The Aperture Problem / Head Direction Cells - July 29, 2020
Channel: Numenta
Date: 30/07/2020

This research meeting contains a couple short topics presented by Subutai Ahmad and Jeff Hawkins.  But first, the research team tries something new. After the previous meeting, there were a few comments and questions posted, and the team decided to address them live, for the first 18 minutes. 

Then, Subutai discusses the aperture problem and discusses a paper, "Contribution of feedforward, lateral and feedback connections to the classical receptive field center and extra-classical receptive field surround of primate V1 neurons." (http://europepmc.org/article/med/17010705) 

Next, Jeff briefly discusses a recent paper that supports the notion that head direction cells are a type of path integration, "Constant Sub-second Cycling between Representations of Possible Futures in the Hippocampus" by Kay et. al, Cell, May 2020.
