Left Right and Different

The Divided Brain

We used to believe the two parts of the brain work in harmony, but according to London psychiatrist Iain McGilchrist, there’s a definite shift in our modern culture which favors left-brain dominance—and it’s something we ought to watch out for and correct. In The Master and His Emissary: The Divided Brain and the Making of the Western World (Yale University Press, 2009), McGilchrist discusses the hemispheres and their different “personalities,” and then shows a sweeping dissertation on the history of Western civilization as seen from the context of the divided brain. - 

Tales from Both Sides of the Brain

GAZZANIGA: ... And together, that's where the whole popularized notion of "left brain, right brain" came out of. And it was a little over-sold. And as we moved on through the study of these patients and others for fifty years, we learned, it's not quite that simple.
FLATO: Yeah, because we, everyone, walks around saying, I'm a left hand, a right-brained person. That's too right.
GAZZANIGA: It's fun, cheap. What's the new word now? Edutainment. It's a little something and a lot of fun.
FLATO: Michael, that word's thirty-years-old.

I have not read either of the books linked above but enjoyed listening and reading the linked interviews.  I especially found Dr. Gazzaniga reports on cases of the right hemisphere being able to talk after many years of silence interesting. The awareness of my left sublingual musculature as a different structure from my right sublingual musculature did not exist for me until I went looking for it. In the same manner I was unaware that I did not see the persona in the left side of someone else's face. It took a great deal of time and effort and play to discern the difference of how I see another's face and the way there is a total adaptation of my musculoskeletal orientation based on what I see. I believe I can now talk using both hemispheres of my brain based on the new musculature and perceptual differentiation.
