This example produces a soma trajectory similar to that shown in fig 7a
of Archie, K.A. and Mel, B.W. A model of
intradendritic computation of binocular disparity
Nature Neuroscience 3:54-63, 2000.  Differences are due to synaptic noise.
Successive runs will produce different trajectories in response to randomly
computed synaptic event times.

The out.gif file shows the trajectory first obtained by launching the
mosinit.hoc file.

This example is based on the files from but includes
a sample geom.Rin and
(generated from an optimal response grating)
file to allow autolaunch of the
example via the mosinit.hoc file. The changes to allow autolaunch consist
of moving the mod files from a subdirectory to the top level and a test
in hoc/synapses.hoc to allow automatic loading of the file.

The code which generates synaptic input files (not present in this
example but see the Readme_karchie file for a copy of the instructions
for that package) has been superseded by
the package at
"SNV is a package for generating realistic spike trains in NEURON
simulations. Users create stimulus "movies," use linear-nonlinear cascade
models to generate the response of afferent neurons then map those
responses into synapses in specified locations on a cell."

Please contact with questions about the paper, model
parameters, and usage of the snv system. Contact
for questions about running this example.
