From: Altered functional connectivity of the red nucleus and substantia nigra in migraine without aura

Altered effective functional connectivity between the left red nucleus and whole-brain regions in patients with migraine without aura (MwoA) compared with healthy controls (first row). Altered effective functional connectivity between the right red nucleus and whole-brain regions in patients with MwoA compared with healthy controls (second row). Blue signifies decreased functional connectivity, and red denotes increased functional connectivity
