the most interesting insight I’ve ever heard on something close to this topic was in an excellent book by David Hoffsteader called Godel, Escher, and Bach.
There’s a long chapter where he talks about an ant hill, and analogizes it to a brain, with the individual ants acting as neurons. Of course none of the individual ants have any kind of sentience, but en masse the act in a way that absolutely seems guided by a purpose and design in the same way that a mind is.
The mind is the spiritual entity formed by the left (in western and other cultures (it’s the right in some other cultures), but it really doesn’t matter as the mind is functionally identical in all) cerebral-limbic hemisphere of the brain.
The mind is the interface between our being and primarily the world outside our skin and secondarily our body (as an object).
The mind’s function is to think.
Indeed, the billions of living neurons "Borg"ishly integrated in such close proximity create another life at the next level, the spiritual level. The mind, soul and heart are so created.
The soul is the right cerebral-limbic hemisphere of the brain.
The soul is the interface between our being and primarily our body and secondarily the world outside our skin (as a subject).
The soul’s function is to feel.
The heart is the thalamic-hypothalmic region of the brain.
The heart is the center of our being, where our “I am” ontology registers, that is “designed” to run the show and direct-coordinate the activities of the mind and soul.
The heart’s function is to believe (meaning, among other things, to discern truth, not to be confused with a “strong thought” of the mind which is often called a “belief” especially within religious conotations).
The heart, mind and soul are our three foundational aspect entities of our spirituality.
the above doesn’t make that much sense to me, as many many brain structures are bi-lateral.
Most relevant of all, the amygdala, hypothalamus and hippocampus (which regulate emotional responses, anger, etc) are present in both hemispheres of the brain. So it doesn’t really make sense to isolate one particular hemisphere as the “thinking” portion and the other as the “feeling” portion.
Whether or not it makes “sense” to you, it is nevertheless true.
The left side is the world-interface side, and the right side is the body-interface side. That is the essential lateral asymmetry matter of the brain.
The amygdala and hippocampus are bilateral in their cerebral-limbic hemispheres.
They are involved in memory and emotion.
There is a memory and emotion component to thinking as well as feeling.
That’s why, in reality, feeling and emotion are not at all the same thing.
Feeling and emotion just get linked by “thinkers” when describing people who are “emotional” (colloquially meaning that these so-called “emotional” people are feeling dominant as opposed to thinking dominant.)
Because we have both a thinking and a feeling component to memory and emotion we can create very real “pictures” in our imagination that are “three dimensional”, just like the three dimensional picture we get from using binoculars (both eyes) instead of one eye.
The corpus callosum allows the mind and soul direct interface to perform this function.
When the corpus callosum is severed, imagination suffers from that detachment and subsequent envisioning is like squinting through a spyglass with one eye, then (if one is lucky) the other, making it difficult to piece the picture together for the heart’s perusal.
There is, however, no hemispheric bilateralism to the thalamus or hypothalamus. That structure is the center, and is not really cerebral-limbic.
There is only one central entity that is the thalamus-hypothalamus without any left/right composition and it is connected to each of the two hemispheres.
The symetrical trans-lateral structure that contains the hippocampus and the amygdala puts one equal side of that structure deep in one hemisphere and one equal side of that structure deep in the other hemisphere. That structure extends deeply into both hemispheres and is clearly bilateral.
The thalamus-hypothalamus does not extend into the hemispheres – the hemispheres connect to it.
