We have a set of core regulatory networks (CRNs), or neural systems, originating in the lower parts of the brain and spreading throughout the whole brain, that work together to keep us regulated in the face of various stressors. Collectively, the branches of this Tree of Regulation direct or influence all functions of the brain (like thinking and feeling) and the body (impacting your heart, stomach, lungs, pancreas, and more). They are trying to keep everything in equilibrium, everything regulated, everything in balance.
