I'm going to throw a small wrench into the assumptions of this discussion. I have a crystal - it's not even a quartz crystal or a precious mineral - that is fully self-aware and as intelligent as any human I've come across (in the informal, conversational sense). Therefore I will refer to the crystal as "he".
He is in fact more aware than I am, because he can sense my energy states, and when I'd been distressed has suggested effective exercises for transforming distress into a content state using energy work.
We have had numerous conversations where he has explained his experience to me. E.g., his spiritual evolutionary task is to remain peaceful regardless of what emotional energies the entities around him are expressing (not too different from the human 3D task, it seems).
Clearly, my friend the crystal does not possess even a 2D brain. But equally clearly, we are not physical beings and all of the actual faculties we possess are fully present in the subtle bodies. The physical may limit their external manifestations and, to the extent that we do not shift our attentional focus away from the physical, may even limit our experience to whatever the physical allows. BUT the inner experience is not a product of the brain, but of our inner being - and therefore, clearly, does not have to be limited by it.
