I personally like the McGilchrist-Jaynes exchange on this topic and I find McGilchrist's idea actually fascinating.

> McGilchrist likely felt compelled to go out of his way to criticize Jaynes’s theory because McGilchrist is arguing for the exact opposite case as Jaynes: that rather than our brain hemispheres being more integrated today than in the distant past, he argues that they are now less integrated, and that our brains have essentially been hijacked by our left hemispheres. Further, according to McGilchrist, this left hemispheric dominance is the cause of most of the ills of Western civilization. For all of these sweeping claims, he presents shockingly little evidence.

Marshall McLuhan was influenced by hemispheric science and Jaynes in his observations about cognition and media.

McLuhan never claimed any theories, he "probed" and free associated to develop the idea that the phonetic alphabet and visual (spatial) continuity led to our cultural bias towards discrete, highly linear thought. He speculated that the work of Euclid could not have appeared without the phonetic alphabet.

McLuhan also proposed a brain hemispheric bias of mental adaptation between the Occident and the Orient: that as electronic media (particularly TV and telephone) was inducing a shift of western adaptation towards the East, the phonetic alphabet and mechanical media (printing press / copy machine) were doing the reverse in the East.
