Figure 4.

Path-selective cells. A, Example of a cell that showed path specificity for a single path (EN). Left shows mean firing rate on each path. The asterisk (*) indicates significantly greater firing rate in the EN path (Bonferroni-corrected t test, p < 0.05 between all groups). Right shows a heat plot of mean firing rates in 5 × 5 cm grid units. The black lines depict approximate location of the maze. The internal figure shows the mean firing rate across all trials, and the four external plots show mean firing rates on specific paths. The color bar shows firing rate in hertz. B, Example of a cell with path specificity for two paths (WN and EN). The asterisk (*) indicates that WN and EN paths had greater firing rates than other two paths (comparison by Student's t test, p < 0.05, between two groups).
