For those unfamiliar with place cells like I am here’s a very interesting video about their activations:

It’s neat to see place cells in action for an acoustic experiment(2nd half of the video) rather than a traditional maze. I agree with his speculative conclusion that the hippocampus produces a manifold where behaviors are like time-trajectories of place cell activations. Sounds exactly like a sequence of feature-locations in HTM sensory-motor inference and the Taaken’s Theorum predictive manifolds from Ogma’s Feynman Machine paper.
