Space is a sensory-motor sequence in the hippocampus

Recently we published a paper in Science Advances titled Space is a latent sequence: A theory of the hippocampus. I believe this paper offers a view of the hippocampus that is drastically different from the space-centric view. This blog is a companion to the paper, and includes some visualizations and animations that make the ideas easier to digest. I believe anyone who’s interested in the hippocampus will benefit from reading this. Starter code: A Google colab Jupyter notebook is available with starter code. You can run it from the browser without installing anything, and it takes less than 5 minutes to train a basic model and see how it works. Click here for the Jupyter notebook. Place cells — neurons that respond to locations — is a robust phenomenon that is a striking property of the hippocampus, and the currently dominant paradigm of hippocampus is of representing space in Euclidean terms. Hippocampus neuron activations are often visualized as place fields. However, anomalies to t
