Extended Data Fig. 1: Single unit recordings of shelter-direction and head-direction cells.

(A) Left: Coronal image of post-recording histology showing the track of the neuropixels probe (red). Right: 3D rendering of probe tracks in all chronically implanted mice (B) Example tuning curves for a shelter-direction neuron in the RSP before and after shelter rotation. (C) Tuning curves for non-overlapping subsets of data generated by random sampling. For RSP and SC, the plot on the left is sorted by tuning peak, and the sorting indexes have been used to sort the plot on the right. (D) Summary plot of preferred tuning angle for RSP and SC shelter-direction neurons. (E) Example tuning curves for allocentric head-direction neurons in the SC and RSP. We recorded 2% head-direction cells in the SC, and 6% in the RSP. (F) Summary plot showing the occupancy of the arena during exploratory behaviour in the presence of a second, closed shelter.
