Marcus Lewis Reviews “The Tolman-Eichenbaum Machine” Paper - February 15, 2021

Marcus Lewis reviews the paper “The Tolman-Eichenbaum Machine” by James Whittington, et al.. He first connects and compares the paper to the grid cell module in Numenta’s “Locations in the Neocortex” paper. Marcus then gives a high-level summary of the paper and highlights two aspects - how grid cells and place cells interact, and how place cells can represent novel sensory-location pairs. The team then discusses the multiple grid cell modules and mechanisms presented in the paper. “The Tolman-Eichenbaum Machine: Unifying Space and Relational Memory through Generalization in the Hippocampal Formation” by James Whittington, et al.: Papers mentioned: “Locations in the Neocortex: A Theory of Sensory Recognition Using Cortical Grid Cells” by Jeff Hawkins, et al.:
