Fig. 2From: 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 P3 component in migraine patients and healthy controls, respectively. P3 is elicited by different stimuli. a Standard stimuli at 425–435 ms; b target stimuli (P3b) at 430–440 ms; c novel stimuli (P3a) at 400–410 ms. Red denotes a positive and blue a negative potentialBack to article page
