Differential activation of brain regions involved with error-feedback and imitation based motor simulation when observing self and an expert's actions in pilots and non-pilots on a complex glider landing task

► Degenerate neural processes in cerebellum and cortex exist for observation of action. ► Processing of observed action is dependent on experience. ► Observation of an expert's action utilizes imitation based motor simulation in cortex. ► Observation of previous action utilizes error-feedback motor simulation in cerebellum. ► Observing action activates regions inside and outside the action execution network.
