title: Quantum mathematical cognition requires quantum brain biology: the "Orch OR" theory.
abstract: The "Orch OR" theory suggests that quantum computations in brain neuronal dendritic-somatic microtubules regulate axonal firings to control conscious behavior. Within microtubule subunit proteins, collective dipoles in arrays of contiguous amino acid electron clouds enable "quantum channels" suitable for topological dipole "qubits" able to physically represent cognitive values, for example, those portrayed by Pothos & Busemeyer (P&B) as projections in abstract Hilbert space.
