The link below is a good review article on the minicolumn hypothesis. I don't speak for the whole group, but my understanding is that NuPIC is based on minicolumns as the the fundamental computational unit.
Macrocolumns are essentially structures consisting of many minicolumns. You're right though, there is no consensus on this question (the significance cortical columns). There is a reasonable amount of supporting evidence, but since we don't fully understand how these columns operate so it remains a hypothesis. As the link you referenced points out, it is possible that the repetitive structure and organization of these columns could be the result of patterns of development rather than function. My feeling is that no doubt development plays a significant role in the organizational structure, that does not preclude it from establishing a significant functional role as well (i.e. given the small-world network organization of the brain, the developmental origins may well have given rise to the functional capabilities). In any case, it's fairly evident that the NuPIC community has a good deal of confidence in the cortical columnar hypothesis being correct. http://brain.oxfordjournals.org/content/125/5/935.full On Mon, Apr 14, 2014 at 12:41 PM, mraptor <[email protected]> wrote: > Hi, > > Can somebody point me to a place where I can find more information > about internal structure of the cortex "minicolumns" and how they > connect with the neighbouring areas ?
