In his article, “Searching for the Mind,” (jonlieffmd.com/blog/neuronal-networks-brain-waves) Dr. Lieff discusses neuronal networks and brain waves. I am posting a paragraph from his article that is descriptive of the synchronicity of brain waves in neural synaptic networks and its significance.
The changing dynamics of wide-ranging neuronal circuits occurs throughout the brain in milliseconds at the level of individual neurons and groups of neurons. Neurons join a circuit one moment and another the next moment. Groups of neurons fire action potentials in very specific rhythms that rapidly change. Groups of neurons produce brain waves - synchronous oscillations - that communicate information from one section of the brain to another. Synchronous brain waves couple with other frequencies to connect multiple regions.
