Comparisons among nociceptive heat activation map, S2 rs-network, and pIns rs-network. (A) Spatial correlation coefficients between S2-based intrinsic map and pIns-based intrinsic map (rS2|rpin), S2-based intrinsic map and activation map (rS2|activ), pIns-based intrinsic map and activation map (rpin|activ), and combined intrinsic map and activity map (comb|activ). (B) Overlap percentages of rS2|rpin, rS2|activ, rpin|activ, and comb|activ. Number of S2 seeds = 10, number of pIns seeds = 12; Unpaired t-test, *p < 0.05, Error bars indicate standard error.
