**Abstract. **
While the equations of canonical physics represent *statements* about the *states* of a physical system, the fundamental theory of the brain is based on a formalization in which the *statements* of the system are simultaneously the *states* of the system. The resulting dynamical equations for brain states emerge as duals of the canonical quantum-mechanical equations where one replaces complex wave functions by real state vectors and a differentiation versus time by a differentiation versus truth-value. Self-referential cognitive operations satisfy the supersymmetric Schrödinger equation of motion with corresponding infophysical effects resembling the structure of the frustration effect in spin glasses.
