So, having skimmed some studies on split-brain patients, it makes me wonder about the whole "left-brain/right-brain" dichotomy that made its rounds in public perception some time ago.
I'm not sure how much of that is really good science, but it looks like there's some real truth to the different sides taking on different roles and cognitive abilities.
One thing in particular I wonder about now, is can you map Carl Jung's concept of Anima (I'll refer to the Anima, but what I have to say applies to Animus, as well) onto the right half of the brain?
Jung's idea of Anima was essentially the male brain's mental image of "the typical woman". Thus it would posses typically feminine traits.
Since the right half of the brain is associated with creativity, emotional response to (ie, recognizing) faces, and is more typically "feminine", would it be possible to devise an experiment with MRI to see if invoking the anima fires more neural activity on the right half of the brain?
Say, have a subject describe "the typical woman" and watch activity, have them describe "the typical man" and some other controls to also invoke creativity and see how the neural activity compares? See if when men don a dress, their right-brain fires more activity than if they just don any other unfamiliar clothing (a hospital gown or a robe are gender-neutral but may also be unfamiliar enough to control for that part alone)?
It's a very roundabout way of asking, but hopefully the questions kind of highlight the underlying question;
in terms of Jungian Psychology, is it reasonable to hypothesize that you could split the hemispheres of the brain into "persona" and "Anima" as "left" and "right"? (and perhaps reversed for Persona and Animus)
The interesting thing is that this leads to a testable hypothesis perhaps some people here already know the answer to: Is there any link between gender dysphoria and right-brain dominance? If there is, that would seem to support that hypothesis that the left hemisphere generally takes the masculine identity and the right houses the Anima (in general, though I would expect if the Anima exists as a largely separate neural network (or combined set of networks) that it would probably at least share a little activity on the left hemisphere).
