The Kinetics of Early Intermediate Processes in the Photolysis of Visual Pigments

  • Edwin W. Abrahamson
Conference paper


The sensory process of vision is unique in that the molecules actually receiving the sensory stimulus have characteristic visible absorption spectra. This property not only permits their ready identification but also affords a very sensitive means of monitoring molecular events that follow light absorption. As these spectral changes can be measured precisely on a time scale of the order of milliseconds and less, concomitant with early electrophysiological events, the possibility of relating the two becomes iminent.
