Fig. 2.
Alteration of fractional amplitude of low-frequency fluctuation (fALFF) in the chemotherapy group from pre- (time point 1, TP1) to post-chemotherapy (time point 2, TP2). One cluster (indicated in yellow) in the left precuneus (0, −56, 44) shows a statistically significant decrease in fALFF from TP1 to TP2 (p-corrected < 0.05). The blue crosshair indicates the cluster peak (0, −56, 44) in each plane. The color bar in the right lower panel indicates the scale of the t statistics for the within-group comparison of fALFF between TP1 and TP2.
