Man can image body movement (motor imagery) without actual execution of movement. This indicates we handle our body schema with a certain body image. We demonstrated that the body schema could be modulated by motor illusion, which was applied by mechanical tendon vibration. We also showed this motor illusion activated motor related cortical areas, such as M1, that might be responsible for generation of the motor sensation.This motor illusion could be modulated by motor imagery that was performed during tendon vibration. If the motor imagery was agonistic to the direction of motor illusion, the illusion was enhanced, while antagonistic imagery reduced illusory angles. This motor-illusion-imagery interferences activated many cortical areas, such as cingulated motor area, supplementary motor area, dorsal premotor area.

人可以想象身体运动（运动想象），而无需实际执行运动。这表明我们用特定的身体意象来处理我们的身体图式。我们证明了身体模式可以通过运动错觉来调节，运动错觉是通过机械肌腱振动来应用的。我们还展示了这种运动错觉激活了与运动相关的皮质区域，例如 M1，它可能负责产生运动感觉。这种运动错觉可以通过肌腱振动期间执行的运动想象来调节。如果运动想象与运动错觉的方向相反，则错觉会增强，而对抗性想象会减少错觉角度。这种运动-幻觉-意象干扰激活了许多皮质区域，例如扣带运动区、辅助运动区、背侧前运动区。
