very important, especially the comparison of vertebrate and invertebrate
transduction mechanisms. The workshop was very successful and the
outcome of the discussions proved it worth the effort. To no small
extent has that success been made possible by Dr. Silke Bernhard who
with a combination of authority and charm together with her extremely
efficient and dedicated staff organized this workshop, providing the
conditions and framework for a scientific debate of outstanding quality
in a friendly and pleasant atmosphere. The great majority of
participants were also very committed to making this workshop
successful. Besides the reports of the four discussion groups, this
publication contains the background papers which were revised by the
authors partly as a result of suggestions of some participants. I hope
this book will give a fair overview of the state of our knowledge of
research in visual transduction. It was a pleasure to edit, especially
because of the friendly and very efficient commitment of K. Geue, J.
Lupp, and A. Eckert and the cooperativeness of most of the contributors.
Particularly I would like to acknowledge gratefully the extensive
efforts and patience of the four rapporteurs, M.L. Applebury, W.H.
Miller, W.G. Owen, and E.N. Pugh, Jr., in compiling, writing, and
revising the group reports. REFERENCES (1) Altman, J. 1985. Sensory
