SpikeFun 0.65 - NUMA Optimizations

SpikeFun v0.65 contains extensive optimizations for NUMA architectures (such as Intel(R) Xeon(TM) E5-2600) with multiple CPU sockets and memory divided per CPU groups. Speed up of over 25% is measured on our reference system. Click on the title to find out more!

SpikeFun 0.63 - Configurable Neurons, GPU Shaders, Variable Cortical Thickness, More AVX....

SpikeFun v0.63 brings support for user-configurable neuron parameters, variable cortical thickness, optimized OpenGL rendering using GPU shaders as well as more hand-optimizations for CPUs supporting Advanced Vector Extensions (AVX) instruction set and much more!

SpikeFun 0.57 - DSI Axon Guidance, Multi-Site EEG, Experiments...

SpikeFun v0.57 has just been released and it is loaded with new features ranging from the new network generation algorithm all the way down to the new command line interface... click on the title to find out what's new!

White Matter Axonal Guidance with SpikeFun v0.54

SpikeFun v0.54 has just been released and it adds the ability to follow anatomical data related to axonal pathways (connectomes). During the simulation build-up, SpikeFun will use connectivity matrices to route parts of axons belonging to pyramidal and thalamic relay neurons. This feature is in a very early stage, so expect lots of improvements and better precision in the future.

SpikeFun 0.5 - Sleepy vs. (Really) Awake Brain...

As described in the previous post, SpikeFun v0.5 is using 3D brain model for neural network build-up (if desired). With quite a big jump in complexity of the neural network, there are some very interesting emerging phenomena that could be observed if the network is fairly large.

SpikeFun 0.5 - Let's get... brainy :-)

SpikeFun v0.5 has just been released and it contains some quite big improvements. How about real 3D model of the brain? If you are interested - click on the title to read more!

Sneak Preview of Things to Come...

While working (very hard :-) on SpikeFun 0.5, I decided to share a small screen capture of the future SpikeFun... Click here, or on the title to see it...

Thalamocortical loops, multi-compartment neurons and more...

New SpikeFun versions comes with multi-compartmental neuron models, thalamocortical system simulations including cortex (6-layers) and thalamus modeling, simulation of fMRI BOLD (Blood-Oxygen-Level-Dependence) and several other cool features!

Yes... now we can do spherical neural topologies!

New SpikeFun update (v0.40) adds initial support for the spherical neural network topology (in a very early and buggy form - i.e. neuron picking is totally flawed!). Spherical topology is very useful, as it easily allows simulating of the "reentry" effect, which is also observed in the vertebrate central nervous system (so-called "thalamocortical loops"). Original idea for spherical topology for simulating reentry effects came from the Izhikevich et. al..

Neural Network View à la "Blue Brain"

I've extended SpikeFun v0.36 to support rendering of the entire neural network, including synapses, in the similar style to "Blue Brain Project" visualizations. Read more...
