| summary | I will describe a series of experiments in which we investigated how the actions of patients with Parkinson's disease can be influenced by visual stimuli and by stimuli that evoke specific actions. It is well known that visual stimuli, such as lines on a path, can sometimes facilitate motor responses in Parkinson's patients; but it is unknown whether stimuli evoking specific motor responses, such as grasping a cup, also affect behaviour. In healthy individuals the motor system can be activated merely by observing a person or object even when there is no intention to act overtly. In this work, we investigated whether these two different types of action-relevant visual stimuli, which implicitly activate sensorimotor brain areas in healthy individuals, also automatically activate actions in Parkinson's patients. |
