Paper Review: "Grid Cell Firing Fields in a Volumetric Space"

Numenta • Jeff Hawkins and Marcus Lewis

Jeff Hawkins reviews the paper “Grid Cell Firing Fields in A Volumetric Space” by Roddy Grieves, et al.. He first goes through the premise of the paper where the authors recorded grid cells in rats as they go through a 2D arena and 3D maze. The team then explores different ways grid cell modules can encode high dimensional information. Lastly, Marcus discusses a talk by Benjamin Dunn showing simultaneous recordings from over 100 neurons in a grid cell module.
