Subcortical lesions have been simultaneously implicated in both real and simulated movement deficits, suggesting that as with frontal le- sions, self action representation and programmation are the same process. We have analyzed the simulated precision grasping in subjects with idiopathic bilateral PD compared to a healthy control group. Re- sults showed that individuals with PD are impaired in the mental rep- resentation of a grasp orientation but are still capable of normally ex- ecuting this movement. These observations reveal that programmation and execution of movements is spared and that motor representation is selectively impaired. Thus, programmation of real acts and representa- tion of motor action are distinct processes.
