aData indicate the number of neurons exhibiting selectivity to the five aspects of behavioral factors −99 to 100 ms (A) and 101 to 300 ms (B) relative to the choice-cue onset; A and B correspond to the bins indicated in Figure 8. The values in parentheses indicate the percentage of neurons of the total (n = 1002 in the GP, n = 773 in the PMd, n = 358 in the vlPFC, n = 791 in the dlPFC).
*p < 0.05,
**p < 0.01 between the GP and each of PMd, vlPFC, and dlPFC (Fisher's exact test).
