In particular, cortical visual evoked potentials (VEPs) are used to infer the mass activity of visual cortical neurons. Most, though not all [12], VEP, recordings have shown that the brain of migraineurs with and without aura is characterized by an interictal deficit of habituation during stimulus repetition, and by its ictal normalization [13–16]."}
