Dataset refers to the effects of the exposure to different visual feedback conditions on pain perception
 in patients with chronic migraine. It is a 1X4 within-subject study design, in which 38 female chronic migraine patients were exposed to different visual stimuli – positive face, neutral face, negative face, and control (white screen) – during a migraine attack. Visual stimuli were presented 3 times in a randomized order (each condition lasted 40 seconds). Migraine pain ratings and identification
scores were assessed immediately after the observation of each visual condition.
