‘Motion’, as expressed through high-level features of music, combined with mirror neuron (MN) system activation is studied in this article. The mechanism of MN involved in the perception of musical structures is seen as a means for cueing the learner on ‘known’ factors that can be used for his/her knowledge scaffolding. To explore such relationships, EEG recordings, and especially the Mu-rhythm over the sensorimotor cortex that relates to the activation of MN, were acquired and explored. An experiment was designed to provide the auditory and visual stimuli to two groups of subjects, advanced music students and non-musicians as a control subject group. The musician group’s response to ‘motion’, implemented by Modest Mussorgsky’s ‘Promenade’ and a corresponding video clip, was monitored. The acquired signals, after appropriate averaging in the time domain, were analyzed in the bifrequency domain, using bispectral analysis. Experimental results showed that motion inherent in high-level features of music, could be associated with Mu-rhythm modulation. Such modulation provoked by the MNs could cause bispectral fluctuations, especially when visual stimulation is combined with an auditory one. These results pave the way for further exploitation of the role of MNs in music and, in general, knowledge perception.
