Abstract
Motor imagery paradigms can be used to investigate motor preparation. We used positron emission tomography to compare regional cerebral blood flow (rCBF) in patients with Parkinson's disease and normal controls under three conditions: rest, motor imagery and motor execution. In controls, imagery activated bilateral dorsolateral and mesial frontal cortex, inferior parietal cortex and precuneus. Motor execution additionally activated primary motor cortex (p pKeywords
