The Link Between Place Cells and Grid Cells and Maps in the Brain
32:00 - 38:00 (05:59)
This podcast discusses the theories and evidence supporting the idea that the mechanisms for mapping space in the brain were repackaged and incorporated into the neocortex through the use of similar grid cell and place cell neurons.

The map-building mechanism in the brain, previously known for mapping physical spaces, has been repackaged into a more compact form, and is present in almost every animal for navigation.

The idea of replicating a common element in a more compact and universal version has been proposed as a solution to the replication needed in deep learning networks.

The predictive theory suggests that if grid and place cells are responsible for creating reference frames in the columns of neocortex, then equivalent mechanisms should be present in every column.

Summary
The predictive theory suggests that if grid and place cells are responsible for creating reference frames in the columns of neocortex, then equivalent mechanisms should be present in every column. This hypothesis leads to the search of grid and place cell equivalents in neocortex.
