Values represent the same analysis outcome as in Table 1, apart from the binarization thresholds that were increased with a factor of 2 and 3. 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).
