The November 2014 GENESIS 2.4 release is the first major revision of the GENESIS 2 neural simulator since the "final" release of GENESIS 2.3 in March 2006. Afterwards, 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. Although GENESIS 2.3 was intended to be the last release of the GENESIS 2 series, it has continued to used and to evolve, with modifications needed to efficiently implement synaptic plasticity in large networks and many contributions from users. This has made it necessary for a new November 2014 GENESIS 2.4 release. This new release is now avalable for download from the GENESIS 2 website http://genesis-sim.org/GENESIS/. If any of you will be attending SfN, you can find out more about it at my poster 99.09 (TT88) on Sat, Nov. 15, 2014, 1:00 PM - 5:00 PM The GENESIS 2.4 release includes: * The 'stdp_rules' object, documentation, and Scripts for implementing spike timing dependent plasticity in networks of hsolved cells * New network connection commands allow distance-dependent connection probabilities and/or weights, or the use of periodic boundary conditions for network connectivity. * The chemesis library for modeling second messengers and calcium dynamics * Various user-contributed bug-fixes, utilities, and improvements. * A new autoconf-based build system, so that a simple "./configure" command will create the appropriate Makefile. This has been tested under recent Linux and Mac OSX versions. The older method is also available for platforms not supported by autoconf. * HTML indexing in the 'genesis' directory and subdirectories, for easy browsing of the GENESIS directory system and documentation. * New tutorial Scripts for chemesis, gpython-tools, purkinje, stdp_rules, VAnet2 Dave Beeman ---------------------------------------------------------------------------- Prof. David Beeman, GENESIS Users Group email: genesis@genesis-sim.org - dbeeman@.colorado.edu GENESIS WWW site: http://www.genesis-sim.org/GENESIS/ ----------------------------------------------------------------------------
