DigiCortex Engine can be used to model some of the emergent phenomena of the developing cortex. In this article we show how spontaneous orientation sensitivity of the primary visual cortex (V1) cells develops in presence of natural video signal and voltage-dependent spike-timing dependent plasticity (vSTDP).

Today, DigiCortex engine has reached version 1.0 after almost two and a half years of development. Version 1.0 brings experimental visualization support for Oculus Rift next-generation virtual reality headset. When running in "Oculus" mode, it is now possible to enter the world of the brain simulation! We will add more and more interesting VR visualization concepts in the near future!

DigiCortex v0.95 brings the early preview of CUDA acceleration. Despite the early stage of the CUDA compute plug-in, simulation performance is more than 7 times faster than optimized multi-threaded CPU code running on a high-end dual 8-core Xeon E5 for large simulations.

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.
