We still do not know the specific mechanisms of brain or neural computation. But the great studies of the past on brain physiology has enabled us to form a simple and intuitive model of how the brain generally works.
Neurons synapse synchronously as a group in computing elements of information.
Neural waves of energy sweeps harmoniously across layers of brain cells or neurons repeatedly many times a second so that the brain can make decisions on sensory stimulation from outside the body and on biochemical signals inside the body. The neural waves signals neurons to fire or synapse in sequence in a chain reaction. Coherent information arises from the different sequences of neurons which synapse. Essentially, the power of the brain lies in its capacity to control which sequences of neurons synapse. It's important to think about how the brain works overall because your general model will affect the details of the neural computing processes.
