Adaptation to visuomotor rotation with increasing angle.

The panels show successive movement endpoints obtained from simulation during adaptation to rotation by 60, 75 and 85 degrees. The color of each point represents the trial number. The ‘+’ shows the target position. Only the adaptation phases of individual simulations are plotted. To emphasize the effect, the degradation rate in the cerebellum was set to zero. As the rotation angle increases, the trajectory first starts spiraling while converging to the target (the middle panel) and then exhibits oscillations around the target with non-decaying amplitude (right panel).
