  1. MA = migraine with aura, MwoA = migraine without aura. Mean (SD) or numbers
  2. 1Migraineurs with at least one interictal EEG recording
  3. 2Subgroups with both an interictal EEG recording (> 36 h from attack) and a preictal (< 36 h before attack), ictal or postictal (< 36 h after attack) EEG recording
  4. 3Numerical definition: 0 – none, 1 – some, 2 – substantial
  5. The control group consisted of 27 women and 3 men (n = 30) with a mean age of 39.7 (11.5)
