The Utility (A) and Risk (B) function for the Motor Module as a function of distance to the doorway. As seen in (A) the controls show the highest Utility along with a gradual change in the gradient, while PD freezers show almost no change in the Utility far away followed by a sharp decrease near the doorway. The Risk function (B) also peaks closer to the door in case of both the PD freezers and non-freezers.
