- •
Blinded assessment of VEPs amplitude decay during 2.5 min examination supported the theory of repeated response decrement deficit in migraineurs.
- •
The repeated response decrement deficit was also observed during visual motion processing in the extrastriatal regions of the visual cortex.
- •
Pattern-reversal VEPs to low contrast stimuli did not show a significant repeated response decrement likely because of their high variability.
