(A) Identified publications sorted by brain region with further subdivision of neocortical areas. (B) Breakdown of reports of digital reconstructions by neuron types in the two most popular and two other representative brain regions. (C) Temporal trend of the ratio of interneurons to pyramidal cells reconstructed in the hippocampus and neocortex, highlighting the surge of interest in interneurons in the late 1990s (arrow); (D) Chronological analysis of identified publications by brain region and cell type demonstrating selected upward and downward shifts.
