I'm surprised by how much this publication reads like an advocacy piece for a specific viewpoint, rather than an objective review of existing literature.
Just from reading the paper, it is clear that there are many experts in the field that take the opposing viewpoint that is being attacked in the paper, especially considering that their hypotheses have been published in widely circulated textbooks.
When it comes to research publications in general, I very much prefer to hear an objective, good faith presentation of the major viewpoints, with the author taking an opinionated but measured take in the conclusion as they review the overall weight of the literature. I'm sure there are issues with this "triune brain" model, but at a certain level every model is inaccurate; the real question is whether a model is useful in its framework, and the answer has a degree of subjectivity such that I do not think it is fair to categorically reject the perspectives of opposing experts in the field.
