Our recently awarded ArborIO project has officially made us a partner of the Human Brain Project initiative. The official start of the ArborIO took place Tuesday the 16th of February. The project involves partners in Switzerland (CSCS), Italy (University of Pavia / Trieste), and is concerned with producing a human scale model of the olivocerebellar system. To accomplish that we must push the scientific and computational boundaries of what is possible, to simulate such large scale biophysically plausible neural networks. At the end of the project these models will be available for anyone to run, on HBP’s EBRAINS platform.
