Limbic Root System – Our Limbic Brain Brain implants what has been indoctrinated or what has had a significant emotional impact on our 0-7 age brain. This imprintation makes for a deep-seated emotional root system. Once this Mammalian stamping-in takes place it is extremely difficult to erase or change. I suggest the limbic root system can be compared to a tree: 1.) the branches of the tree are the ways we interact, for good or bad, with the world. Our emotions, thoughts, and behaviors are expressed on the branches, 2.) the trunk of the tree is the person, the self, a living being, and 3.) the roots represent imprintation of early indoctrination that can be positive, negative, or neutral. There can be the deep-seated roots where abuse and hurt are repressed in the personal unconsciousness. Our inborn unmet needs are often buried in the personal and the collective unconscious.
