My take on this is that much of the heavy lifting here is done in evolutionary older brain stem structures where the basic animal behaviour is shaped by the much smarter cortex. Call them instincts if it helps.
I have some prior posts that may help you get started on sorting this out:
It seems you are approaching motor planning from a human macro planning perspective. A movement is a practiced action that can be emulated. You have watched a fumble and learned to make the fumble move.
Nature has no such bias. In your brain, in the multiple interconnected maps, the token of information is multiple levels of automatic parsing. Each sensory stream gets this treatment. Each planed movement is formed with layers of interacting maps - from the desired action to motor planning and i…
You may wish to start with the vestibular system.
I have a bunch of papers on the contributions of a stabilized platform (the vestibular system) as the starting point of self-reference - but you may wish to start with this one.
What happens if it is broken?
This is closely related to Depersonalization:
Update: I did a little digging and ran across this text. Considering the question you are asking about the system organization of the motor system I think you will be interested in th…
It seems to be a thing for connectome/cortex researchers to ignore the processing that goes on in the “lower” brain structures. These were/are sufficient to run lizards and amphibians. There is absolutely no reason to think that they re not performing much of their original functions inside of the functioning brain.
The lower brain receives a low-resolution image from the eye area “away” from the fovea and directs the eye to point at interesting areas to form identification of an object with a …
I have long thought that the hippocampus/temporal lobe is more of a tourist and less of a driver. [1]
The driver is the midbrain/limbic system.
The back parts of the cortex filter and shape perception, to be registered in hippocampus/temporal lobe as autobiographical memory.
In this general view - the forebrain takes the midbrain “animal impulses” and shape and elaborate them into various actions such as “seeing” (Scanning and parsing visual perception), “hearing” (cocktail effect), and actin…
My working theory on consciousness is fairly simple considering how complex the central nervous system is.
Let me set the table on how I see the brain working:
Focusing on the H of HTM. (Hierarchy)
Consider this in a sensory stream general framework of (raw sense) to (collected sense/association) to (name/symbol) to (collected symbols/grammar) to (working memory) to (the emotionally colored here and now) in the tip of the temporal lobe. This is the stream of sensation that you know as your pe…
As far as HTM and spatial invariance - how does the brain do this?
It’s not all done in one go.
We know something about the processing that is done in the subcortical structures. We know of place cells, grid cells[7], head position cells[6], border cells (more than likely whisker cell signaling in rodents), and goodness knows what else.[13][14] It is clear that the brain is forming an abstract representation of space. We even know the native data structure format - distributed grids.
