Thank you for the quick reply. I'm in Los Angeles, so I hope someone does record your presentation at NASA.
A similar question arose when I read "Thinking, predicting, and doing are all part of the same unfolding of sequences moving down the cortical hierarchy." (On Intelligence, p. 158.) I'm sure this is a FAQ, but do you have some writings or presentations about how a CLA would receive feedback signals coming down the hierarchy?

Jeff, I wrote this presentation a couple years ago for a workshop on sensory motor integration. That workshop was held at the Santa Fe institute and I don’t believe it was recorded. The genesis of the workshop was a paper written by Murray Sherman and Raymond Guillery where they point out that every region of the neocortex (as far as they have looked) has cells in layer 5 that have a motor function. The big idea is that every region of neocortex does sensory inference and generates behavior. There are no pure “sensory” regions and no pure “motor” regions. It is one of those beautiful results that make you slap your head and say “of course!” I have always envisioned the CLA as modeling a section layer 3 in a region of the neocortex. Layer 3 is the primary input layer and is therefore doing inference on the input to that cortical region. Layer 5 is driven by layer 3 and has the cells that innervate muscles, or more often project to some sub-cortical area that generates behavior. I see how two CLAs, one for layer 3 and the other for layer 5 can work together to learn a sensory motor model of the world where today’s CLA is purely sensory. There is a lot I don’t understand but there is enough that I think we can make progress. I gave this presentation again earlier this year at Numenta. It wasn’t recorded. It looks like I might give it again this fall at NASA Ames here in Silicon Valley as there are a few roboticists there interested in it. I don’t mind recording it if someone could take care of the logistics.

Subject: [nupic-dev] Mentioned presentation on action with CLA? Hello. In the introduction for the NuPIC Hackathon Kickoff, Jeff Hawkins talks briefly about the need for CLA integration with action. In response to a question, he says "We haven't done experiments with motor interaction. I have a presentation, I think about it." Is the presentation about motor interaction with CLA available? http://www.youtube.com/watch?feature=player_detailpage&v=yShNQvJEP6A&t=2188 Thank you, - Jeff Thompson
