Note from ModelDB administrator: 20170720 This page is a modified copy of the no longer available web site: The page has been updated to provide some of the files from ModelDB (the original web site is no longer working). The model for Olypher and Calabrese 2007 is not currently available through the first link below titled "Matlab code for ...." and we are trying to locate a copy of that file to share (20190906).

Tutorial and model of the leech heartbeat timing network (Release 8/20/99)

This new tutorial includes introductory material, a graphical user interface to the model, and suggested experiments to help the user explore and understand the model.
You'll need three things to run the network leech model: 1) the GENESIS simulation program, 2) the GENESIS script files for the model and tutorial, and 3) an extension to GENESIS that is required by our GENESIS files. Items 2 and 3 are available at this site, and you can GENESIS at Instructions for running the model are contained in item 2.
  1. The GENESIS simulation program
  2. Extensions to GENESIS required by the model of Heart Interneuron Network:
