In medicine,<unk> , or<unk> , is a form of visual stimulation used in conjunction with electroencephalography to investigate anomalous brain activity triggered by specific visual stimuli, such as flashing lights or patterns.<unk>  and EEGs are often used to diagnose conditions such as photosensitive epilepsy. The field is relatively new and the details of use of<unk>  have not been widely standardized.<unk>  is often used in conjunction with other controllable generators of visual stimuli, such as low-level visual stimulation LLVS.<unk>  stimulation may also be used to elicit myoclonus, especially cortical reflex myoclonus when present in photo-sensitive forms.<unk>  may be used to stimulate the visual system for patients with amblyopia. This system uses a visual stimulus that is usually red in color with a frequency of about 4 Hz to stimulate the neural pathway between the retina and the visual cortex. The objective is to improve the visual acuity of an amblyopic (lazy) eye.
