Abstract

The first two major groups of papers deal with morphology and function, respectively. The papers in the morphology section follow in a logical sequence the same sequence that occurs in the transduction of light to optic nerve activity in the retina. The first paper in the section is that by Moyer on development, structure, and function of pigmented epithelium. In it he presents some speculative and highly provocative ideas such as a role for the epithelium in active transport of Clions; control of visual sensitivity and acuity by photomechanical response of melanin granules; and direct electrical stimulation of iris muscles through tight junctions. Cohen, in the second paper, deals with receptor morphology and its relation to visual excitation. Among other topics he discusses receptors as waveguides, localization of visual pigment within receptor structures, and descriptions of receptor terminals and their contacts with second-order neurons. The outer plexiform layer is treated
