Sažetak
Mirror neurons are multimodal association neurons with motor properties in premotor and posterior parietal cortex that increase their activity and fire not only during action execution, but also while observing or hearing another individual performing the same or a similar action. Mirror neurons play important role in action recognition, imitation, empathy, and also in the theory of mind. Electrophysiological index of mirror neuron system activity is an EEG oscillation called mu rhythm. We created an EEG experiment with focus on mu rhythm as the indicator of mirror neuron system activity. The core research question was to find the highest mu power in relax condition and similar mu suppressions in self motor movement, and the same observed movement condition. Within the second research question we expected to find contralateral correlations in mu rhythm strength according to index finger side in nonrest conditions and hemispheric differences in mu power also in nonrest conditions. The results showed statistically significant suppression from baseline in mu oscillations over both hemispheres during nonrest conditions, supporting our expectations of the first research question. Results for our second question were statistically insignificant, what contradicts our expectation. However, from this finding we can assume that the mirror neuron system activity is not hemispherically differentiated for distinguishing left and right side movement, but rather approximate to distinguish and understand any kind of movement.
