The hippocampus is widely known for spatially-selective responses in individual cells. However, many of its cells do not have easily-interpretable spatial tuning curves or are selective for other task-relevant variables. To better understand the computations played by this structure, it may be necessary to look to population-level features of neural activity and the distributed computations they enable. Here, we focus on two such features: 1) a continuous neural manifold that maps spatial and task structure, 2) spatial representations that “sweep” ahead of the animal as it moves through the en
