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

在这项研究中，当想象无法完成的动作时，大脑是如何工作的。当受试者想象后空翻动作时，对初级运动皮层施加经颅刺激。与休息时相比，能做动作的受试者的运动诱发电位增大，但不能做动作的受试者没有观察到这种增大。这意味着不能做的事，也不能想象。此外，在训练1个月后能够做后空翻的受试者中，运动诱发电位变大，这意味着该动作的成像成为可能。

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.
