Network model of the VS tangential cell system, with 10 cells per hemisphere. Each cell is a two compartment model with one compartment for dendrites and one for the axon. The cells are coupled through axonal gap junctions. The code allows to simulate responses of the VS network to a variety of visual stimuli to investigate coding as a function of gap junction strength.

The code is written in Python ( and was tested with
python 2.7. In addition to python, it requires the matplotlib, numpy
and scipy packages (available on the web at,
and Rotation of the images and generation of corresponding
mpeg movies require ffmpeg (
