Abstract

The role of the mirror system in action understanding has been widely debated. Some authors have suggested that the mirror system plays an important role in action understanding (Rizzolatti and Sinigaglia, 2010), whereas others have claimed that direct evidence to support this view is lacking (Hickok, 2009). If mirror neurons have an active role in action understanding rather than passive visuomotor transformation during action observation, they should respond differently to the observation of actions depending on the intentions of the observer. In this fMRI study, twenty participants observed identical actions under different instruction contexts. The task was either to understand the actions, identify the physical features of the actions, or passively observe the actions. A multi-voxel pattern analysis revealed unique patterns of activation in ventral premotor cortex and inferior parietal lobule across the different contexts. The results suggest that ventral premotor and inferior parietal areas respond differently to observed actions depending on the mindset of the observer. This is consistent with the view that these regions do not merely process observed actions passively, but play an active role in action understanding.
