IC, connectivity index; A-Pmax, maximum anterior-posterior termination zone. Numbers in Macaque and Human columns represent medians with interquartile ranges in parentheses. U indicates the Mann-Whitney U-test statistic, and P gives the P value. Tail indicates whether a left-tailed (l), right-tailed (r), or two-tailed (b) test was used (see hypotheses). This analysis was done with streamline binarization thresholds 7 (macacques) and 0.5 (humans).
