Topic: intra-area communication

The communication of spike events constitutes a major bottleneck in simulations of brain-scale networks with realistic connectivity, as for example, the multi-area model of macaque visual cortex (Schmidt, 2018). The model consists of 32 cortical microcircuits, each representing a downscaled area of the visual cortex at the resolution of single neurons and synapses with many connections both within and between areas. While synaptic transmission delays between areas are in the range of milliseconds, they can be as short as 0.1 ms within areas. This requires frequent spike communication between c
