Elon talked about this 10 years ago, saying we currently have 2 layers and how Neuralink could be the third:
“When Elon refers to a “digital tertiary layer,” he’s considering our existing brain having two layers—our animal limbic system (which could be called our primary layer) and our advanced cortex (which could be called our secondary layer). The wizard hat interface, then, would be our tertiary layer—a new physical brain part to complement the other two.”

The idea of the brain having a primitive layer and more refined layers is much more than ten years old [0]. The new finding here is that distinct layers have different progenitor cells.
Interesting, thanks for the insight! According to your Wikipedia link, the Truine brain theory is not widely recognized.. maybe this will change that to some extent.
I'm no expert, but my understanding is that modern neuroscience has moved away from the idea that specific areas of the brain control specific behaviours.
when I was in school we were taught that the human brain was really two brains - the left and right hemispheres. it seemed to explain how you could learn a skateboard trick in your normal stance, then have to learn it again switch.
these are not separate organs these are separate "stem cell" populations.
under such a statement as submitted all of our organs that derive from varied populations of expressive constituency, would be amalgams of more than one organ.

The article discusses front and back rather than left and right sides of the brain
no it isnt. it is derived from disparate progenitor cells.

very naive question: does organ even have a strict enough definition for discussions like this to be worthwhile?
