Yes but resolution and coherence matters. A map that says "here be dragons" is not high resolution. A map that misidentifies or misses parts is incoherent. The brain is not physical (as explained above), and cannot be captured in a sufficiently high resolution map that only studies substance and its interactions. Since we have no access to the formwork, we will always have missing data, that hampers our ability to create such a coherent map.
Thank you for staying engaged, it's helping me see my position more clearly.
