Deep Ancestral Animal Spirits, Part One

Here's another older blog post from back in 2012, the first of a three-part series! I'm reposting to my current blog as an archive.
The human brain is a fascinating thing. I had already learned a good deal about it just in personal reading, but when I went through my graduate program to get my counseling psych degree, I got a lot more up-to-date information. For example, I learned about the triune brain—the idea that we have the reptilian brain (the basal ganglia, the most primitive part of the brain), the paleomammalian brain (the limbic system) and the neomammalian brain (the neocortex). What I also learned is that this model is overly simplistic, that it doesn’t correspond as neatly to actual reptile and various mammal brains as is popularly assumed. Also, some non-mammalian species exhibit levels of intelligence and behavior that rival neocortical capacities, without an actual neocortex in the brain. And all mammals have some neocortical development, just not to the degree of humans. So, in short, the triune brain model has fallen out of favor due to its flaws.
Still, as very brief shorthand, the “reptile”, “old mammal” and “new mammal” models of the different sections of the human brain work if you keep its limitations in mind. It’s a good set of mnenomics to remember that the oldest portion of the brain (“reptile”) is that which is associated with primitive territorial and aggressive/defensive actions, the next part (“old mammal”) has diversified into more complex behaviors surrounding the care and feeding of young and other family as well as the first development of emotions, and the newest portion (“new mammal”) has even more complex social and communication skills, as well as planning and foresight.
My interest in it here is as a model for self-reflective meditation. Read the rest at http://thegreenwolf.com/deep-ancest.....rits-part-one/
