cqvip:Cognitive processing was investigated interictally in 18 children with migrain e without aura and 18 age matched controls by measuring event related potentia ls (ERPs) and reaction times (RTs) during an acoustic oddball paradigm. Results showed that N100 amplitude evoked by frequent stimuli was significantly smaller in patients compared with controls. Habituation of target P300 amplitude was obs erved in patients but not in controls. Mean RTs were equivalent in the two group s, but migraine children made more errors than controls.
