Supplementary Information

This file contains Supplementary Figures 1-12 with Legends, Supplementary Methods, Supplementary Tables 1-3, Supplementary Discussion and Supplementary Notes with additional references. Supplementary Figures 1-3 show representative recording locations in MEC and CA3, examples of global remapping and rate remapping in CA3 (rate maps for the complete cell sample in one animal and for all cells that were active in both environments in all animals), and crosscorrelation matrices for the entire set of grid-cell ensembles. Supplementary Figures 4-12 show additional crosscorrelations for individual cells and cell ensembles, simultaneous recordings from MEC and CA3, experiments addressing contiguity of grid realignment in MEC and global remapping in CA3, analyses of ensemble coactivity and rate distribution across grid vertices, and two models for global remapping in hippocampus during grid realignment in MEC. Supplementary Tables 1-3 show numbers of cells and experiments for individual rats, averaged firing properties of MEC and CA3 cells, and behavioural data.
