An introductory exposition of Quantum Brain Dynamics (QBD) is presented in which the fundamental physical process of the brain can be described within the realm of quantum field theory. QBD is nothing else but Quantum Electrodynamics (QED) of the electric dipole field of dipolar solitons and water molecules with a symmetry property under the dipole rotation. The highly systematized functioning of the brain is found to be realized by the spontaneous symmetry breaking phenomena. Memory printing, recall and decay processes are represented by the fundamental physical processes standing for the phase transition process, the symmetry restoring process and the quantum tunneling process, respectively.
