The displacement cell is a great idea mentioned. but I am curious how it is actually learned in human? Specifically, for a specific displacement cell, how it can learn to associate to only the grid cell pairs that have t… --- ## [Grid and Place Cells in the Neocortex.

During some recent podcasts, Jeff Hawkins has said a few times that there is now evidence that Grid and Place cells exist in the neocortex. Yet I can’t find any published references to this. Can someone please point me t… --- ## [Locations in the Neocortex: A Theory of Sensorimotor Object Recognition Using Cortical Grid Cells](https://discourse.numenta.org/t/locations-in-the-neocortex-a-theory-of-sensorimotor-object-recognition-using-cortical-grid-cells/4679)

I’m sure this will be a little controversial, but I’m not at all convinced that all cortical columns are actually generating motor commands. Jeff has yet to convince me on that. In motor regions perhaps, but not in all c… --- ## [Should grid cell or displacement cell modules include minicolumns?](https://discourse.numenta.org/t/should-grid-cell-or-displacement-cell-modules-include-minicolumns/4747)

Current implementations of the “location layer” work as a collection of grid cell modules where one or more bumps of activity are essentially “pushed around” as the location being represented changes.
