HTM seeks to model and understand what is going on in your head. We can quibble about details but it is clear that as data course from area to area it stays in a mostly parallel form. The maps of the various sensory fields, while “crazy quilted” are preserved in the hierarchical processing.
The model shown by @ddobric show a concentration that is not found in any of the papers that I have read regarding cortical processing.
So where does this all come together?
I tossed this drawing together from memory so it is sure to be missing some connections. I skipped the thalamic connections all together as this was already a very complicated drawing.
The blue connections in the various sensory streams are essentially in parallel form.
The broad green hub connections connecting the various highest levels in each lobe are also parallel.
I coded the data transformation connections in orange
The EC/HC complex has some scaling where representations in multiple scales exist, but each maintains topography. The rest of the limbic system does not look anything like the cortex. The processing models look more like the classic Boltzmann network
s. Or perhaps a Hopfield Network
What is presented to the lower brain “wraps around” the complexes, transforming the topographic representation into a “spherical input” form. The limbic clusters don’t work the like the cortex so it should not be surprising that the topological format is transformed as the data is conveyed. The connections between the inputs to the limbic system and outputs to the prefrontal cortex all do some data rearrangement to make the data formats compatible.
