Photokinetic Analysis of Primate Cone Responses Implies Qualitative Differences from Rod Transduction

Abstract

Diagnosis of functional disorders of the human retina is based on indirect measures of retinal function, such as psychophysical response functions and electroretinography. Interpretation of the data obtained by such measures requires an accurate model of the processes underlying the retinal responses. Recent progress in this regard has been made by Hood and Birch (1993) and others for rod function, but a comprehensive model for the nonlinear behavior of human cone responses has not been attempted.
