HTM & columns Working and biological consistence

@Predictor

What i understood about the working of this structure is that a single neuron in a given minicolumn get inputs and outputs of every neurons in all minicolumns of the given cortical column

Welcome to the community!

There are clusters of cells in the mini-column but each has its own dendrites that radiate from the cell body. As each dendrite snakes through the surrounding area it passes a small subset of the 220 or so mini-columns in the neighborhood of that mini-column.

The collection of mini-columns also contains the rising axons that are projected to this area and are part of what is sampled.

I have posted on the biological details here:

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 hope this gives you some insight it what HTM is modeling.
