Supplementary Figure 2. Examples of the three patterns of firing rate changes between intended destinations yielding a statistically significant effect. The most prevalent pattern was a high firing rate on journeys to one goal box, and low rates for journeys to the remaining three goal boxes. The example shown in the left is cell 1 from Supplementary Table 1. For 25 of the 32 significant cells (cells 1-25 in the Supplementary Table 1), the firing rate on the highest rate journey (1st) was more than twice the next highest (the 2nd) rate. 6 of the 32 cells (cells 26-31 in the table) showed less than 2-fold differences in firing rates between the highest firing rate journey and the next highest rate journey, and cell 31 (middle plot) is perhaps the best example of a cell with relatively high firing rates on two journeys. However, even for these cells, there was a decrease in firing rates (29% on average) between the highest rate and next highest rate journey. Only 1 of the 32 significant cells appeared to have a high firing rate on 3 journeys relative and a lower rate on the remaining journey (cell 32; right plot).
