-while-acting”). Drummers, for instance, decide when and where to move their arms during movement. In lab settings, however, researchers often use standard delay tasks (i.e. “decide-then-act”), and most action selection models are based on this “decide-then-act” paradigm. 

    Michalski and colleagues asked human subjects to track moving targets, and the authors demonstrate interesting differences from the classical “decide-then-act” model. Biomechanical cost, which is computed by muscle torque to make switching movements to a different target, does not correspond to subjects’ probability of switching. They use this data to hypothesize neural circuits for controlling ongoing movements and those for action selection are different, and that biomechanical costs may be computed in the cerebellum.
