Abstract:   The cortical microcircuit, the network comprising a square millimeter of brain tissue, has been the subject of intense experimental and theoretical research. In parallel simulation has been established as a tool to explore the relation of network structure and dynamics [1].
The explanatory power of such models is limited as half of the incoming contacts (synapses) of each excitatory nerve cell have non-local origins and the brain constitutes a recurrent network of networks.
The talk presents the technology we have developed and implemented in the software NEST to overcome the restriction to local networks by employing supercomputers like K [2].
NEST technology is used in the Human Brain Project (HBP) to explore brain-scale networks at cellular and synaptic resolution.
