Electroretinographic Evaluation of the Bunseen-Roscoe Law for the Human Eye at High Energy Levels.
Abstract
The amplitude of the a-wave of the human electroretinogram is shown to obey the intensity-time 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 the photochemically predicted intensity-time reciprocity failure may represent insufficient flash stimulus energy. The latency of the b-wave response is shown to be dependent on flash duration at constant energy, increasing as duration increases. (Author)
