Title: “Diverse forms of reciprocal antagonistic
interaction in the retina create a dozen different retinal movies, transmitted
in parallel to higher visual centers.”

Abstract:
Reciprocal antagonistic interactions serve as
difference amplifiers that subserve edge enhancement,
directional selectivity, feature abstraction, contrast enhancement and many
other visual functions. These interactions are expressed in a common motif, expressed
in diverse synaptic structures and neural circuits. The final expression of
these interactions leads to a family of a dozen different representations
(retinal movies) of the visual world, each expressed in one of 12 distinct
strata of cell processes within the depth of the retina, and all 12 are read
out in parallel for transmission via the optic nerve to higher visual centers.
