Query: The Model of the Theory of the Quantum Brain Dynamics can be cast on the
  Heisenberg Spin Hamiltonian   In this note, we show that the model of the quantum brain dynamics can be
cast on a kind of the Heisenberg spin Hamiltonian. Therefore, we would like to
emphasize that the quantum dynamics of brain should be understood by the
physics of quantum spin systems.
