The GENESIS 2 simulator home page

http://genesis-sim.org/GENESIS is the home page
for the stable, "classic" GENESIS 2 simulator.

After the "final" release of of GENESIS 2.3 in March 2006, development efforts shifted towards GENESIS 3 (G-3), a 21st century neural simulator without the limitations of GENESIS 2 and other simulators that were developed in the late 1980's and 90's. At this point, G-3 is still in the development stage.

G-3 is based upon the Neurospaces project. Development releases and documentation are available at the Neurospaces Home Page (http://neurospaces.sourceforge.net). They will also soon be available through links on the main page for the GENESIS simulator at http://genesis-sim.org.

The Sourceforge genesis-sim-users mailing list is the best means of obtaining individualized help with GENESIS 2 or 3. You may subscribe at https://lists.sourceforge.net/lists/listinfo/genesis-sim-users.

Recent GENESIS 2 developments

Although GENESIS 2 is user-suported, rather than being being actively developed, users continue to contribute new libraries, documentation, and simulation scripts. Questions posted to the genesis-sim-users mailing list usually receive a prompt response. GENESIS 2.3 continued to be widely used used for large network models consisting of multicompartmental neurons, and for projects in modeling courses, such as the recent Latin American School on Computational Neuroscience. Although it was intended to be a final release of the GENESIS 2 series, it has continued to evolve, with modifications needed to efficiently implement synaptic plasticity in large networks and many contributions from users. This made it necessary for a new November 2014 GENESIS 2.4 release.

This new release is now avalable for download at
http://genesis-sim.org/GENESIS/genesis-ftp/genesis-2.4-src.tar.gz.

Further updates to GENESIS 2.4 continue to be made and can be found at the Repository for the continued development of the GENESIS 2.4 neural simulator at https://github.com/genesis-sim/genesis-2.4

The latest updates to the GENESIS 2.4 release include:

The GENESIS 2.4 release includes:

Initial release of PGENESIS (parallel GENESIS) version 2.4

Some recently added GENESIS 2 tutorials and simulations

Ultimate GENESIS Tutorial Distribution

This is a complete self-paced GENESIS modeling course, combined with GENESIS binary and source distributions and installation instructions. It provides an easy way to get everything by downloading a single package. The latest version may be browsed from this link.

This latest version was used as course materials for the tutorial Constructing biologically realistic neuron and network models with GENESIS at CNS 2014 presented by Hugo Cornelis.

You can download it as:

UGTD2-CNS.tar.gz or UGTD2-CNS.zip

VAnet2 - An efficient hsolved GENESIS version of the Vogels and Abbott (2005) model that was used in the Brette et al. (2007) review of network simulators. It serves as a tutorial on the use of hsolve with network models in order to achieve speedups by a factor of 10 to 20. The 'VAnet2-batch.g' script is intended to be extended for testing GENESIS spike timing dependent plasticity (STDP) implementations with hsolve. This script would be a good starting point for models that use more realistic cells and connections.

ACnet2 - An auditory cortex model that also serves as a tutorial and template for creating neocortical network models.

fMRInet Is a variation of the ACnet2 model that illusrates how to provide unusual stimuli, such as the effects of the electromagnetic fields that are produced during an fMRI experiment. This is done by using a 'script_out' object to provide the stimulus at clocked intervals.
