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). WebPhotic Stimulation (PS) PS is another standard procedure during routine EEG recording. The procedure is easily carried out with strobe units that flash for 5–10 seconds at frequencies typically between 1 and 35 Hz. PS evokes a rhythmic frequency in the occipital derivations termed photic driving ( Figure 2-9 ).
