Intermittent Photic Stimulation

From Wikipedia, the free encyclopedia

In medicine, Intermittent Photic Stimulation, or IPS, 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.

IPS and EEGs are often used to diagnose conditions such as photosensitive epilepsy. The field is relatively new and the details of use of IPS have not been widely standardized. IPS is often used in conjunction with other controllable generators of visual stimuli, such as low-level visual stimulation LLVS.

Photic stimulation may also be used for elicit myoclonus, especially cortical reflex myoclonus when present in photo-sensitive forms.

Also known as Intermittent Photic Stimulation, a treatment system designed to stimulate the visual system for patients with amblyopia. This system uses a low frequency strobed vision stimulus, usually red and at 4Hz, to stimulate the retina to visual cortex neural pathway. The object being to improve the visual acuity of an amblyopic (lazy) eye.
