Figure 4.

Multiphasic neurons mean firing rate (bin = 50 ms, no overlap, z-scored) of all animals in each of the four recorded cortical areas. Red (black) lines depict the activity when reward was at the left (right) hand side. Time t = 0 s marks the moment rats reach the NP. Shaded regions relate to the standard error of the mean (calculated across the total number of recorded cells, described in Table 2). Curves are smoothed with a 10-point moving average filter. Dashed blue (red) vertical lines indicate the approximate beginning of trials (reward) time.
