Note: Data is presented as mean (standard deviation). Mean and max t-scores were extracted from active voxels that overlapped for the BOLD data (E2, MEC, and MECDN) and PW data (PW_ss,none, PWDN_ss,art, PWDN_ss,art+BOLD, PW_hd,none, PWDN_hd,art, and PWDN_hd,art+BOLD) separately. Individual statistical maps were thresholded at an uncorrected p<0.01. Abbreviations: tSNR = temporal signal to noise ratio; E2 = single echo (second echo, TE = 25ms); MEC = multi-echo combined; MECDN = multi-echo combined and denoised; PW = perfusion-weighted; PWDN = perfusion-weighted denoised; SS = surround subtracted; HD = high-pass filtered, demodulated.

*** = p<0.001,

** = p<0.01,

* = p<0.05, Bonferroni-corrected.
