Sensorimotor cortex activation during anticipation of upcoming predictable but not unpredictable actions

Abstract
The mirror neuron system (MNS) becomes active during action execution and action observation, which is presumably reflected by reductions in mu (8–13 Hz) activity in the electroencephalogram over the sensorimotor cortex. The function of the MNS is still fiercely debated. The current study aimed to investigate a role of the MNS in anticipating others’ actions by examining whether the MNS was activated–indexed by mu power suppression–prior to the onset of observed actions when the onset and type of action could be predicted on the basis of environmental cues. Young adults performed and observed cued grasping and placing actions in a card game in a real-life setting, while the predictability of the observed actions was manipulated using rules. Significant mu suppression, relative to within-trial baseline activity, was found both prior to and during executed actions, but also during action observation, and, crucially, prior to observed actions provided they were predictable. No anticipatory mu reductions were found prior to unpredictable observed actions. These results suggest top-down modulation of MNS activity by conceptual knowledge. This is the first study to demonstrate mu suppression prior to action onset–possibly reflecting MNS anticipatory activity–by explicitly manipulating predictability.
