Be still my beating heart! Super interesting and important. The Mosers show that when rats switch between familiar rooms, each grid module shifts phase independently — and that differential shift across modules drives global remapping in hippocampal place cells.

It has been super fun to work on this, where we learned that:
1) Mouse PFC is needed for model-based override of habits.
2) Separate PFC populations encode a 'policy' and the current 'value'.
3) The policy and value codes alternate theta sweeps towards the goal.
...and much much more!
