Have the patient place a hand over their forehead and FEEL the related events and/or emotions associated.
The neurons in the Temporal Lobes produce the biochemical GABA and theta brain waves. These lobes assist in balancing the frontal lobes, which govern personality, and the parietal lobes, which control thinking and action. GABA is the brain's natural Valium.
This biochemical controls the brain's rhythm, so you function at a steady pace both physically and mentally.
Remember the gut-brain connection.
