[Question] Bermudez Interface Problem

I hope this question makes sense although given my confusion it has come out as word vomit and not a pointed question. So sorry for that.

How does commonsense psychological explanation (folk psychology) interface with the explanations of cognition and mental operations given by scientific psychology, cognitive science, cognitive neuroscience and the other levels in the explanatory hierarchy?

Does comparing neurons firing with beliefs/​desires involve a type distinction that renders belief/​desires irreducible to patterns of neuron activity? Is one a belief and the other a belief about a belief? Which is the map and which is the terriotory, or are both the map or both the territory? I am entirely lost.
