Abstract
The pertinent points of visual neurophysiology and
neuroanatomy are reviewed with particular emphasis on
how retinal light distributions result in perceived
phenomena. The neural modeling techniques used at the
Naval Postgraduate School are discussed. The specific
computer programs used by the author in modeling are
described. These stem from a basic model capable of
calculating the postsynaptic potential and spike
outputs for any sequence of excitatory and inhibitory
inputs. More advanced programs model facilitation,
fatigue, and narrow band motion detection. The most
advanced program models lateral inhibition in an eight
neuron linear array. The lateral inhibition network is
used to show temporal phenomena (null vs. preferred
direction, fast vs. slow speed detection) as well as
spatial phenomena (Mach bands, line sharpening,
disinhibition, spatial frequency response) . Many
suggestions for future modeling work are given.
