His theory was that the two brain halves communicated through inner voices. Wernickes Area, on the left side, communicated with the similar area on the right side. WA is where we comprehend speech, so Jaynes theorized that was why bicameral people experienced the communication as inner voices.

The research in the new research paper is about a split between front and back of the brain. So something entirely different. That split is an old idea. Jaynes would most likely have known about it. But it wasnt part of his theory.
