  "scope": "Representative connected anatomical model in one millimetre coordinate system. Detailed V3 cellular templates and all supplied anatomical surfaces are retained. Some cortical templates preserve measured human light-microscopy skeletons and radii; noncortical templates are the original procedural V3 models. Template reuse, cell placement, long-range extensions and synaptic assignments are modeled. This is not a full biological cell census, a measured end-to-end human connectome, EM segmentation, or a physiological simulation. Selected conscious sensory and motor routes are represented; other neural networks are outside this model. The cortical display is restricted to the left precentral and postcentral gyri. A separate paired coronal inspection adds six-layer representative samples and actual H01 neurite references; shapes, laminar proportions and new connectivity are modeled.",
