WebDec 24, 2024 · Abstract. Photosensitivity is defined as a “photoparoxysmal response” (PPR) to intermittent photic stimulation (IPS) during an electroencephalogram (EEG). The PPR consists of spikes, spike-waves, or intermittent slow waves, ranging from localised occipital spikes (Grade 1) to generalised spike and wave or polyspike and wave complexes (Grade 4). WebIntermittent photic stimulation (IPS) is used as one of the activating methods in electroencephalography (EEG) recordings in the investigation of patients with suspected or known epilepsy.
