Equilibrium Point Control Cannot be Refuted by Experimental Reconstruction of Equilibrium Point Trajectories [PDF]

open access: yesJournal of Neurophysiology, 2007
In the literature, it has been hotly debated whether the brain uses internal models or equilibrium point (EP) control to generate arm movements. EP control involves specification of EP trajectories, time series of arm configurations in which internal forces and external forces are in equilibrium; if the arm is not in a specified EP, it is driven ...
