A Study design 1B. Suitcase for mobile EEG equipment for recordings at patient’s home containing: 1) EEG device 2) LED goggles 3) Triggerbox 4) Headcaps in different sizes 5) Power supply. 1C. Unpublished data of migraine patient that underwent our longitudinal study design to assess cortical EEG responses to visual ‘chirp’ stimulation (i.e. short 10-40 Hz pulse train of light flashes), during different phases of the migraine attack. VEP-EEG analyses reveal a visible difference in the harmonic frequency responses between the 1st recording (interictal) and the 4th recording (pre-ictal), after which a migraine attack occured within 24 hours
