SpikeFun v0.91 - Voltage Based STDP

SpikeFun v0.91 is out and brings support for more advanced long-term plasticity - Voltage-based STDP (based on the model of Clopath et. al). Voltage-based STDP is in agreement with more experimental data than conventional STDP models that consider spike timing only.

SpikeFun v0.90 - More Complex Pyramidal Neurons, Demo with 3.52 Billion Synapses and more...

SpikeFun v0.90 is out and brings support for more advanced pyramidal neuron morphologies such as apical tufts and dendritic tree branching. In addition, new milestone has been reached - simulation with 3.52 billion synapses, which is just some 0.5 billion synapses shy of the current built-in simulation limits.

New Milestone - 16.7 Million Neurons, 2.1 Billion Synapses

SpikeFun and its DigiCortex engine have been scaled to accommodate simulation of 16.7 million multi-compartment neurons with 2.1 billion synapses. To my best knowledge, this is the largest-scale simulation of cortical neurons on a home PC. Click on the title to find out more!

Happy First Birthday, SpikeFun

SpikeFun is now 1 years old! This article goes through the progress of the DigiCortex library and SpikeFun demo simulator in the last year and also describes some of the ideas that will be implemented in the future. 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!
