Yes.
When the Rinnegan is activated, the Uchiha takes part of Obito’s consciousness into themselves and combine it with their own consciousness, transporting it to another world. When they return from this other world, they gained Akatsuki rings which symbolize their bond with one another as well as give them some degree of power (although there are still limits). The shield and its shape remains relatively unchanged, even when deactivated. Other Rinnegan bearers can be seen with these Akatsuki rings without activating the Rinnegan or being bonded to anyone else on a mental or spiritual level (except Madara). These people show an increase in brain activity between 13% – 19%.
