Spatio-temporal analysis reveals active control of both task-relevant and task-irrelevant variables

Kornelius Rácz, Francisco J. Valero-Cuevas
2013 Frontiers in Computational Neuroscience  
Support for this comes from spatial domain analyses (i.e., structure of) of kinematic, kinetic, and EMG variability.  ...  ., in the null space of those goals) variables is evidence of a separation of task variables for efficient neural control, ranked by their respective variabilities (sometimes referred to as hierarchy of  ...  For multifinger grasp, the redundant task space of all applicable forces for static grasp can be mathematically separated into the mutually orthogonal subspaces of force variability that have no effect  ...

Force-stabilizing synergies in motor tasks involving two actors

Stanislaw Solnik, Sasha Reschechtko, Yen-Hsun Wu, Vladimir M. Zatsiorsky, Mark L. Latash
2015 Experimental Brain Research  
We investigated the ability of two persons to produce force-stabilizing synergies in accurate multifinger force production tasks under visual feedback on the total force only.  ...  Our observations show that sensory information on the task-specific performance variable is sufficient for the organization of performance-stabilizing synergies.  ...  In particular, subjects were able to quickly return to the required force target after the quick force pulse produced at t 0 .  ...
