Figure 4. mPFC units with anxiety-related firing patterns are over-represented in the population.

Figure 4

(A,B) Cells with positive EPM scores (black circles) have more marked task-related firing than those with negative EPM scores (grey circles), as measured by higher correlations between firing in the two closed (A) and two open (B) arms. Correlation values for grey and black circles are plotted in their respective colors. (C) Distribution of EPM scores for all recorded units with > 100 total spikes. The arrowheads and stars marks the median and mean of the subsamples of units with negative (grey) and positive (black) scores. The distribution differs significantly from that expected by chance (red line). See also Figure S6.
