Hello my dear friend :)
It's so nice to read this beautifully illustrated and researched work today! Miller's reflection of the left side of the brain being a bit of a bully made me giggle. How nicely put 😄 Not long ago when going through research on language recovery the opposite came up about stroke patients' rehabilitation. That the right hemisphere might "bully" the left, consequently interfering with language recovery Ref. (this remains unclear!).
I am more inclined to follow Beeman and Kounios's line of thought. I think that creative insight is more of a "collaborative work" of different brain areas. As for that aha! moment ... I do have my tiny little ones once in a blue moon. And very much like Breeman and Kounious put it, it happens when I am on a walk or, relaxing in the garden, or even immediately after waking up!
Thank you for the mention my dear @agmoore :) also, I loved what you did with those brain images 😍
Much love from warm Portugal, always & forever :*
