*Paper proposes new way to understand how the neocortex works
by Numenta*
Scientists at Numenta propose a major new theory about how the human brain works. While neuroscientists have amassed an enormous amount of detailed factual knowledge about the brain, there remains no unifying theory as to what intelligence is and how the brain produces it. In their paper, "A Framework for Intelligence and Cortical Function Based on Grid Cells in the Neocortex," Numenta researchers describe a broad framework for understanding what the neocortex does and how it works. The paper appears in the journal Frontiers in Neural Circuits. The key insight described in the paper relates to a type of neuron called grid cells. Grid cells exist in an older part of the brain that learns maps of environments. As you move, grid cells keep track of the location of your body relative to these maps. Numenta researchers deduced that grid cells also must exist throughout the neocortex. These "cortical grid cells" track the locations of your sensors as they move relative to the objects in the world. The authors propose that cortical grid cells allow the neocortex to learn models of objects similar to how the older part of the brain learns maps of environments. The paper proposes how we learn the structure and behavior of objects based on locations and location spaces defined by cortical grid cells.
