Thoughts about topology

Please check out this classic description of the visual topologic map organization:

And this one showing preservation of topology in the subsequent map-to-map connections.

Much of this is highly topologically arranged.

Following up on a basic HTM tenant - the brain uses much the same arrangement everywhere. I have no reason to believe that this basic principle fails as we move from the sensory areas to the association areas. I have been looking to the connectome project to see if the association areas are surrounded with specialty processing areas like V1 and the auditory cortex. (Examples: motion, texture, color, phase delay, …)

I will have to dig through my papers to find the ones that show the topology being preserved going from map-to-map in other sensory streams but for now here are some related links showing how important preservation of topology is in the sensory encoding areas:
