Habituation of Brain Responses to Sensory Stimuli in Fibromyalgia

The goal of this observational study is to assess event-related potentials and habituation in patients with fibromyalgia. The main research questions are: * Is there a measurable difference in sensory responses between fibromyalgia patients and healthy control? * Could these measures provide evidence supporting claims of hypersensitivity? Participants will: \- receive randomized sensory stimuli (auditory, visual, somatosensory, audiovisual, auditory-somatosensory, visual-somatosensory, and auditory-visual-somatosensory) in blocks of 20 trials.
