The aim of this study was to answer the following question: are there differences between the attenuation of μ rhythms, recorded with EEG in the parietal area during observation of movement and the creation of its imaginative representation? In addition, we checked the extent to which the μ rhythm suppression depends on whether the observed and the imagined movement is performed by a human or is artificial. As a result of the experiment a significant difference in μ rhythm suppression between the conditions "Observation," "Imagery," and "White noise" was recorded. It did not matter whether the motion was carried out by a human being or performed by a machine. The results are discussed in the light of findings which relate to the mirror neuron system.
