Figure 2. Identified FC patterns using the proposed feature selection approach.

Figure 2

(A) Heat map depicting patterns of abnormal resting-state (rs) functional connectivity (FC) in patients with migraine without aura (MwoA) relative to healthy controls (HCs). Warm colors represent an increase and cool colors represent a decrease in rsFC in patients with MwoA compared to controls. (B) Consensus map of discriminative rsFCs. The ring shows node weights reflecting the number of occurrences for each region of interest in the consensus map. Red connections indicate significantly higher and blue connections indicate significantly lower rsFC patterns in patients with MwoA compared to HCs. (C) Full view of the most discriminative features formed by the top 100 consensus FCs. The discriminative power of each FC was determined by the average of its absolute classification weights across all iterations of CV. DMN = default mode network.
