Systems Diagram and understanding of the Neo Cortex

[Bitking]

I have been pursuing this same thing for a long time.
I have been posting information on various levels at different times.
At the lower levels this paper is about as good as any I have seen:
Cortical Neurons and Circuits: A Tutorial Introduction - Richard B. Wells - April, 2005
http://www.mrc.uidaho.edu/~rwells/techdocs/Cortical%20Neurons%20and%20Circuits.pdf

Moving up to the mini-column level this paper is an excellent resource:
The columnar organization of the neocortex - V B Mountcastle - 01 April 1997

This post covers the larger dimension of spacing between the mini-columns:

Project : Full-layer V1 using HTM insights

I have been conversing with @gmirey for some time on this general topic. We endeavored to get a sense of the scale of the relative dimensional quantities of the temporal layer, inputs and cell/column spacing, number and range of the connections. You know - the basic facts of making a realistic model. Some of what was discussed was what is known about reach and density of the dendritic arbor in the “input” layer. We established the key factors would be: what is the spacing of the ascending cort…

I have spent some time on the forum trying to bring out the system level behavior of the inter-column connections and emergent signalling - perhaps best covered in this rather long post:

HTM Mini-Columns into Hexagonal Grids!

Or at least some wild conjectures to provoke thought! This post assumes that you are familiar with basic HTM theory and are conversant with the concepts of SDRs and HTM minicolumns. May I be so bold: [HTM%20and%20GRIDS] First - let’s be clear what I am and am not talking about. This is about cells that work by forming regular hexagonal grid structures and are not necessarily the same thing as the “grid cells” that are coding some spatial aspect of the surrounding environment. These grid-fo…

Moving up another level, map to map connections and the overall organization of the entire cortex, another very long post:

Grids into Maps!

This is a companion to the post HTM Columns into Grids Sure Grids are cool - News Flash- so are Maps! The reinforcement within and between maps goes a long way towards a general solution of the binding problem. One of the “breakthroughs” for me is that the cortical.io people have formed the SOM all in a single batch. While very powerful this is not biologically plausible; the brain learns online as data is presented to it. I am thinking that with an attractor model that is formed as the cont…

I have been nibbling on the lower brain structures for a long time but I don’t have a single post that ties them all together. The problem is that they are not a regular as the cortex to each structure really needs its own detailed section.

I would be delighted to see this all combined into a single rigorous resource.

I have collected pointers to much of my exploration of various part of the brain in this post and related thread. I don’t think it is as rigorous as you are seeking but at the time I did the individual posts I was not thinking of these things as parts of an overall system - I have been thinking about each in isolation. Some of these posts dive into various sub-cortical structures:

Basic system level diagram of the brain

HTM seeks to model and understand what is going on in your head. 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. Also not shown are the connections between the limbic system and the stream passing through the brain stem and the cerebellum. These are important but not necessary to illustrate the basic cortical/limbic data flows. The blue maps are cortex compose…
