The amplitude of the a-wave of the human electroretinogram was shown to obey the intensitytime relation of the Bunsen-Roscoe Law at very suprathreshold energy levels. This implies that retinal receptor cells are capable of temporal light integration at these energies. Failure to demonstrate a photochemically predicted intensity-time reciprocity failure at very high energy levels may represent insufficient flash stimulus energy. The latency of the b-wave response was shown to be dependent on flash duration at constant energy, increasing as duration increases.
