Areas across the visual cortex are functionally connected. Certain patterns can induce perceptual illusions/distortions and visual discomfort in most people, headaches in patients with migraine, and seizures in patients with photosensitive epilepsy. This preliminary study investigated visual stimulation effect on human visual cortical functional connectivity (FC). The study found that a 25-min visual stimulation with a stressful pattern significantly enhanced the FC within the visual cortex and altered the FC to V1 in other regions too, with a lasting effect even after the cessation of the stimulation.
