I would say that the stuff making up “the map” is not stuff inside the brain. Instead, it is stuff inside the mind, and the mind is “emergent from” the brain (or, if you prefer, the mind “reduces to” the brain).
The neurons in the brain reduce (through several levels) to brain quarks. The map ideas in the mind also reduce to brain quarks, but they do so in an odd way. I choose to label that kind of oddness “emergence”, but the local powers-that-be seem to disapprove of this terminology.
