In the mid-sixties, John Robson and Christina Enroth-Cugell,
without realizing what they were doing, set off a virtual
revolution in the study of the visual system. They were trying to
apply the methods of linear systems analysis (which were already
being used to describe the optics of the eye and the psychophysical
performance of the human visual system) to the properties of
retinal ganglion cells in the cat. Their idea was to stimulate the
retina with patterns of stripes and to look at the way that the
signals from the center and the antagonistic surround of the
respective field of each ganglion cell (first described by Stephen
Kuffier) interact to generate the cell's responses. Many of the
ganglion cells behaved themselves very nicely and John and
Christina got into the habit (they now say) of calling them I
(interesting) cells. However. to their annoyance, the majority of
neurons they recorded had nasty, nonlinear properties that couldn't
be predicted on the basis of simple summ4tion of light within the
center and the surround. 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."
