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 ).
