Analysis of brain mechanism of whole body motor learning with special regards to mirror system

In this study, how brain worked is analyzed when actions that could not been done was imagined. When subjects imagined the action of back flip transcranial stimulation was applied to the primary motor cortex. Motor evoked potential was enlarged as compared during resting in subjects who could do the action, but no such enlargement was observed in those who could not do. This means that the action that cannot be done, cannot be imagined either. Furthermore, in the subjects who could do the back flip after 1 month training, motor evoked potential became larger, meaning imaging of the action became possible.
