Fig. 4From: The impact of attack frequency and duration on neurocognitive processing in migraine sufferers: evidence from event-related potentials using a modified oddball paradigmTopographical voltage distributions of difference P3 components in migraine patients and healthy controls, respectively. a P3dT at 420–430 ms; b P3dN at 380–395 ms. P3dT and P3dN represent the P3 target and novel effects (target minus standard and novel minus standard), respectively. Red color denotes a positive and blue color a negative potentialBack to article page
