Abstract

The mirror neuron system (MNS) is considered the best explanation for the neural basis of embodied simulation. To date no study has investigated if it may be activated not only by actual but by the “feeling of movement”. The Rorschach test cards were used to investigate evidence of EEGmuwave suppression at central areas, an index ofMNSactivity, since human movement responses (M) to the Rorschach elicit such feelings of movement. Nineteen healthy volunteers observed different sets of Rorschach stimuli during attribution, identification, and observation of human movements and different scenarios while their EEG were recorded. Significant mu suppression occurred when subjects perceived movement, regardless of the experimental condition. These results show that mirroring can be activated by static, ambiguous stimuli such as Rorschach cards, suggesting that internal representation of the “feeling of movement” may be sufficient to trigger MNS activity even when minimal external cues are present.
