DigiCortex 1.0 Released - Visualization with Oculus Rift

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 0.97 - Updated Model of Early Visual System

DigiCortex v0.97 adds further improvements to the model of early vision: thalamic (dLGN) processing. Signal coming from the virtual retina is now passed through a pool of neurons in dorsal Lateral Geniculate Nucleus (dLGN) and projected to primary visual cortex (V1). Cortico-thalamic feedback and inhibition through Reticular Thalamic Nucleus (RTN) is also modeled. Click on the article to read more!

DigiCortex 0.96 - Preview of the Retinal Module

DigiCortex v0.96 brings early support for visual input from the outside world. Input from a web camera or a Sony(R) PS3 Eye Cam can be fed to artificial retina processing stage (using Virtual Retina package from INRIA Neuromathcomp research-team) and then to two arrays of simulated retinal ganglion cells ('ON' and 'OFF' layers). Final destination for the retinal signal is primary visual cortex (V1). Click on the article to read more!

DigiCortex 0.95 - running on CUDA/GPU!

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 v0.94 - Adaptive Exponential Integrate and Fire (AdEx) Neuron Model

SpikeFun v0.94 brings support for Adaptive Exponential Integrate and Fire (AdEx or Brette-Gerstner) neuron model. AdEx neuron model is qualitatively similar to Izhikevich' neuron model, undergoes the same bifurcations and can reproduce various spiking patterns of cortical neurons. However, AdEx model parameters could be directly related to biophysical quantities and its spike initiation is exponential, not quadratic. DigiCortex Engine can simulate neurons with both models in the same simulation. Click on the title to find out more...
