[A] Brain distribution of the two Independent Components IC15 (hot metal scale) and IC24 (azure-blue) identified as significant by independent component (IC) analysis and for which functional connectivity was absent in both migraine with pure visual aura (MA) and migraine with complex neurological aura (MA+) patients scanned between attacks and compared to healthy controls (HC). All images have been co-registered into the space of the MNI template. The numbers below each image refer to the z coordinate in Talairach’s atlas. [B] the bar graph on the right shows the correlation between the 2 ICs in HC, MA, and MA+, p < 0.05 FDR corrected. [C] Time course of spontaneous blood oxygen level dependent (BOLD) activity oscillations during resting state, extracted from the two significant ICs.
