Cognitive Computing researchers at IBM are developing a new generation of “neuro-synaptic” computer chips inspired by the organization and function of the brain. For guidance into how to connect many such chips in a large brain-like network, they turn to a “wiring diagram” of the monkey brain as represented by the CoCoMac database. In a simulation designed to test techniques for constructing such networks, a model was created comprising 4173 neuro-synaptic “cores” representing the 77 largest regions in the macaque brain. The 320749 connections between the regions were assigned based on the CoCoMac wiring diagram. This visualization is of the resulting core-to-core connectivity graph. Each core is represented as an individual point along the ring; their arrangement into local clusters reflects their assignment to the 77 regions. Arcs are drawn from a source core to a destination core with an edge color defined by the color assigned to the source core.
