Nice article. Stimulation of the Vagus nerve does indeed improve memory, I have some papers lying around on that issue.
I predict that before brain-computer interfaces become the big seller in bionics, autonomous nervous system controls will be the big thing. Useful, can do stuff a wearable cannot, doesn't rely on highly complex connections (merely complex ones).
