of the brain. Their behavior is described by Bizzi et al. as: *In a baseline epoch (no force field on the end effector), they have one preferred direction *In a force perturbation epoch, they show a change in the preferred direction *In a subsequent washout epoch (no force field on the end effector), the change in preferred direction persists.
