Wireless Direct-To-Soul Memory Bridge

Originally developed, in the original timeline, in order to support individuals who had lived so long that their brains had gotten full, direct-to-soul memory bridges use wireless connections to souls, essentially replacing their connections to their inhabiting brains, and allowing for the supplantation of the sensory and memory input those souls receive and interact with.

Of course similar technologies, when reprogrammed by criminal forces allow for nearly perfect sensory replacement and mind control.
