A A heatmap depicts the mean activation of HCPex cortical divisions across seven identified CAPs. Red indicates higher activation, while blue represents lower activation or deactivation. B Surface plots illustrate the spatial distribution of activation (yellow) and deactivation (blue) for each CAP across left (L) and right (R) hemispheres. C A correlation matrix shows the Pearson correlation coefficients between all pairs of CAPs. The color scale ranges from purple (negative correlation) to yellow (positive correlation). Notably, each CAP demonstrated significant anti-correlation with at least one other CAP. CAP-1 showed significant negative correlations with CAP-2 (r = −0.849, puncorr < 0.001, pBH < 0.001) and CAP-4 (r = −0.851, puncorr < 0.001, pBH < 0.001). CAP-2 was found to be strongly anti-correlated with CAP-7 (r = −0.792, puncorr < 0.001, pBH < 0.001). CAP-3 had a significant negative correlation with CAP-5 (r = −0.997, puncorr < 0.001, pBH < 0.001), while CAP-4 was anti-correlated with CAP-6 (r = −0.751, puncorr < 0.001, pBH < 0.001). Additionally, CAP-6 and CAP-7 exhibited a notable anti-correlation with each other (r = −0.786, puncorr < 0.001, pBH < 0.001).
