A walk-sum framework of frequency-dependent brain communication architecture
confirms the resolvent describes channels, not dynamics. Propofol anaesthesia collapses alpha channels; in schizophrenia, weakened local dynamics expose the structural scaffold-topological transparency. This framework provides the first analytical derivation of frequency-band communication architecture from connectome topology.
