  • Abstract
  • Look Inside

We developed a new Ganzfeld full-field stimula-tor for ERG, VECP and EOG recordings. Back-ground illumination for light adaptation varied between 0 and 1500 lux. we used strobe flash lightfor stimulating light varying in intensity by 6 steps. Color and neutral density filters were inserted for the stimulating light flash. Stimulus frequency varied between 0.5 and 30 Hz. White flash ERG, scotopic ERG, photopic ERG, oscillatory potentials and flicker ERG could be recorded using this stimu-lator with gratifying results.
