(A) A representative cell which fires similarly in the Centre Goal Box regardless of which route the animal took to get there. The firing rate map for a whole maze session is shown. This is divided into the four possible trajectories but is plotted using one colour axis scaled from 0–20 Hz. Surrounding this, activity in each of the four goal boxes has been enlarged. This pattern of firing suggests that the animal was aware this goal box occupied a single spatial location and was thus one box at the end of two distinct trajectories. (B) Left, the result of Spearman’s correlations comparing the firing of all place cells, from all rats and sessions in each pair of goal boxes, depending on the route taken to get there (i.e. firing in the Left Goal Box at the end of Route 1, the Centre Goal Box when at the end of Route 2, the Centre Goal Box at the end of Route 3 and finally the Right Goal Box at the end of Route 4). Correlations comparing the firing in each box to itself were not calculated and have thus been coloured white. Correlations are generally high, however, correlations comparing firing in the Centre Goal Box when it was accessed using the two different routes are the highest (i.e. Route 2 vs. Route 3 and vice versa), confirming that cells fire similarly in this box regardless of the route taken to get there. This suggests that rats and cells considered the Centre Goal Box to be one coherent spatial location. (B) Right, the results of a shuffling procedure to determine if the correlations are higher than would be expected by chance. Only those correlations between firing in the Centre Goal Box for Routes 2 and 3 are statistically significant (p<0.05). This test confirms that firing in the Centre Goal Box is more similar than would be expected by chance and that this firing is more similar than that between other pairs of goal boxes.
