I take it as a datum of everyday experience that I, me, my consciousness, and the "Witness" that manifests in meditative states, is itself alone and has no relation to brain-body except analogically. The brain is a three-pound skull organ. I am not. It's one thing to speculate that brain machinery somehow gives rise to "I", but quite another to equate brain with "I" - that is a category error of gross proportions. I sometimes wonder 1) how anyone can be so sure about matter, and its so-called reality and solidity, in the face of a new physics that reveals matter's underpinnings to correlate more to nonmateriality than anything else; and 2) how anyone cannot question matter's "reality", when it is, again, a datum of everyday experience that we "know" matter only as an interpretation and even s symbol, within the sphere of our subjective psyche. Matter is primarily a psychic attribute, so one would expect that in this sense psyche is prior to matter. Of course, the psyche also "knows and interprets itself", so the question then becomes, "Who is this knower and interpreter?" I think the answer can only come from internal introspection, not from external means like brain scans.
