The purpose of this study was to investigate the possibility of applying action observation as an alternative approach to motor imagery by analyzing the electroencephalogram patterns of cerebral cortex during motor imagery and action observation of elbow flexion and extension. Twelve male university students imagined and observed elbow flexion and extension of left, right, and both arms in the motor imagery and action observation condition respectively. EEG data were measured during motor imagery and action observation from the specific scalp areas including C3, C4, P3, P4, O1, and O2. Analysis of the relative alpha power revealed significant differences among certain types of imagined action in the sensorimotor(C3, C4, P3, P4) and occipital cortex(O1, O2) during motor imagery, displaying increasing tendency during action imagination compared to the resting state. During action observation, however, the relative alpha power showed significant differences among the types of observed action in the sensorimotor and occipital cortex, displaying significant decreases during action observation compared to the resting state. Analysis of relative beta power revealed no differences among the types of imagined action in the sensorimotor and occipital cortex during motor imagery. During action observation, however, the relative beta power showed significant differences among the types of observed action in the sensorimotor and occipital cortex, displaying significant increases during action observation compared to the resting state. Taken together, these results suggest that action observation may generate stronger cognitive activity than motor imagery. Therefore, action observation can be applied to the motor learning and/or rehabilitation situations as an alternative approach to motor imagery.
