Abstract:

We present a large-scale simulation tool for real-time 3D reconstruction of brain activity in a virtual reality environment. The 3D interactive visualization of the human cortex connectome in virtual reality is achieved by using a gaming engine (Unity 3D). Further, the visualization is bi-directionally interfaced with a real-time neuronal simulator, iqr. As a result, by stimulating populations of neurons with external input currents, we are able to reconstruct neural activity propagating in 3D and in real-time. We explicitly demonstrate causal activity propagation in the parietal lobe, indicative of visuo-motor integration. This is a first step to simulating and mapping large-scale brain activity.
