The Muller cell of the ver- brate retina provides a splendid example of an accessory cell that exhibits features illustrating every aspect of the complex behavior now associated with glial cells.

The other, published 22 years later, was written by Antoinette Pirie and Ruth van Heyningen ( 1956), whose pioneering achievements in eye biochemistry at the Nuffield Laboratory of Ophthalmology in Oxford, England are known throughout the eye research community and beyond.

Its accessibility, readily identifiable neuronal types, and specialized neuronal connectivity and morphology have made it a model system for researchers interested in the general questions of the genet ic, molecular, and developmental control of cell type and shape.

Based on the proceedings of the 4th International Symposium on Presbyopia, held in Marrakesh, Morocco, June 5-10, 1989

These uncoop erative ganglion cells, which Enroth-Cugell and Robson at first called D (dull) cells, produced transient bursts of impulses every time the distribution of light falling on the receptive field was changed, even if the total light flux was unaltered.
