The figure shows the complete set of active CA3 cells in the experiments in Figure 1a-c (all from rat 11278). Each row shows one cell (t, tetrode; c, cell). Each pair of columns shows the trajectory of the rat (black) with spike locations (red) to the left and the colour-coded rate maps to the right (blue, 0 Hz; red, maximum rate). Peak rates are indicated to the right. a, global remapping between different boxes in a fixed location; b, global remapping between identical boxes in two different rooms; c, rate remapping after reversal of the colours of the box walls at a fixed location. All cells in each panel are from the same recording.
