Connectivity maps at different levels of organization. a Diagram of region-to-region flow of visual information. b Cell type connectivity map illustrates which neuronal types and subtypes innervate which. c Intraclass connectome illustrates the patterns of synaptic connections generated by the relative connectivity of individual neurons (colors) of the same type. For example, the green and orange cell constantly innervate the same targets. d Network diagram in which the synaptic connections of multiple populations and subpopulations of neurons can be organized according to their synaptic connectivity. e Tissue digitization. An attempt to capture all anatomical connectivity data within a single dataset. Digitization includes ultrastructural description of synapses and relative distribution of synapses across arbors of target neurons
